Build: wtp-sdk-I-I200612070955-200612070955 Repro: -Create a dynamic web project (did not associate with an EAR in this case) -Open Properties->J2EE Module Dependencies->Add Variable -Create a new cp variable pointing to some Jar on your system What works: -The following entry will be successfully added to the component file: <dependent-module deploy-path="/WEB-INF/lib" handle="module:/classpath/var/JSR173_API"> <dependency-type>uses</dependency-type> </dependent-module> Intermittent problem: The first time I tried this, I hit the following problems (note: these may have been due to something unrelated to the variable entry...) -I was unable to resolve classes in this jar successful for the project. -On re-opening J2EE Module Dependencies, the variable entry was not listed -An attempt to export the WAR file for the project failed with the following error: ... org.eclipse.core.runtime.CoreException: Extended Operation failure:

After restarting Eclipse and re-adding the cp variable dependency, classpath visibility and WAR export worked correctly, however, when the J2EE Module Dependencies UI was reopened the cp variable entry is listed as unselected, so the user cannot remove it.
I am closing this as fixed- the replacement of the J2EE Module Dependencies with the Deployment Assembly addressed a lot of issues- I believe this was one of them. If this is still an issue, please reopen this.
