Start up errors with Oracle Weblogic Server plugin for Eclipse Luna -


we have existing project built using eclipse indigo , relevant weblogic server plugin. done 4 years , trying migrate eclipse luna. project imports , works fine until add weblogic server tools plugin eclipse luna or lower version , restart eclipse. starts complaining "an internal error occurred during"

  • building workspace
  • initializing java tooling
  • validating project
  • appxray indexing (this fix disabling windows->preferences->oracle->appxray)

the resulting application ear deployed on oracle weblogic server 10gr3. resolving issues highly appreciated. know problem oracle weblogic server tool plugin eclipse luna moment remove not see errors. have tried cleaning .metadata , relaunching eclipse still error starts ocurring.

update: below exception stacktrace found .log file within .metadata. not able understand log. can help?

after experiencing problem on our team thought post solution found.

this occurred when moved luna based ide mars sr1 release. tracked down file in source control.

.settings/oracle.eclipse.tools.weblogic.syslib.xml

once deleted eclipse start happily, , go. 1 developer tracked issue down single line inside file.

<module id="javax.persistence" javadoc="http://java.sun.com/javaee/5/docs/api"/>

if single <module> line commented out eclipse oepe error goes away. fyi, won't see error when importing project, on every restart after project has been pulled down.
