Problem with RPC service support

[nopalot]

Happy 2008 and thanks for the great work!

When creating a new RPC Service, the async service interface is not created. Also, adding a method to the service interface does not update any other files.

That generally means that your project is not configured correctly.

How was this project created? Any exceptions in your Eclipse ".log" file?

Hi Eric,

thanks for the quick response!
I've created the project with the following commands:

projectCreator -eclipse GwtTest -out GwtTest
applicationCreator -eclipse GwtTest -out GwtTest com.domain.client.GwtTest
i18nCreator -eclipse GwtTest -out GwtTest com.domain.client.GwtTestConstants
junitCreator -junit /home/nop/bin/junit3.8.2/junit.jar -eclipse GwtTest -module com.domain.GwtTest -out GwtTest com.domain.client.test.GwtTestTest

Here is the content of the eclipse log file:

I've noticed that version 3.0.0 of GWT Designer does not cause any entries in the eclipse error log. So the above messages are specific to todays (01.01.2008) build. But regardless if i use version 3.0.0 or 3.0.1, the behaviour is the same.

Do you have any ideas what went wrong?
Thanks for your support!

[Eric Clayberg]

Please see the docs for how to create a GWT Designer project.

GWT Designer does not provide any compilation assistance to projects that it knows nothing about.

[nopalot]

Thanks for pointing to the docs!
Rightclicking the Project and selecting "Google Web Toolkit->Convert project into GWT project" fixed it.
Thanks again!
