Hello World Swing Client not showing up? [message #805829]

Hello.

I just downloaded and started the current release of Eclipse Scout. I use a Macbook Air with Lion and Java 6.

I tried to get started with the Hello World tutorial.

Server and SWT client work fine, but the Swing client does not show up. It starts and is running. No error messages or exceptions. Nevertheless, the client does not show up anywhere... There is also no seconds Eclipse / RCP starting as it is when I start a SWT client.

The console output of the client is:
2012-02-24 08:15:52.358 java[598:407] [Java CocoaComponent compatibility mode]: Enabled
2012-02-24 08:15:52.359 java[598:407] [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000

The server does not have any console output.

Any guess? Do you need more details?

Best regards,
Kai

This is strong related to bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=212617

Basically on macosx swt must be started on first thread, swing/awt must be started on second thread.

For swing to work, the IDE must be started on second thread.
Unfortunately eclipse ties the -ws switch to this behaviour.

Following works for me on a MacBook Pro with Lion and Java 6 and eclipse 3.7.1:

1) Edit the eclipse IDE(!) eclipse.ini (Right click on eclipse app "Show Contents" and in the folder MacOS there is the eclipse.ini)
Change -XstartOnFirstThread to -XstartOnSecondThread

2a) Edit the run configuration for your application:
In the "Arguments - Program arguments" remove the -ws ${target.ws} switch and add --launcher.secondThread

2b) Edit the *.product configuration for your application:
In the "Launching" tab in the "Launching Arguments" section in the "All" and "macosx" tabs remove the -XstartOnFirstThread option and (eventually) add the -XstartOnSecondThread

I know, much to do, buit in the end it works. Unfortunately there is not yet an easier solution since eclipse ide does not know upfront whether it should start a core native ui such as swt or a secondary ui such as awt.

Thanks for this answer, because it is also something I am interseted in (Mac OS X 10.5).

I will give it a try.

Thanks for the quick answer and explanation. At least, there is a workaround! Smile

did it work?

here a summarized (more comprehensive:-)) version:
1) The IDE eclipse.ini (as i re-checked it) must not necessarily be modified.
2) Start the IDE and go to the product configuration
3) Run/Debug the product, immediately stop it.
4) go to Run... / Debug... menu in eclipse IDE and remove the program argument -ws ${target.ws}
5) Start again.

For production environment:
The my_application.ini (in the my_application.app) typically contains the following

--launcher.secondThread
-vmargs
-Xms64m
-Xmx256m

This can be done by modifying the product configuration:

   <launcherArgs>
      <programArgsMac>--launcher.secondThread</programArgsMac>
      <vmArgs>-Xms64m
-Xmx256m</vmArgs>
   </launcherArgs>

This post gives me the occasion to try SWING (For the moment I was focusing on SWT).

The method you describe do not work for me...

I found also a VM argument specific to the mac:

-Dorg.eclipse.swt.internal.carbon.smallFonts

It was probably added by the SDK. I tried with and without it...
Is this argument needed ?

In some cases I got the lines:

[Java CocoaComponent compatibility mode]: Enabled
[Java CocoaComponent compatibility mode]: Setting timeout for SWT to 0.100000

and sometimes not.

There is also a short guide on how to use swing client on Mac OS X in the Minicrm Tutorial: New_Eclipse_Scout_Project.
At the end of chapter "Create a new Eclipse Scout project" you can find some hints. Do they help?
