- IDE for Java?I downloaded the Sun product, and find it feature rich but slow. Can someone
recommend a more basic (freeware) IDE which will help a newbie without

few languages, but want to by-pass some of the learning curve for this
project.

- Java Object Persistence (JSP & Java)Hi all.
I'm currently working on a simulation with a web frontend. The
simulation is based on 3 components:
- A Webfrontend
- A persister (which is the object of my quetsio :-)
- A WorkHorse
The Workhorse is doing the actual simulation while the web frontend is
used to interact with the Simulation (queueing and dequeueing new
events to the simulation stack).
Now my question is what the best choice for the persister would be.
I found http://www.prevayler.org/wiki.jsp which looks nice but I don't
know if it's the best choice. Is there a library that transparently
saves and loads whole Object dependencies from an SQL Database, or is
an Object Cloud better?
What is your experience with this/other libraries?

- JTextPane: Workaround for invisible text with hanging indents?Hi all,
I have a hanging indent requirement for paragraph formatting:
<http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/text/StyleConstants.html#FirstLineIndent>
"The amount of space to indent the first line of the paragraph. This value
may be negative to offset in the reverse direction. The type is Float and
specifies the size of the space in points."
A search of Sun's bug database for [set]FirstLineIndent indicates that Sun
has fixed a number of bugs related to rendering negative first line
indents. Does the code I've written below demonstrate another rendering
bug? I'm typing invisible text on multiple platforms with the latest
stable JDK and Mustang beta:
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;
public class InvisibleText extends JFrame {
public InvisibleText() {
JTextPane tp=new JTextPane();
SimpleAttributeSet attrs=new SimpleAttributeSet();
StyleConstants.setFirstLineIndent(attrs, -150.0f);
StyleConstants.setLeftIndent(attrs, 150.0f);
tp.setParagraphAttributes(attrs, true);
JScrollPane sp=new JScrollPane(tp);
sp.setPreferredSize(new Dimension(300, 200));
getContentPane().add(sp);
}
public static void main(String[] args) {
InvisibleText frame=new InvisibleText();
frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
While typing text finally appears at the left indent position of
subsequent lines.
Assuming my code correctly invokes this API, can anyone come up with a
workaround to make the text appear while it is typed?
Many thanks,
Adam

- Linux/X-Windows unable to set focus on a modal form (Consulting $ anyone)It appears whenever a modal window is opened on Linux X-Windows the
focus is stolen from the window and you CANNOT use the keyboard or any
peice of code to return focus to the form - let alone set the focus in
the textbox.
This is not just for my modal forms but for something as fundamental
as JOptionPane or simple code like this:
JFileChooser chooser = new JFileChooser();
if (chooser.showOpenDialog(parentComponent) ==
JFileChooser.APPROVE_OPTION) {
}
From trolling through posts I can see no answers which is really sad
for Linux good for Microsoft I guess. How can we deploy on Linux if
you are forced to get carpal tunnel clicking on every form with the
mouse ?
I would be willing to pay some consulting dollars to get this
resolved.

- JRE versionsWe have in our company several applications that require JRE to work.
They have been developed by different people and some require specific
versions of Java to work correctly.
Normally the applications work well individually but sometimes, when we
need to work with some of them that require different JRE versions, we
are in trouble.
How can we deal with this problem? Why last versions of JRE are not
full compatible with the previous ones?

- Beginner question about JDO best practiceDear all,
this is the first time I'm using JDO/ORM (the JPOX implementation) and
so have a question about best practice.
Let's assume we have a class "Tag" with the only property "String
name" and according setters and getters. The related table has two
columns "PRIMARY BIGINT tag_id" and "UNIQUE VARCHAR name". Note that
the column "name" is unique.
Let's further assume that we manually create some Tag objects during
application runtime. We now want to persist these objects but we don't
care if they are already persisted in the database. If this is the
case, JDO should just attach the object to the database instance. What
is the best practice to accommodate this? Do I have to manually check
every object for existence first? I would like to avoid this.
Let's say the tag "coffee" is already available in the database. I'm
looking for something which works like this:
--8<-snip->8--
Tag tag1 = new Tag( "java" );
Tag tag2 = new Tag( "means" );
Tag tag3 = new Tag( "coffee" );
// no problem
pm.makePersistent( tag1 );
// no problem
pm.makePersistent( tag2 );
// throws SQLException DUPLICATE KEY but should just attach/update
tag3 to database instance
pm.makePersistent( tag3 );
--8<-snip->8--
Thanks for any hint!

