I try to execute my SWT application under Mac OS X and i have the following
error:

org.eclipse.swt.SWTException: Invalid thread access
at org.eclipse.swt.SWT.error(SWT.java:2860)
at org.eclipse.swt.SWT.error(SWT.java:2783)
at org.eclipse.swt.SWT.error(SWT.java:2754)
at org.eclipse.swt.widgets.Widget.error(Widget.java:554)
at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:305)
at org.eclipse.swt.widgets.Control.isEnabled(Control.java:1218)
at org.eclipse.swt.widgets.Display.mouseProc(Display.java:2517)

This application is deployed with JavaWebStart and works fine under Windows
and Linux.
I pass in my JNLP file JVM argument -XstartOnFirstThread which could
resolved the problem but it's the same thing...

Could someone help me please??? i don't understand how to resolve this
problem.

Thanks, Tom.

Do you create multiple Display objects in your application? Mac OS X will
only support one.

Thanks for your response Veronika,

diaplay is creating using this:

Display display = PlatformUI.createDisplay();

It's the only one display i create.
After that i call shell.getDisplay() or Display.getCurrent() for use the
display...

The problem seems quite odd. Do you have an example that you can post here
that shows the problem?

My application is too big to post here and not now online but i found
another RCP application deployed with JavaWebStart which have exactly the
same problem like mine and online so you could test it if you want to see
exactly the problem (note that like mine this application works fine under
Windows - i haven't try it under Linux - ).

Thanks for your help.
Best regards.
