- Printing questionsHello!
I'm trying to develop an application to print PDF files, using JPedal.
Two questions:
1) I'd like users can specify printing properties, like size,
margins... following an example on JPedal site I tryed:
// new attribute set
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
// dialog
printJob.printDialog(aset);
// read dialog properties
PageRanges r = (PageRanges)aset.get(PageRanges.class);
PageFormat pf = (PageFormat)aset.get(PageFormat.class);
but it doesn't work... :(
Is there a way to set those parameters via code? I need to set margins
to 0,0,0,0...
2) I'd like to improve the quality of printed docs... I think it uses
a very low quality to render my PDF (like 72dpi or so), is there a way
to increase dpi? In a PDFProducer for TFax I was able to do that
passing a bigger BufferedImage to Jpedal, is there a way to do the
same thing here (without redifining the print() method)?
Thanks!

- need Java book for a C# / C C++ proficient programmer?hi,
I've never cared for Java before but now i feel like learning it. I'm
an MCP and a pretty experienced programmer. Also, i plan to take the
SCJP and maybe the SCMAD exams.
Is there a java book out that is for a programmer?? I already have a
copy of Hebert S. java reference, that would be my last option. Also,
i would want the books to somewhat cover the exams I plan to do.
Thanks so much

//add name in string p so that
//p = "my name is joe"
}

- CachedRowSet and double column typesHi, there,
I have a CachedRowSet obtained from Sun's CachedRowSetImpl and I'm
trying to use it with a MySql database. I have a table test that has
the basic column types. If I use a plain double column type and I have
to update a row with the double field having the fraction part
something like 1/3 (i.e. 0.3333....), then the acceptChanges fails with
the error
javax.sql.rowset.spi.SyncProviderException: 1 conflicts while
synchronizing
If I have a double(12,2) column type or the like (i.e. I limit the
precision) or if I have a fixed fraction part (something like 0.5,
let's say), then acceptChanges works fine.
I havent logged the sqls generated by the acceptChanges of the
CachedRowSetImpl, but I remember encountering something similar on some
different software components and what was happening in that case (and
I suppose it's happen in this case too) is that the sqls generated were
trying to find the original row using all the fields in the row and not
only the primary key, as it should be the case, i.e. there was
something like :
update test set f1=x1, f2=x2, f3=x3 where f1=y1 and f2=y2 and f3=y3
Now, since there's that "unlimited" number of digits after the decimal
point, it wouldnt have found the original record (maybe because there
was a different number of digits used to represent the same number on
the MySql server and on the MySql client).
My question - is there a way to tell CachedRowSet how the row
identification should be done (to say what goes into the "where"
clause)? Eventually is there a smarter, free implementation of
CachedRowSet ?
Thanks, Don
PS. See used code and table data bellow.

- JAXB & Excel 2003I downloaded Microsoft Office 2003 Reference Schemas from:
http://www.microsoft.com/downloads/details.aspx?familyid=fe118952-3547-420a-a412-00a2662442d9&displaylang=en
Then I tried to use JAXB on them, specifically excel.xsd and
excelss.xsd. The first one passes OK, but doesn't contain Worksheet
element, which is the root element for Excel 2003 documents saved as
XML. The other schema, excelss.xsd, contains the definition of this
element, but doesn't pass through JAXB. The output of:
xjc -p generated excelss.xsd
is:

- Newbie Question: Eclipse RCP - three questionsHi all,
I'm trying to develop Eclipse RCP database based application and I've faced
following problems.
First :
I don't know where can I create and dispose the ImageRegistry ?
Class WorkbenchAdvisor doesn't seem to be right place to do this, I couldn't
find the method
like initializeImageRegistry.
Second:
Where should I keep for example the database connections or references to
the beans
shared among different parts of the application especially further plugins ?
Third:
Is there any example of the real database driven RCP application with source
code available
or at least an article describing this topic ?
Thank's in advance

- reading \n from a fileI am reading from a file and storing in String.
I need to separate a word so that part of it goes to next line
abc\nxyd
I am moving this text to button.setText() and this should
appear on the button as
abc
xyz
for that I am putting newline escape there.
it is not working. I have tried putting unicode string in
place of \n that also is not working.
how to do it?

