- Hibernate - one-to-many problem/questionsHi all,
DB: MySQL
Hibernate 2.0.1
I have a very simple (one-to-many) relationship between two tables
QUESTIONS ANSWERS
------------------ ----------------------
id: long id: long
text: string qid: long
text: string
qid is foreign key.
In my Question.hbm.xml I have the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD
2.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="my.Question" table="questions">
<id column="id" name="id" type="long">
<generator class="identity"/>
</id>
<property column="text" length="200" name="text" not-null="true"
type="string"/>
<set name="answers" table="answers" lazy="false">
<key column="qid"/>
<one-to-many class="my.Answer" />
</set>
</class>
</hibernate-mapping>
There is more than one answer for a question always.
What happens is when I load a question with answers I only get one answer
back, though
in the hibernate trace I see the result set returned more answers and
objects were initialized.
What is wrong?
I tried to use list instead of set with id as index column, but result was
N+1 entry. Additional entry was null.
I still don't understand what should I use as an index column in this case.
Please help.
thanks in advance,
Igor

- Capturing web camera video streamHello gurus,
Does java have a standard support of web cameras? I'm interested in
capturing the video stream coming from my webcam using J2SE if this is
possible.
Thanks gurus.

- session attribute copied to new sessionI want to use session attributes to save info on a user who wants to
navigate my site. When the user logs in I use:
HttpSession sess = request.getSession(true);
sess.setAttribute("customer", customer);
where customer is an object I have instantiated earlier. This works
fine and I can view values from this object using the following code
in index.jsp:
CustomerBOImpl cust = null;
if(session.getAttribute("customer") != null){
cust = (CustomerBOImpl)session.getAttribute("customer");}
out.println(cust.getFname());%> <%out.println(cust.getLname());
This prints out the first name and last name just fine. The problem
comes when someone else tries to access the same index.jsp. It opens
up the page, gives them a separate session ID, but this different
session contains the same customer object of the last person who
logged in.
My question is: What is the proper manner to set session attributes
and then retrieve them in a JSP servlet?

- Problems installing Cocoon 2.1.5.1 on BEA Weblogic 8.1sp2Hi,
I have built a cocoon.war file, and deployed it on my BEA Weblogic 8.1
Sp2 (Windows 2000) installation. The deployment works without
exceptions, but when I try to access cocoon through
http://localhost:80/cocoon I get the following error message (stack
trace):

I have added xercesImpl-2.6.2.jar and xml-apis.jar to the weblogic
server CLASSPATH. I have also checked the cocoon.war file to see if
the loggerkit-1.2.2.jar is included - it is!
Is there anybody with an idea about how to fix this ?

In the button_ActionListener you use yourJTextField.getText() to retrieve

- Problem with loading an image to a PanelSalutations everybody. I want to load an image into a panel. I have
sub-classed the JPanel class in order to be able to override the pain
method, like this :
public class ImageCanvas
extends JPanel {
Image image;
public ImageCanvas() {
super();
this.setBackground(Color.white);
}
public void paint(Graphics g) {
if (image!=null)
{
g.drawImage(image, 0, 0, this);
}
}
public void SetImage(Image img)
{
image = img;
int iW = Math.min(image.getWidth(this),this.getWidth());
int iH = Math.min(image.getHeight(this), this.getHeight());
this.setSize(iW>>1,iH>>1);
//this.setSize(image.getWidth(this)>>1,image.getHeight(this)>>1);
setVisible(true);
this.repaint();
}
Now I use this code in order to load my image into a normal jPanel :
(this is the snippet of code that executes loading the image :
//Display images
Image img =
Toolkit.getDefaultToolkit().createImage(strFilePath);//strFilePath of
course contains the path where the "image.png" is located
MediaTracker tracker = new MediaTracker(this);
tracker.addImage(img, 0);
try
{
tracker.waitForAll();
}
catch (InterruptedException exI)
{
System.out.println("Error while waiting tracker"+
exI.getMessage());
}
jCanvas.setMaximumSize(jPanelImg.getSize());
jCanvas.SetImage(img);
jPanelImg.revalidate(); //jPanelImg (type = JPanel) contains
jCanvas which is of type //ImageCanvas
jPanelImg.repaint();
However, when I use this program it loads the image all right but the
background is full of trash. Also if I try to load multiple images
then they all get jumbled together...
How can I clean this up ?
Thanx alot !

