How to open a messagedialog in a RAP application [message #1712481]

Hello guys. Smile

I'm trying to open a messagedialog in a RAP application by using this code

MessageDialog.openInformation(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(), "Test","Testtitle");

My problem seems to be, that I can't get a proper shell reference.
I'm new to rap and just edited the "hello world" example delivered by eclipse. What steps do I have to do to get this to work?
I did this steps:
1.) New plug-in project
2.) Template RAP Hello World
3.) Add org.eclipse.ui.workbench_3.107.0.v20150825-2206.jar
4.) Execute MessageDialog.openInformation as stated above

When I use the to String function I just get an empty array, but the debugger shows an ID.
I also get an error saying "java.lang.ClassNotFoundException: org.eclipse.ui.testing.TestableObject" when my application crashes.
Did I include a wrong jar?
Do I need to include another jar?
Might this be a problem because I use the simplified entrypoint?

public class BasicEntryPoint extends AbstractEntryPoint

Any help is greatly appreciated, I'm really stuck here. Sad

Hi, the correct shell comes from the current Display.
So :

Display.getCurrent().getActiveShell();

Thanks for your reply!
This results in the following error:
Quote:

java.lang.NoClassDefFoundError: org/eclipse/core/runtime/IStatus.

I'm a RAP noob and just downloaded the complete bundle with eclipse.
Whenever I add a jar I get the next class not found error.
Is there a way to search the needed jars automatically?

//edit:
I solved the problem by copying and adding the jars from the mail example.
My new error is:
Quote:

java.lang.UnsupportedOperationException: Display#sleep() not supported in current operation mode.

This seems to be a never ending story for me. Razz

//edit2:
Adding dialog.setBlockOnOpen(false); to my jface dialog did the trick.
Thanks for your help!

I'd say something is wrong with your target. RAP works with bundles and plug-ins. You don't add jars to your project but to your target (you should have a .target file or go to WIndow>Preferences>PDE>Target Platform). Then you will be able to add that in your dependencies in your MANFIEST.MF plug-in file.

By the way don't use org.eclipse.ui.workbench. The org.eclipse.rap.ui.workbench replaces it. I think that's where your errors are coming from.

Hi,

I hava the same error as Martin.

I confirm that I use org.eclipse.ui.workbench.
But I cannot find the replacement plugin you are proposing : org.eclipse.rap.ui.workbench...

I use eclipse mars.
Any suggestion?

Thank you.

I add to my previous response that I insalled the rap tools from http://download.eclipse.org/rt/rap/tools/3.1

I still not have the org.eclipse.rap.ui.workbench plug-in...

Another information of my current work is that I am updating a working dev environement from eclipse helios to mars and I am not an OSGI expert.

One of the required bundle (in MANIFEST.MF) was org.eclipse.ui.
So when I remove org.eclipse.ui.workbench he is not happy!

Does what you propose mean that all org.eclipse.ui is "deprecated"?

Thank you!
