Import package problem in GWT

Question

I'm developing an app using GWT Eclipse plug-in. (I'm also using GWT Designer but I don't think the problem is here). Previously when I wanted a java application to communicate with a web service I created, I produced the "skeleton" classes from the WSDL url using Sun's wsimport tool. Then I would add the classes generated to a class folder in my Eclipse project. All worked well.

However this doesn't seem to be working with GWT. I have these:

VideoTutorialServiceService service = new VideoTutorialServiceService();
VideoTutorialService port = service.getVideoTutorialServicePort();

and I have VideoTutorialServiceService and VideoTutorialService underlined in red, the error saying videotutorialservice.VideoTutorialServiceService can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly.

.... I googled about it but I got confused. I'm a beginnier in GWT. How can I resolve this please?

Thanks and regards, Krt_Malta

The problem probably does come from the GWT Designer. See these discussions on GWT Google groups : GWT Designer errors in Eclipse and Cannot found source in GWT Project.

You can ever uninstall GWT Designer plugin ^^ or change the settings :

In WindowBuilder > GWT > Builder
Uncheck the Check for "client" classpath option

Wow, that was non-obvious! Thank you, this really helped. :) – Don Branson Mar 23 '11 at 02:49

Check the capitalization of the VideoTutorialServiceService enclosing class. If you copied/pasted it verbatim then it's looking for videotutorialservice.VideoTutorialServiceService instead of VideoTutorialService.VideoTutorialServiceService

Are VideoTutorialServiceService etc. wsimport generated files? If yes, then they won't work with GWT.

GWT doesn't support all java classes. It just supports a sub-set that makes sense in the javascript world. Remember that GWT is essentially a java -> javascript compiler, so you can't take any java code and expect it to run properly in javascript.

I also had a similar problem, I have a GWT 2.0 app which I have integrated it with spring-security and hibernate. Before I installed GWT Designer it worked okay. Then after installing it, I had this error on Eclipse org.springframework.orm.hibernate3.support.HibernateDaoSupport can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly. Then I tried uninstalling GWT Designer and the error was gone. I don't know if this is a bug with GWT designer because In my eclipse class path, I had added the appropriate jar files.