- PluginI have installed Java plugin J2RE 1.4.2 downloading it with IE 6.
(and it is in a folder under this path IE/Java/J2RE1.4.2 ).
Netscape uses this path automatically or have I to download another plugin ?

- Calling java from the command-line: 40 timesMy company has an ETL that runs 40 'threads', and does logic similiar
to a Java object I have created. I am trying to convince them to call
my code instead (from the 40 threads) so we only maintain one code
base (a BIG issue).
My concern? Sinc eit is a command line program, not a service, each
'call' will start in it's own JVM - correct? so this machine will
have 40 JVM's running at the same time? Do I need to be concerned?
What issues am I not considering? The machine is a Solaris box with
96G of memory and 28 processors. How much overhead does a sinlge JVM
need?

- what's wrong with this thread?Why is it when i create and add a new thread to a vector, the vector,
instead of adding a new thread, replaces all the old threads with the
a new one.
I know it's hard to understand, just run the code below, you'll see
what i mean.
////////////////////////////////////////////////
import java.util.*;
class ThreadTest
{
static Vector vec = new Vector();
public static void main(String[] args)
{
for (int x=0; x!=10; x++)
{
vec.add(x, new TestTrd(""+x));
((TestTrd)vec.get(x)).start();
System.out.println("------------------------------------");
}
}
}
// the thread
class TestTrd extends Thread
{
static String clientName= null;
public TestTrd(String name)
{
System.out.println("Original value: "+clientName+" <-- should
be null");
clientName = name;
System.out.println(" New Value: "+clientName);
}
public void run()
{
}
}
/////////////////////////////////////////////////////
OUTPUT:

- Getting access to printDialog attributesI need to print 8 html files. These files are loaded into JEditPanes
which are then passed to a PrinterJob object. It would be nice to query
the user with the print Dialog ( printDialog() ) at the beginning of the
print sequence but not for each successive file. It appears that the
printDialog() sets a series of attributes in the PrinterJob object. My
code, on n+1 documents, sets some attributes, but clearly, not all of
what the printDialog() method sets. And, I have no way of knowing if the
user changes something (such as page orientation, number of copies,etc).
Is there a way to get the full PrintRequestAttributeSet out of the
PrinterJob object so that it can be set for the next print()? I can send
the code if needed, thanks - Lou

- Can't Call Methods in Class Created W/ ReflectionI am testing a class that I'll need later. I need to be able to load one of
a number of classes that all implement a particular interface, then call 3
methods in them. When I run the test class, I get the same error
(indicated in comments below). I've gone over this several times and
compared it with tutorials online, but I can't find my error (which, the
way my brain works, means it's probably something simple and obvious and
I'm just to caught in it to see what's wrong).
The code for the calling class and the called class are below.
Thank you for any help!

- javax.net.ssl.SSLException: untrusted server cert chain with FireFoxFor an in-house project, I have a web server (Apache) with a
self-signed certificate. I can access everything via https: just fine.
The reason for wanting https is to add security to the .htaccess
passwords. This all works just fine.
FWIW, I'm using FireFox, and simply added the self-signed certificate.
However, no Java applets will load. I get the following when trying
to load InHouseApp (one of the applets):
load: class InHouseApp not found.
java.lang.ClassNotFoundException: javax.net.ssl.SSLException:
untrusted server cert chain
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a([DashoPro-V1.2-120198])
[rest deleted]
I have complete access to the various client machines (both desktops
on the lan, and laptops that will be out in the wild). What do I need
to add to prevent this exception? Also, as certificates aren't my
strong suit, are there any step-by-step detail instructions on what to
do?
TIA