Indeed, I think the choice of "reference" to mean "pointer or null" was
a bad one. It would have been better to call a pointer a pointer, and
note that it can be null.
For the benefit of people transitioning from C or C++, it may be
necessary to note that it does not have pointer arithmetic or unsafe
conversions.

"pass by reference" (or more usually "call by reference") is a long
standing term with a meaning independent of the use of "reference" as a
freestanding term. I learned it long before I knew any language in which
one could actually have a reference. I don't see any reason why having
to learn a Java-specific meaning of reference should require people to
learn special meanings of other terms, especially when with have a
perfectly good phrase, "pass reference by value", that is only one word
longer and says *exactly* how Java behaves.

- Could you write this sound applet?As a start, consider this simple QBASIC program that generates random
frequencies:
10 frequency = 40 + 400 * RND
20 SOUND frequency, 7
30 GOTO 10
That's fine - except that it plays over the PC speaker - the one that's
just there for the happy beep - and not through the sound card and
proper speakers. You can't control volume, either.
I wonder if anyone would be kind enough to translate the above three
line program into a Java applet. I would like to see whether it looks
simple enough for me to cope with.
If it looks as if I could cope with Java, I would then learn it, and try
to program a way of generating sounds from a mathematical sequence or
formula.

You are under arrest. You have the right to remain silent. Anything

- File Persistence In the Session ObjectI am developing a Struts1.1 based application, that returns an Excel
File generated by Jakarta's POI classes. One of the requirements is
that the file be stored in the SESSION ONLY, not on the file system.
Is this even possible? Doesn't a file need to be physically present
before a reference to it can be stored in the session?
prompt insight would be most appreciated, as I'm working against a
deadline.
Thanks!

- "class not found".I'm getting the dreaded "class not found" error. I've Googled this
error and found that it's quite common, but not in exactly the way I
get it. My applets run fine on my machine, both when tested locally
via a local HTML file, and also when going to website, but gives the
"Class not found" error other machines. Anyone have any idea what
might be wrong?
I suspect it may be a codebase error, but I've tried the following in
my HTML file without success:
<APPLET CODE="moonCalendar.class"
name = "moonCalendar" WIDTH=1000 HEIGHT=350>
<APPLET CODE="moonCalendar.class" codebase="."
name = "moonCalendar" WIDTH=1000 HEIGHT=350>
<APPLET CODE="moonCalendar.class"
codebase="http://www.ckolchak.com"
name = "moonCalendar" WIDTH=1000 HEIGHT=350>
You can see if it works on your machine by going to:
http://www.ckolchak.com/astroCalendar.htm

- paintImmediately()Is there a reason NOT to use paintImmediately()? It seems to solve a

there some "gotcha" that I haven't run into yet?
Thanks

If the class somehow intrinsically is critical to behave exactly the way
you specified, including internals like representation of data and so on,
and subclasses would necessarily break this function. (Like
java.lang.Class)

Hmmm what is the meaning of intrinsically?
What will final tell about the class? Can data not be changed?
How can subclasses break this function if class is not final?

You make a class final so that it can't be extended, thus preventing other
client programmers from changing your implementation.
> How can subclasses break this function if class is not final?
A subclass can override the methods from the baseclass, that's the whole
point.

