Has anyone found solution to this specific issue?
I've had some issues with Java EE Module dependencies as well. It seems that what ever I do the list is empty or says that "Selected module is not referenced by any EAR or Dynamic Web modules". How ever the module is referenced by Dynamic Web module. Am I missing something? has my workspace been corrupted (would not be the first time)? Am I just asking stupid questions?

Regards,
JP

Hi.

I have a problem related to this. When using maven-eclipse-plugin 2.8 to generate wtp-2.0 config for a multi-module-workspace (webapp depending on projects in the same workspace) I get the project references I want (classpath is updated with a project reference) but Java EE module dependencies for my webapp are not updated and when I start Tomcat 6 some classes cannot be found. Now I wonder if there is any file in eclipse (WTP?) which should have been updated. I can do the update manually and it works fine but I cannot find out how my update changes settings in the eclipse project/workspace. If I know where this setting belongs, I can start searching for a solution in maven-eclipse-plugin but before that, I do not know where to start. Any help would be appreciated.

Regards, Niklas

For dependent module to be recognized in WTP, you have to enable WTP not only in the WAR module but also in all dependent JAR modules, like this:

	      <plugin>
	        <artifactId>maven-eclipse-plugin</artifactId>
	        <configuration>
	          <wtpversion>1.5</wtpversion>
	        </configuration>
	      </plugin>
