Running SWT application outside Eclipse [message #464564]

I'm trying to create a redistributable jar file for an application I am
working on. The application uses SWT for the grapical interface. I am able
to run the jar file using the java -classpath
swt.jar;helloworld.jar -Djava.library.path="C:\SWT" helloworld command-line
parameters, but when the application starts, I don't get any text on the
buttons, I don't get any text in a list, and I don't get any images or text
on CLabels that are part of a sub-class of composite. The program works fine
within Eclipse. Any ideas of how to get this to work outside of eclipse?
P.S. The library is complete.

you use any i18n text and images from swt plugin, probably
this text/images isn't in swt.jar - you have to find where they are

I can't even get just text to display on a regular button though. How
could that not be a part of swt.jar? This is on the windows platform by
the way.

Nevermind. I read a post from earlier that solved my problem. Running
with javaw.exe instead of java.exe solved my problem.

But the guru-level question still remains: In similar (os version and java version) machines or pcs, on some of them 'java MyClass' brings the texts visible while on some others its necessary to 'javaw MyClass' in order to get the Label and Button texts visible.

What may be happening here is that for java, people have added a manifest
file (see http://eclipse.org/swt/faq.php#xpthemes) but not for javaw. When
they switch from java to javaw they are also switching from using version
6.0 of the common controls dll to version 5.0 (with the manifest files you
actually run a different version of the OS level controls).

It would be useful to know 1) Do you have a manifest? Is it for java or
javaw? 2) What Windows skin are you using? Is it the default Windows XP
Style or have you downloaded something else?

I do not see a bug report entered for this problem. Can someone who is able
to recreate the problem please enter a bug report against Platform SWT?

I'll have to check this, my experience is of three WinXP's and three Win2000's and the result was: In two xp's and one 2000 'java MyClass' brought the Label and Button texts visible and in on xp and two 2000's only 'javaw MyClass' resulted with Label and Button texts on the screen.

The SWT- and Jface-textbooks I have read fail to make any mention of javaw.exe.manifest!

I noticed that for example Azureus does have the manifest.

Is it so that javaw.exe.manifest -- it's lack or existence -- changes the behaviour of 'java MyClass'?

The manifest file affects which version of the Windows Common Controls is
used by SWT to create the native widgets.