- IllegalAccessError with axis and wsseHello,
Complete java newbie here. I am trying to set up a client for the web
service described at:
https://thefinder.tax.ohio.gov/StreamlineSalesTaxWeb/WebService/About.aspx
I am using JDK 1.4.2 on AIX 5.3. I downloaded the axis 1.4 and axis-
wsse 1.0 packages,
and all included jar files are in the CLASSPATH.
Right now I am just trying to get the sample "TestClient.java" program
provided on the above web page to work. So far, everything seems to
compile ok. However, trying to run the TestClient program produces
the error:
Exception in thread "main" java.lang.IllegalAccessError:

just trying to set up a client for a remote web service.
Thanks.

java-programmer, JavaMail send mail without using default port 25
Hi,
I must send email to a server that listen in port 2025,
how I can do it using JavaMail??
Thank to all.
Nicola Trevisan
PS: I insert my code so you can tell me where to place new code.....I hope
props = System.getProperties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "127.0.0.1");
session = Session.getDefaultInstance(props);
in = new FileInputStream(file);
msg = new MimeMessage(session, in);
msg.setFrom(new InternetAddress("email***@***.com"));
msg.setRecipient(Message.RecipientType.TO, new
InternetAddress("email***@***.com"));
transport = session.getTransport();
transport.send(msg);

If you want to send email to a server that listens on a non standard
port you are out of luck. You can specify which port to connect to
for your *local* smtp relay (per the other replies), but if it is the
remote server that listens on a non-standard port it cannot be done
with Javamail.

That does not sound like a very likely host. Do you have a mailserver
running locally?
About the only other trick is this.
Properties props = System.getProperties();
if ( CustConfig.needPasswordToSend )
{
props.setProperty ( "mail.smtp.auth", "true" );
}
// Get a Session object
session = Session.getDefaultInstance( props, null );
I do have complete working example, but the source is not free.
See http://mindprod.com/products.html#BULK
See http://mindprod.com/jgloss/javamail.html
and follow the link to the tutorial. The docs are impossible, but the
tutorial is fairly easy to follow.

Why would it ignore your port specification?

It shouldn't, but with port 25 increasingly blocked by ISPs it is
conceivable that a server would listen on a non-standard port and
some 3rd party perform a redirect-type enhanced DNS service, for
example. I would add that my followup was only based on the poster
writing, "I must send email to a server that listen in port 2025" and
does not mention anything about their own relay. I just assumed
they're testing something out especially as the 127.0.0.1 address in
the exception is a dead giveaway they are not setting a local smtp
server. I think they they Javamail sends directly.
I would add to the original poster a potential hack: that they could
do an MX lookup on the domain they are sending do, enter that as
their mail host property, set the port property to 2025 and that
*should* work. Because it is inbound mail to that server the SMTP
transaction would be the same as your own relay sending it on.

However, you are now doing the work of the mailserver. If it is down,
you are supposed to try later. You are supposed to be able to send all
your mail to one server and have it distribute it.
Perhaps the practical way out is to have a local mailserver, or a
local proxy mailserver such as the one that comes with Zaep.

java-programmer >> JavaMail send mail without using default port 25
THANK TO ALL!!
I must describe you what I must to do. (and sorry for my english)
I must test some anti-spam product for my thesis.
Now I work in local and I have a Local MailServer and a program that is an
anti-spam SMTP.
I write a program like an "smtp stress", but I send a database of e-mail.
I must test what e-mail are view as spam and what as legal e-mail.
I take advantage from the situation to ask you if you know some anti-spam
program, to test it.
They must be anti-spam that work in SMTP so not for the home user.
I tell you thank again!!
Bye

I try what tell me Yu SONG and it work!
Thank you Yu SONG, thank you very much.
I can't try to send the mail to another server....because I have only my PC.
Have a nice day!!!

