Debugging weblogic 9 2 with Intellij 6.0.1 build 5784

Debugging local weblogic 9.2 (with JSF), I am getting this message when Intellij starts up Weblogic:

weblogic.application.ModuleException: Context path '/cdt-complaints' is already in use by the module: cdt-complaints.war application: appsdircdt-complaints_war

What am I doing wrong?