- Java Window/GUI HelpOk im trying to create a program in java right now and my knowledge of
it has proved somewhat .... limited.....
Info:
Im making a program using javaspaces to simulate an auction over the
network.
Requirements:
1) user can add a lot to the auction
2) browse current lots on sale
3) users can withdraw their item from sale.
OK now this has to be done as a GUI which is what is hindering me.
The only type of GUI work i have done have been fairly static.
Just a plain window with a few buttons and such which might bring up a
picture or change some text in a text box or something.
But what im having trouble with now is the whole GUI design and how to
go about it.
Say i had 3 butons in my window |Add| |Browse| |withdraw|.
Clicking any of these should change the whole structure of the window
and i dont know how to do this..
Itd be a case of clearing half of the window off and redrawing over
the top of it.
Unless i went the route of having an extremely simple window with 3
buttons, clicking each would open up a new window with the desired
options...
What would be the best way to go about it? and how would i go about
implementing it? just a few tips are needed :)
Im really not a windows fan... a console app would take an hour or so.
This is gonna keep me going for aaaaaages :$
I hope im making sense and not babbing too much - 36 hours without
sleep and a huge abundance of caffeine is warping my mind o.O

- Ant : how can I use properties to store nested elementHi all,
I have a build script which uses <fileset> nested in <path> to store
the classpath and then this <path> is used in javac. e.g.
<path id="MY_CLASSPATH">
<fileset dir="${build.dir.lib}" includes="**/*.*"/>
<fileset file="${global.lib.j2ee}"/>
</path>
<javac
srcdir = "${project.compile.src}"
destdir = "${project.compile.dest}">
<classpath>
<path refid="MY_CLASSPATH"/>
</classpath>
</javac>
I just wondering is it possible to store the fileset in the properties
file so that I can reference it in other place? I want to do a fileset
instead of writing all the jar file names explicitly.
e.g.
In the properties file:
project.compile.classpath=dir:${build.dir.lib}:file:${global.lib.j2ee}
(or something like that....)
then in my build.xml:
<javac
srcdir = "${project.compile.src}"
destdir = "${project.compile.dest}">
classpath = "${project.compile.classpath}">
</javac>

- HTTPConnection - verbose error messagesI have a java application that polls an asp page for the purpose of
inserting to a data base. I am interested in seeing verbose (ie
unfriendly HTTP error messages) when there is an internal server error
(code 500). Below is the code snippet that makes the application's web
connection and captures the response messages.
String user = "";
//String user = "Someone";
try{//create url object
urlWithQueryString =
"http://www.someaddress.com/lpt/lpt_login.asp?User=" + user +
"&FName=Alonzo&LName=Garbonzo&timeStamp=20060110_1106";
System.err.println("urlWithQueryString ln 35: " +
urlWithQueryString);
url = new URL(urlWithQueryString);
}catch(MalformedURLException mURLE){
System.err.println( "MalformedURLException thrown in WriteToWebDB: ln
41 " + mURLE.getMessage() );
System.err.println("");
return NetworkStatus.NETWORK_CONNECTION_PROBLEM;
}
try{//open connection. Write data succeeds or fails here
connection = (HttpURLConnection)url.openConnection();
inputStream = connection.getInputStream();
connection.setInstanceFollowRedirects(true);
}catch(IOException iOE1){
try{
System.err.println( "IOException caught in WriteToWebDB: ln 52");
System.err.println("Connection response code ln 53: " +
connection.getResponseCode());
System.err.println("Connection message ln 54: " +
connection.getResponseMessage());
System.err.println("Exception message ln 55: " + iOE1.getMessage());
}catch(IOException iOE){System.err.println("IOException caught ln 56"
+ iOE.getMessage());}

********************************************
Below are three examples of server output - the first two have
defective connection strings to force server error and one is a good
connection string that inserts to the data base. Note that defective
string passed from the application returns an error message without
much information while the defective string passed from a browser
returns a verbose and detailed error message. Can anyone help in
discovering a way to recover verbose detailed error messages in the
java application? Any help is greatly appreciated.

- negative dns caching problem *resolved* (was Re: JDK 1.5.0 patchsetAfter months of fighting with this, today I stumbled upon the answer. It
was a java command line test case that led me to it.
>From the command line, FreeBSD's JDK does -exactly- what it is supposed to
with negative caching. My test case involved restarting BIND, adding a
firewall rule for a host's name servers, having Java try to resolve the
name (and of course fail), having Java wait while removing the firewall
rule and having Java try again to resolve the name. All the while I was
watching network traffic with tcpdump.
Exactly as it is supposed to, the JDK tried again and succeeded after I
removed the firewall rule.
So this meant that it had to be something to do with Tomcat or
commons-daemon/jsvc.
On a whim, I removed the entry for Tomcat's native libraries, and it
started to work correctly.
Then I did an ldd against libtcnative, and found that I had compiled it
with gcc 4.2.1. Knowing that there are problems with gcc 4.2, I
recompiled with gcc 3.4.6. It continues to work correctly.
So this turned out to be a multi-pronged problem. Earlier I was building
a version of the JDK that somehow never read java.security, and that
required wiping out the work directory entirely and bootstrapping off the
Diablo JDK. Then, something about compiling the Tomcat native libraries
with gcc 4.2.1 was apparently creating this bad behaviour situation.
So if you're using Tomcat, and you want to use the Tomcat native
libraries, do not compile them with gcc 4.2. In fact, you probably will
want to make sure you compile them with the same major.minor version of
gcc you used to compile libapr just to be safe. The Tomcat native library
IS capable of screwing your DNS resolution.

