OS X: launcher inside .app [message #723454]

For AWT/Swing applications one usually uses the JavaApplicationStub to launch. For SWT applications we need to use the VM option -XstartOnFirstThread. According to my tests this seems not to work when using JavaApplicationStub and passing this option in the Info.plist (tried similar to the -Xmx option). Hence I'm now using a plain shell script.

Is that the correct way of launching an SWT application on OS X?

I have *no* experience with MacOS and SWT, but does this possibly help:

Unfortunately, no, because it looks like AWT related.

Maybe this link helps:
http://eclipse.org/swt/macosx/

Disclaimer: I have never tried it myself.

Cheers,

That's what I'm currently doing, but I'm not sure whether this still is the officially suggested way to do it, especially because Apple promotes the JavaApplicationStub - at least for AWT/Swing.

Eclipse provides a way to create a Mac application bundle from a Java project.
Right click on project > Export > other > Mac OSX Application Bundle. In the wizard page, select the checkbox "Use SWT" and fill in the other details. The app bundle is created automatically.
(Sorry, I didn't remember this before Sad

Unfortunately, there is no "other" category visible in my Export wizard. I've downloaded "Eclipse IDE for Java Developers" and created a small test project with SWT code.

I tried the "Eclipse IDE for Java Developers" 3.7.1 version and the export wizard does have the other category (tried File > Export... )

Sorry, I've downloaded a fresh copy of eclipse-java-indigo-SR1-win32.zip and when I invoke File -> Export there is no Other node. Maybe you have installed some additional plugins I don't have?

This is a mac only feature, can you try with the mac-cocoa eclipse download?

You are right, this feature is available in OS-X-Eclipse. Unfortunately, the result looks very basic: I've got just following directory structure

Test.app/
[-] Contents
   [-] MacOS
   PkgInfo

That's it. Nothing in the MacOS directory, no Info.plist, no library (though I told it to use my launch configuration).

I exported a SWT project as a Mac application and it got created fine with Info.plist and the jars.

directory structure using ls -R Test.app
-----------------
Contents

Test.app/Contents:
Info.plist MacOS PkgInfo Resources

Test.app/Contents/MacOS:
JavaApplicationStub

Test.app/Contents/Resources:
Java

Test.app/Contents/Resources/Java:
jar_0.jar org.eclipse.swt.cocoa.macosx_3.8.0.v3800d.jar
--------------------

-You need check the "use SWT" checkbox and provide the correct run configuration.
-In the "Classpath and Libraries" page in the export wizard lists the jars & folder that will be added to the classpath.

First, thanks for your continuing effort. To shorten the thread, could you please post the content of the generated Info.plist (assuming that the application starts fine)? Thanks in advance.

Attached the Info.plist here...
I'm still curious why the export mechanism is not working for you?!

Thanks. How to add the command line parameter -d32, too?

I've tried again. Please see following screenshots.
index.php/fa/4395/0/

Please note following bugs:
- the "Use this launch configuration" combobox is too narrow
- selecting the item from the "Use this launch configuration" combobox does not pick any main class or classpath entry
- clicking the "Search" button right beside the Main class input field does nothing