- Java Timer, swingDear Java experts,
I'm struggling with timers. I've used javax.swing.Timer in my program. But
when one doesn't have the jre installed, my program doesn't work. It then
gives a class not found exception in the browser. It only works on the sun
virtual machines which you have to download from the website like some jre.
I quess the swing library isn't supported by a lot of virtual machines. But
I'm happy about how the timer works in my program because it makes use of
the actionListener.
Is there some easy solution? Using a simple Timer like the swing version and
let it work on any virtual machine/ jre?
best regards,
Piet den Dulk (Netherlands)

- serialVersionUID.. ?Hello ,
I posted this message in the Eclpse group with no responses. I am using
Eclipse.
I resolved by defining this in my class:
static final long serialVersionUID = 0;
Now, all of a sudden, this is not working and getting error:
Syntax error on token "DETAIL_FOOTER", VariableDeclaratorId expected after
this token
Happens when I define this class var in applet or interface:
private DETAIL_FOOTER = "# detail footer";
I do not have a clue! Any one have any Ideas?

- Creating an object during runtimeI'm trying to generate an object name during run time, and then create an
object with the contents of that variable. You can see that I'm trying to
also make the object name self generating (almost, the 'y' variable isnt
being incremented yet), putting two values ('y' and 'C'). My apologies for
poor coding structure / lack of comments, but I'm am a bit lost on how to
work it out. MANY thanks in advance.Heres what I have so far:
public class testVariable
{
private String name = "";
private String New_name = "";
private int y = 2;
public testVariable()
{}
public void test(String x)
{
name = x;
New_name = name + y ;

- ANN: New XML Differencing, Updated XML Mapping in Stylus Studio 5.3
A new update for the Stylus Studio XML IDE adds a new XML Differencing
Tool, updated visual XML mapping tools and many other features. Download
a free trial of Stylus Studio 5.3 at:
http://www.stylusstudio.com/xml_download.html
Highlights of new XML Differencing Tool:
* Differencing of XML files and folders using a customizable color-coded
XML tree view
* Support for one-to-one and many-to-one XML file
* Step through XML differences node-by-node
* View differences using "split-screen" and "merged changes" views
* Expand all changes, or collapse identical XML blocks to simplify the
display
* User-configurable XML differencing settings allow you to optionally
resolve or ignore
* XML entity references and XML namespaces
More information at: http://www.stylusstudio.com/xml_differencing.html
Updates to Stylus Studio XML Mapping Tools:
Stylus Studio's visual XML mapping tools now support new split-screen
editing mode that simultaneously display fully editable views of both
the visual XML mapping diagram and the underlying XSLT or XQuery source
code which implements the visual XML mapping. You can now edit either
the source code or the visual XML mapping diagram, and see instantly the
effect their changes have - all without clicking a separate tab or
opening another editor. The automatic synchronization of both the visual
mapping diagram and the XSLT or XQuery source code views is the most
productive mode for developing XML mappings and is a great way to learn
the intricacies of XSLT and XQuery. More information at:
http://www.stylusstudio.com/xml_to_xml_mapper.html

- JNI CallStaticVoidMethod fails after N callsI have written an application in Java and C on the Solaris 10 (x86)
platform using the JDK 1.5.0_09. The Java code calls a native method
"startButtonWatcher," which then forks, the parent process returning,
and the child process initiating an event loop that calls a static
method, "sendButtonEvent," on a Java class "ButtonWatcher."
The problem is that on the 65 invocation, the CallStaticVoidMethod will
hang. There is no core file or pid log file produced. (it will also
hang for CallVoidMethod as well if I remove the static declaration in
ButtonWatcher.)
I have also added a main() function to the C code so that it can be
compiled and run as an executable rather than a library file loaded
from Java, and the the same loop will be fine, the Call*Method call
being exected forever (or over a million times at least). The only
difference in the code is the JVM--in the sharable library, it uses the
JVM of the class that calls the native method, and the standalone has
to create its own. What could be the problem? Thanks!

Does this mean you still accuse me of hacking OpenOffice.org's mailing
lists? What a hoot!

- url rewriting when the url contains parametersHi,
I am trying to maintain sessions by doing URL rewrite. Things were
working fine till the URL did not contain any parameters. The URL that
I have now is of the form:
http://myurl?id=1&user=null and on doing a sessionID append it becomes
http://myurl?id=1&user=null;jsessionId=xyzw..
Things still get authenticated but now when I try and get the value of
user I get passed the whole string after user= and not just null.
What is the right way to append the sessionID? Btw, I am using the URL
to connect to a servlet from a j2me client.
Thanks,
Gaurav