Exactly, there is nothing fake about hard coded if statements, unless
you want to call everything that is manmade fake.
The problem with hard coded if statements as an implementation of
intelligence isn't fakeness, it is quality. Unless there are a huge
number of if statements, you're going to notice pretty quick that this
intelligence isn't thinking very deeply on a Turing test. It is
practically impossible to make a good intelligence that way. You would
probably need billions or trillions of 'if's to make something like a
human. At the very least you would need to use a computer to write that
program for you, which is totally violating the spirit of hard coded if
statements.

- Ideas, Making a graphical grid look like ISO viewHi, hope my question is not too abstract.
I'm drawing a square grid and I have mouse events that return
coordinates of that grid. Now I'd like to make that grid look like an
iso view. Illusion of 3D, seen from an oblique angle, as is typical in
conquest and exploration games.
Affine transform shear takes me close, but I think it's not going to get
me all the way. I think the problem is, I don't really want the
vertical lines to stay parallel, because that makes it look like the
"far end" is fatter, instead of converging to some vanishing point (The
squares in the grid should end up being trapezoidal, I think).
So two problems, 1., how to draw my grid in rectangular coords but have
it look like an iso view, and 2., how to translate the Point from the
mouse event, into the coordinates of my grid.
If Affine transform is still the way to go, I can keep studying it.
Right now I'm thinking I may actually need to work out the geometry of
the iso view, draw it explicitly, and then find the mouse coordinates by
iterating through the boundaries of my graph. This is nasty, since
AffineTransforms would make it so easy.
Maybe there's a better way I'm not thinking of, such as, instead of
bounding my grid by "lines", construct it from "shapes", and then I
could add a listener to each shape, or something like that. That sounds
treacherous too.

- Looping over arrays.Isn't it a waste of resources to loop over arrays this way:
for (i = 0; i < myArray.length; i ++) {
// do something
}
... as opposed to create a variable to hold the value of
myArray.length first, like so:
int len = myArray.length;
for (i = 0; i < len; i ++) {
// do something
}
This way the length of the array doesn't have to be recalculated on
every iteration? Or am I completely wrong?
TIA,
AJ

- reason for sporadic long full GC pause times?!?....Hello folks,
in our java business application our customer realize sporadic very
long pauses caused by full gc's.
Normaly the app runs smoothly with acceptable gc- and
full-gc-pausetimes. (gc=0.0xx sec / fullgc <=2 sec)
But sometimes during 8 hour work the occurs full gc's with 90-150
seconds (!)
which our customer complains about - of course.
In the first step I thought that our JVM-settings were wrong:
-Xms450m -Xmx450m -XX:NewSize=32m -XX:MaxNewSize=32m
-XX:SurvivorRatio=8 -classpath....
--> long full gc pauses occured sporadicaly.
I thought that the Newsize is too small -> wich implies the too big
tenured space -> which could be the reason for too longs full gc's. I
decided to use -NewRatio=4 Parameter.
And I also lowered the max. Heap size to Xmx350m, because the gcviewer
told me that the memory usage was only about 290 MB.
With the new settings
-Xms350m -Xmx350m -XX:NewRatio=4 -XX:SurvivorRatio=8 -classpath....
our customer had the same experience that sometimes the full gc's
pausetime took more than 100 sec's.
Additionally we/they relaized that the full gc freed not enough memory
so that the full gc frequency raised up to a point where no minor gc
were done - only full gc's !
Due to that I raised Xms and Xmx
-Xms512m -Xmx512m -XX:NewRatio=4 -XX:SurvivorRatio=8 -classpath....
which enables the JVM to free more memory at full gc (already tested),
but I fear this will not help to solve the sporadic problem with the
long full gc pause times at customer side.
Does anybody have an idea what could be the reason for the
extraordinary long full gc pause times?
Info btw:
customer PC's all have 1 GB RAM and the throughput of the application
was in any case >= 99,8% !
The problem with the long full gc pause times was never reproduced in
our lab / dev.-deptmnt.
Thanks in advance

