- I am having trouble with OJB and locking when adding things that have cascading relationshipsHi all, I am using OJB and I can't seem to add a record to the
database if that object contains another object that is a) mapped in
the mapping and b) not already in the mapping. The error I get is:
OJB works reliably in all the other test suits:
-- adding any object and not imposing any connections, ie, they have
no elements that need to cascade
-- retreiving results (either with a criteria or alll records)
I dont know whats going on and would appreciate som ehelp - thanks in
advance

There was 1 error:

public void testAddProjectWithNewEmployer()
throws Exception {
// the pk for the Employer class is id and I didnt

addEmployer is basically just a more specific method that in turn
calls:

- Problem with Session Beans stateHi, I'm currently making a session bean, which will eventually act as
a Shopping Basket.
I have implemented the bean so that it just accepts a string (which
will eventually be an object reference), and the user can add and
remove strings.
Unfortunately, if I access the same bean from another machine and
create an instance of the session bean, they are shown the same
contents as from the other machine.
The session bean type is set to stateful (and I have tried stateless).
Can anyone point me in the direction of the problem please?
Cheers,

- tomcat/applet question...this is really weird, in tomcat/webapps/<appName>I have a jsp AND an
applet.. I'm using a package called smack for writing jabber clients
(http://www.jivesoftware.org/smack/), so:
in jsp:
<%@ page import="org.jivesoftware.smack.*"%>
no problems...
in applet:
import org.jivesoftware.smack.*;
when try to compile get told this package doesn't exist...
package is where all packages are supposed to be in Tomcat
(C:\tomcat\common\lib) and, again, the jsp has no problems with it, but
the applet, which is in exact same location as jsp, for some reason
can't find it..
(in applet am even getting en error (identifier expected) on
system.out.println()... don't know what to make of this..
this is line: System.out.println("test");...)
weird thing is, if I hide System.out.println() line get told package
smack doesn't exist.. if I don't hide System.out.println() line get
ONLY identifier-expected error on System.out.println() line..
would appreciate any help... thank you.. Frances

I agree very much.
BTW, there's another comment from Bracha in the very same paper that's
confusing (me): He says "The Java virtual machine does not directly support
overriding of methods with different return types. This feature is supported
by the compiler.". What does this mean? Does this mean that the different
return types are gone at run time? Here's an example:
static class A {
static A create() { return new A(); }
public A m(A a) { System.out.println("A->A"); return a; }
}
static class B extends A {
static B create() { return new B(); }
public B m(A a) { System.out.println("A->B"); return (B) a; }
public B m(B b) { System.out.println("B->B"); return b; }
}
public void testOverriding() {
A a_a = A.create(); // static type A, dynamic type A
A a_b = B.create(); // static type A, dynamic type B
B b_b = B.create(); // static type B, dynamic type B
A a2 = a_a.m(a_b); // prints: A->A
A a3 = a_a.m(b_b); // prints: A->A
A a5 = a_b.m(a_b); // prints: A->B <== overriding works
A a6 = a_b.m(b_b); // prints: A->B <== overriding works
B b2 = b_b.m(a_b); // prints: A->B
B b3 = b_b.m(b_b); // prints: B->B
}
public void testReflection() {
try {
System.out.println(
B.class.getMethod("m", new Class[] {A.class}).getReturnType()
== B.class
); // prints: true <== reflection works, too
}
catch (Throwable t) {
throw new RuntimeException("Laufzeitfehler", t);
}
}
So there's obviously some runtime support for overriding methods with a
different return type, because in this example both the overriding and the
reflection worked. Then what did Bracha mean?

- Applets and J2SE 5.0 - problems?I set my IE browser (corporate edict to use IE...ugh)
to use the 9/30 FCS release of 5.0
Whenever I visit a page with an applet, the browser
crashes.
Someone at our local user group (www.javasig.com)
mentioned something about version mismatches (???).
Anyone else experience this?
btw, kudos to Calvin Austin (J2SE 5.0 spec lead) and
the rest for a very organized and efficient release.