I can not get JAVA to run in IE7 Beta. Actually, it didn't run under IE6
either. I've exhausted my limited knowledge already. Any advice? Links?

maybe try mozilla, firefox, opera or whatever else.
why use obsolete and / or beta navigators ?
Good luck

I would appreciate any insight available.

- Question about Master and Working Memory from Chapter 17 of the Java Language SpecificationOk the following is from Chapter 17 of the Java Language
Specification.
"A variable is any location within a program that may be stored into.
This includes not only class variables and instance variables but also
components of arrays. Variables are kept in a main memory that is
shared by all threads. Because it is impossible for one thread to
access parameters or local variables of another thread, it doesn't
matter whether parameters and local variables are thought of as
residing in the shared main memory or in the working memory of the
thread that owns them.
Every thread has a working memory in which it keeps its own working
copy of variables that it must use or assign. As the thread executes a
program, it operates on these working copies. The main memory contains
the master copy of every variable. There are rules about when a thread
is permitted or required to transfer the contents of its working copy
of a variable into the master copy or vice versa."
Does this mean that, say, in the following code, there are two working
copies of the integer variable X (one belonging to aThread and one
belonging to bThread) and one master copy?
public class TestThread {
public static void main(String[] args) {
aClass a = new aClass();
Thread aThread = new Thread( a );
Thread bThread = new Thread( a );
aThread.start();
bThread.start();
}
}
class aClass implements Runnable{
int X;
public void run( ) {
while (true) {update();}
}
synchronized void update(){
X++;
}
}

- Variable scope access questionHi,
I am not sure my question is valid or not. It is the following:
public class MyClass {
public void doA() {
int num = 10;
doB();
//Now, num value has been changed
}
public void doB() {
//I need to access and change the value num inside doA. But I don't
know how to do it.
}
}
Is this possible? Thank you for your help.

- Known problem with JComboBox?Hi,
just wondering if this is a known problem:
I have to set JComboBox.setLightWeightPopupEnabled(false) due to the
constellation of my framework.
Now the scrollbar of the combo won't be updated as long as the box is
entirely displayed within my JFrame. As soon as part of it is out of the
window the scrollbar will work.
What's that all about? Is there a "semi lightweight mode" or something like
that?
Thanks.

- Error handling java GUILet's say that I'm reading the inputs from a TextField widget:
JTextField jt = new JTextField(20);
String text = jt.getText();
if ( !text.equals("OK") )
{
// print some error message to the user
}
If the input is bad, I want to print some error message to the user but
at the same time I don't want to exit my GUI. How do I do that? Should
I be using exceptions? Can someone point me to some sample codes
somewhere on how error handling is performed in JAVA?
Thanks

- Why Java's math expression (power) is so inconvenient and error prone?Hi,
My program need a lot of calculation of power. In many programming
languages,
2**3 = 8; //or
2^3 = 8;
The syntax is clean and easy. But in Java,
Math.pow(2, 3) = 8; //It is so long, and complicated and error prone
Again, in many languages,
EXP(1) = 2.7 //e value
But in Java,
Math.pow(Math.E, 1) = 2.7 //You see, so complicated
Normally, in one calculation, 2**3 or EXP(3.5) is only part of
expression, like "a + b**3 + EXP(-a)". In Java, it will be very long and
error prone!

- Questions about porting a Java applicationHi all,
I have a Java application that I want to port and I have read the better
part of [1]. The application that I want to port unfortunately has a
specific structure that does NOT make it possible to adhere to the
practices. What is the general thing to do in such a case?
As far as I can tell from the Win32 starter script for the application it
insists on an application
directory with the following structure
INSTALL-DIR
|
+---- bin
|
+---- doc
|
+---- lib
Any advice about this?
Kind regards,

- dragging a transparent JFrameI'm able to get a transparent JFrame using java 1.4+ on Mac OS X. I
simply set the JFrame's background to a transparent color. However,
with a transparent color (any alpha component less than 255), when I
drag within the JFrame (not the titlebar), it drags the entire JFrame
with it. This makes for unexpected results when dragging an object
within the JFrame that also drags the entire JFrame.
Any ideas?

- JDK + SDKHi,
why i need JDK and JRE together. I don't understand it:
1. I can install JDK + JRE in a packet on my maschine. So i have two Folders
JDK1.5.0_06 and JRE1.5.0_06
2. only JDK
3. only JRE
If i install JDK so there is a folder in it with JDK1.5.0_06/jre/ there the
JRE ist include.
So why i must install jre separately? I want to that my browser must be use
this included jre in jdk !!!
There is the diffrent between?
thx a lot