- Integrating servlet container into my stand alone AppHello Everyone,
I had this idea for an application I would like to write. I want
to write it as a java application, but be able to output
program-generated .html into an Internet Explorer window. Sending the
generated html to the IE window is easy... just using the Runtime
class. But I want the Internet Explorer window to be able to make http
calls back to my application for form submissions. I didn't want to
have to force my users to install Tomcat just so the internet explorer
could pass back information to the servlet in my .Jar file.
How hard is it to add a servlet container and respond to http post's
from the localhost internet explorer window? This is all from my .jar
file and not from a web application running under tomcat remember. The
only http requests coming into my application will be from that one
internet explorer window... so its really acting like a
single-user-local-machine Tomcat server. But I dont want the burden of
forcing Tomcat on people.
I suppose you'll say pick a standard application or a jsp/servlet
solution, but not both.... but I think there is a lot of flexability
to this method, being able to generate GUI screens on the fly in the
IE window is really exciting.
Thanks,
Greg

- JInternalFrame/JDesktopPane questionHello,
Is it possible to add a JDesktopPane to components other than
top-level components (RootPaneContainer interface implementors like
JFrame, JDialog, etc.)? I'd like to contain a set of JInternalFrames
within one side of a JSplitPane. I don't see a way to do it.
The functionality I'm looking for is a way to create a set of
components that can be dragged around within one side of a JSplitPane.
If there is another way to do that outside of JInternalFrames, I'd be
happy to hear about that as well.
Thanks,

- servlet calling servlet stopped by securityI have two servlets in the same tomcat webapp (A and B) both normally
accessed from the web. Sometimes A needs to access B and I use http to
do that. Actually 'B' is about a dozen other servlets, still all in
the same webapp.
This works just fine until I turn on security constraints. When I do
that and request A the login form works as normal and invokes A
correctly. But when A needs to invoke B I get another logon form
instead of B. This would be okay, I can hack through that, but I only
know the user name, not the password for A's session.
Is there a simpler way to have one servlet in the same webapp invoke
another without having to go through security? I cannot just do java
to java, there are too many entry points (ie cases of 'B') They are
all volatile and need to be exposed to the web.
Thanks for your help

- question about keeping the GUI and logic separateHello,
I have a question about keeping logic/processing code off of the GUI.
In a couple of other languages I'm familiar with, there is usually a
method called FindComponent which will iterate through a form and get
the component matching the name in the argument.
For example, in VS.NET lets say I have a grid (table) on a form, the
form represents one class. I then put the code for getting and
processing data in another class. After any processing occurs (and
the results are placed in a dataset), I need to bind the dataset to
the grid. But the grid doesn't have knowledge of where the dataset
came from... so how does the data get shoveled in there?
In the data processing class, there's a local variable of grid type
and it's gets bound to the grid in the form, like so (sorry about the
VB):
Class SomeClass
Sub doSomething(ByVal c As Component)
Dim localGridView as GridView
Dim localDataSet as DataSet
' MyGrid lives on Form1
localGridView = c.FindComponent("MyGrid")
localGridView.DataSource = localDataSet
' So even though the GUI hasn't a clue as to what is going on, the
current data is now displayed to the user.
localGridView.DataBind()
End Sub
End Class
Does Java have an equivalent of FindComponent, or a something similar
to the code snip above?
I'm using Java 6 here. I did try looking at c.getComponent() but
there's only one valid index... 0 and it represents the
javax.swing.JRootPane. Anything after 0 throws an index out of bounds
error. There are 3 JButtons and 1 JList on the panel. I want to add
some strings to the JList...
public class MyGUI() extends JFrame
{
GUIUtils u = new GUIUtils();
public MyGUI()
{
//
// snip
//
myButton.addActionListener (new ActionListener()
{
public void actionPerformed (ActionEvent e)
{
try
{
u.doSomething(MyGUI.this);
}
catch (IOException ioe)
{
ioe.printStackTrace();
}
}
});
}
and...
public class GUIUtils
{
public void doSometing(Container c) throws IOException
{
listModel = new DefaultListModel();
listModel.addElement(value);
// I want to put the listmodel in the JList now but how do I get
this code to know about the JList in MyGUI?
}
}
Suggestions are greatly appreciated.
Thanks!