- JTable and optimal column width.Hi!
I have a JTable which has to columns filled over an 'String[][]'. Is it
possible, to set the cell width to the longest value in an column?
I found a solution with String.lengt() over Google, but this doesn't work
correctly because the value of String.length() doesn't fit exactly. I think
this is because the proportional fonts.
Greetings,

- JCE - load key from stringHi All,
We're trying to use JCE to encrypt some data. The issue is key storage.
We want to store it in some database, so the question is how to
re-create the key for decryption from varchar2 column?
The key in string form looks like this:
cryptix.jce.provider.key.RawSecretKey@3bfce353
This can be stored in the database easily. But how to load this into
KeyStore back?
TIA

- Form doesn't submit onUnload in NetscapeDear Netscape/Javascript/Java gurus,
I am trying to submit a form onUnLoad when the user accidentally
closes the browser before clicking on a link to complete the
transaction.
On IE, this works fine.
But on Netscape or Mozzilla browsers, the form would simply not submit
when
the browser is closed.
here is the code.
<script language="JavaScript">
function CheckWindowClosed() {
document.MyForm.submit();
}
</script>
<body onLoad="FunctionHandler();" onUnload="CheckWindowClosed();">
Kindly let me know if there is any workaround or fix where I can get
this working on Netscape.
Thanks and Regards,
Yash

- XPathAPI(node, xpathStr) & XPathContext.getDTMHandleFromNode(node) slowHello,
I am using xalan 2.7.0: http://xml.apache.org/xalan-j/
As I run XPathAPI.eval(node, xpathStr) over and over again on several
nodes, it gets slower and slower.
This is documented in the XPathAPI documentation, and it suggests to
use the low-level XPath API:
http://xml.apache.org/xalan-j/apidocs/org/apache/xpath/XPathAPI.html
I am now using the low-level XPath API as follows:
XPathContext xpathSupport = new XPathContext();
PrefixResolverDefault prefixResolver = new
PrefixResolverDefault(document);
XPath xpath = new XPath(xpathStr, null, prefixResolver,
XPath.SELECT, null);
and then, for each node:
int ctxtNode = xpathSupport.getDTMHandleFromNode(contextNode);
XObject object = xpath.execute(xpathSupport, node,
prefixResolver);
It gets a bit better, but still, after using over and over again on
several nodes, it gets slower and slower.
I think that the problem is that
XPathContext.getDTMHandleFromNode(child) does not free memory.
Test this simplistic example yourself:
++++++++++++++++++++++++++++++++++++++++++++
import org.w3c.dom.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import org.apache.xpath.*;
import org.apache.xml.utils.*;
public class Test {
public static void main(String[] argv) throws Exception {
int numChilds = 100000+1;
System.out.println("Building a document with " + numChilds + "
childs");
Document doc =
DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
Element root = doc.createElement("root");
doc.appendChild(root);
for (int i = 0; i < numChilds; i ++) {
Element child = doc.createElement("child");
root.appendChild(child);
Element subChild = doc.createElement("sub-child");
child.appendChild(subChild);
Element subSubChild = doc.createElement("sub-sub-child");
subChild.appendChild(subSubChild);
subSubChild.setAttribute("title", "title" + i);
}
XPathContext xpathSupport = new XPathContext();
PrefixResolverDefault prefixResolver = new
PrefixResolverDefault(doc);
XPath titleXpath = new XPath("sub-child/sub-sub-child/@title",
null, prefixResolver, XPath.SELECT, null);
Runtime r = Runtime.getRuntime();
System.out.println("Evaluating XPath for each " + numChilds +
" childs");
NodeList nodeList = root.getChildNodes();
int size = nodeList.getLength();
for (int i = 0; i < size; i++) {
long start = System.currentTimeMillis();
Element child = (Element) nodeList.item(i);
int ctxtNode = xpathSupport.getDTMHandleFromNode(child);
//String title = titleXpath.execute(xpathSupport,
ctxtNode, prefixResolver).toString();
long duration = System.currentTimeMillis() - start;
if (i < 10 || (i % (numChilds/10)) == 0)
System.out.println("child #" + i + "\t took " +
duration + " ms." +
"\tfreeMemory: " + r.freeMemory() +
"\ttotalMemory: "+r.totalMemory());
else if (i == 10)
System.out.println("printing some selected childs only
from now on...");
}
}
}

Here you can see an example of the result:

++++++++++++++++++++++++++++++++++++++++++++
each time I call xpathSupport.getDTMHandleFromNode(child) it does not
free the memory,
and so it gets slower and slower.
How to solve this problem?
Some people has suggested to use the DOM4J package instead of Xalan.
However, we already have quite a lot of software using Xalan and
changing the code would have some cost.
Is it possible to solve this problem without discarding xalan?

- data lost issue using socketsHi,
I have an interesting issue with socket programming.
I would like to send String based information via Sockets.
As it could happen, that a part of the information gets lost on its
way to the client, I would like to send before all such packages the
size of the package as a "short" value (or something equal, but not
string because you can never be sure that your string completely
arrived ).
Does anybody know what is an elegant solution for this problem?
I send the strings using:
PrintWriter out = new PrintWriter(client.getOutputStream(), true);
out.println("test");
Thanks,

Odd. Would you pleaes download the latest appropriate version of
oracle's driver and either run this code in a standalone program
getting your connection directly from the driver, or get the driver
to the front of the -classpath argument in the startWeblogic script,
and then run this code in the server again?
thanks,

java-programmer, problem with xercesImpl.jar
I'm deploying a simple XML parsing servlet using the latest
2.5.0 xerces jars in it's lib directory.
This servlet runs fine on my local machine, but when I deploy it
to the production server, the JRE throws a java.lang.NoSuchMethodError
for the method
method parse(Ljava/io/InputStream;Lorg/xml/sax/helpers/DefaultHandler;)V not found
This method is definitely in the latest xerces jar, so I'm guessing
it's picking up an obsolete jar file somewhere before the current
jar in the classpath.
Unfortunately I have little control over the production server, so
can anyone suggest how I can force xerces to use the actual
latest library?
Thanks,
Sean

java-programmer >> problem with xercesImpl.jar
can you manipulate the CLASSPATH-variable of your production server?
make sure the 2.5-version is in the classpath.

- ServerSocket & multiple clientsNeed help please.
I am trying to write a small client-server application that uses a
ServerSocket that allows connection of two clients via two ports (one on each
port, say 3000 & 4000).
I've tried different techniques, but always get the first client working but
the second client waiting until after the first client has ended (see code
snippet below).
How should I approach this (without the use of threads)?
(I am using the loopback address of "127.0.0.1" as both clients are on the
same PC)
private ServerSocket ss1;
private ServerSocket ss2;
private Socket socket1;
private Socket socket2;
try
{
ss1 = new ServerSocket(3000);
ss2 = new ServerSocket(4000);
}
and then
socket1 = ss1.accept();
socket2 = ss2.accept();

- Sessionhandling with Apache AxisHello Group,
i 've already written a littlr webservice with Apache Axis.
My Service starts a thread to process some data. The Client may
Access the output via different functions.
Everything very fine.
But if i kick the Client and the Session times out after 30
minutes, the thread is still running... and running... and running...
I want to tell the Service to kick the Thread after a timeout,
maybe this should possible via a Session.
How can i find out if a Session is timed out?
Thanks for your help and a happy x-mas (ok ok, some days to early :-) )

- HttpUrlConnection caching ipHello,
I got an ip caching problem when using HttpUrlConnection class.
When using the code :
URL url = new URL("http://a.domain");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
The VM seems to cache the ip address associated with the domain "a.domain".
If the ip associated with this domain change, the VM still connect to the
old ip. The only way to connect to the new ip, is to restart the VM.
I have tried
java.security.Security.setProperty("networkaddress.cache.ttl", "0");
but it does not work with HttpUrlConnection (it works fine with InetAddress
class for instance).
Any idea ?
Thank you,
Christophe

- read gps bluettoth on applet pda - javacommHi all,
I'm a student..
I wrote an applet for PC that reads GPS data from serial port (using
javacomm)....
I would like to have the same applet on my pda, an IPAQ h1940 with bluetooth
gps receiver ....
I'm using javacomm and driver for pda found on www.teilo.net , I followed
the steps of the site, but it doesn't work... :-(
any questions:
- where have I to put javax.comm.properties, CESerial.jar and comm.jar ???
in which directory?
- how can I add the directory containing the javax.comm.properties, and the
paths to both jar files to my classpath? modifying the registry? which key?
(I searched in the registry but I didn't find none of java, path, classpath
etc...)
- if I want to read bluettoth data, I have to read a virtual serial port
(COM8?), right?
thanks all!