- Making hand Hand Held Devices Easier to UseMy partner comes to me every once in a while utterly flummoxed by some
hand held device for example a cell phone, a wall phone, a stereo, an
alarm clock (no kidding -- this beast is quite an intimidating device
it has over 20 buttons), and lately a digital tape recorder.
The problem is these devices have ten thousand features. All she
wanted to do was place a cell phone call or record a telephone
interview. The other features just got in the way.
There are two problems:
1. The other features distract from the basics. There are two many
buttons and too many menu items.
2. The devices have modal traps. Even if you know how to do the
simple operations, it is easy to hit the wrong button, get off in the
weeds and not know how to navigate the device back to a familiar
state.
Imagine a cellphone I could hand to my 4 year old grandson and say
"hit 7 to call me, hit 8 to call your mother, hit the red button for
an emergency" Nothing else the child could do would hurt or confuse
the phone.
Imagine I cellphone I could give to my mother. I say "When you want
to call make a call, hit the call button, use the up down arrows to
select a person from your friends list. If you get to the bottom and
it still not there, choose new person, and they will automatically be
added to the end of your list, but will drop off automatically
eventually if you don't call them.
Imagine a digital tape recorder I could give to a child. I restrict it
so that there are only buttons, record, play, fast forward, rewind.
you can't overwrite anything recorded. There is no erase button.
Imagine a PDA that starts allowing only the simplest functions.
Everything else is hidden. Once you have used and apparently mastered
those functions it offers to teach you yet another function. You can
decline or ask to lean something else. It never reveals too much of
its functionality at a time. It remembers the learning state of
several users.
A few other ideas for hand helds:
1. AC power outlets should have a DC jack built into the wall plate
using some new style plug that delivers a variety of voltages. The
tips of the prongs would receive 12, the base 1.5 with perhaps bands
for 9, 6, 3 in between. The plug on the device would normally only
tap just one voltage, but it would be free to tap all 5. There would
be no matching problem. One plug fits all. It would relieve the
clutter of ac adapters in the typical home office.
2. could it be possible to have a universal charging stand so that you
can wall mount it and put any device in it for a recharging by
induction. Another feature of the charging stand is it would also
tell and device in it the latest accurate atomic time. You could then
create a "wand" you recharge with the correct time then wave at the
microwave or any other non-portable device to update its clock.
3. Could every product be given a UPC number or equivalent so that you
can find an online manual for any device without fuss. Software too
should get such numbers so you can automatically track the latest
version, the replacement or the author. Software then could keep
track of your possessions (software and otherwise) and periodically
poll for a recall message, an important update etc.

- a unusual codesthe codes:
-------------------
Object[] stuff = new Object[5];
stuff[0] = "eggs";
stuff[1] = new StringBuffer( "flour" );
stuff[2] = 3.56;
stuff[3] = 'c';
stuff[4] = 123;
stuff[0]="33";
for( int i=0; i<stuff.length; i++ ) {
System.out.println( stuff[i] );
}
------------------
It seems odd.....
followings is what I guest. please tell me whether it's correct, thank
you very much
1:
what I think is because that the Object Class is any class's
superClass, so it can point to any type (right?), but in these codes it
only have Object Class's interface, not the interface which it point
to.
is it right?
2:
stuff[0]="eggs"
in this sentence,the JVM create a String object(right?), although it's
a String object and of course it has all the String object's
interface, but what the reference(stuff[0]) can access is only the
Object Class's interface.not the String interfaces(just like
concat(),charAt()....)
is it right?
3:
stuff[0]="eggs"
System.out.println( stuff[0] );
and when print it,the print function call stuff[0]'s toString()
function,and this toString() is the String object's , not the Object
Class's
is it right?
thank you very much

There is. You start from scratch with a JComponent and implement