- Rollover button problemI'm building a site in Dreamweaver MX where I have a set of rollover
buttons. These buttons go dim when the mouse is over them. When clicked,
another image appears on a different part of the page (I built this using
the Set Nav Bar image function). This all works fine on my Mac, using my
browser safari and Internet Explorer. But on a PC using Internet Explorer
the rollovers dim but when clicked nothing happens. Does anybody know why?
I can paste the code if that helps anybody . I'm not too good at
understanding Java script code so let me know what bits might help
Thanks

- How can I make my applet call another Web page?Hi All,
Would anyone know a way to have an applet call another Web page so
that, after the new page is loaded, if I hit the back button then I go
back to the page where the applet is at?
I don't need to know about button action events or about layout
managers or anything like that, just the URL processing code, or a
good reference.
Thank you,
S.

- java6 does it address default focus on a modal formIts always been near impossible to dynamically set a field with the
default focus when a form (perhaps previously instantiated) is
setVisible - if the form is a modal dialog.
Does anyone know if Java 6 addresses this?

- Packing Resource-Based App Into a .JARI have an application which uses outside data files. That is, it has
lines of code like this:
DataReader.loadFile("data/MyFile.dat");
Right now the app is just a bunch of .class files and I start it on
the command line from the appropriate directory to ensure that the
data files can be found.
But I want to package the app as a .jar (a .jar which includes the
data files) and be able to run the .jar from any directory. That is,
when it's running, java should search for the data files relative to
the .jar root, rather than relative to the root where the process was
started.
How can I do this?
Thanks,

- security-roles: application.xml vs web.xmlHi,
does anybody know how a webmodule behaves when It is assemble in an ear
containing the web module and I include security-roles in both the
application.xml and web.xml? I have been browsing both the j2ee and servlet
specs, but I haven't found any description of mandated behaviour. I have
tested a little with sun one appserver7. This appserver seems to ignore the
security-roles defined in the web.xml. What's more, don't mentioning
security-roles in the application.xml and only use the web.xml for mapping
security-roles breaks the login process.
Does all this mean that security-roles in the web.xml file can only be used
for standalone web applications and not for web modules who are part of an
ear?
Cheers

- Quick help needed. Code runs, but one problem cannot be solvedHey, guys. I designed this code for guessing numbers.
The program should pick a random number between 1 and 10, inclusive
both. Then repeatedly prompt the user to guess the number. On each
guess report to the user that he or she is correct or that the guess is
high or low. Continue accepting guesses until the user guesses
correctly or choose to quit. Count the number of guesses and report
that value when the user guesses correctly. At the end of each game,
prompt to determine whether the user wants to play again. Continue
playing games until the user chooses to stop
Here is the problem, I let the random number print, so I know what
number is it. But when I input that number, instead of showing up
"Congratulations...", it shows up the correct number I entered is too
high. Please let me know what is going on. Thank you
//Code started!
import java.util.Random;
import java.util.Scanner;
public class HighLow
{
//
// Plays the Hi-Lo guessing game with the user
//
public static void main(String[] args)
{
boolean done = false;
boolean playAgain = true;
Random numberGenerator = new Random();
int randomNumber, numberOfGuesses, userNumber;
Scanner scan = new Scanner(System.in);
//
// Constants for messages to the user
//
final String guessMessage = "Enter your guess (-1 to quit): ";
final String tooHigh = "Sorry, the number you entered is higher than
my number.";

number.";

final String playAgainMessage = "Play again?";
while (playAgain) {
//
// Pick a random number
//
randomNumber = numberGenerator.nextInt(10) + 1;

- menu drawn behind canvasHi,
I have a JFrame with a menu bar and inside the the frame a canvas. When I

the menu is always (partly) drawn behind the canvas. How do you set the
