Grails 2.0 basic warfile doesn't run on Weblogic 10.2

Created a basic 2.0 grails app in spring source tool suite 2.8.1 with grails and groovy plugins. Configured for grails home 2.0.0 and groovy 1.8.3. Using JDK 1.6 with compatibility set to 1.5.
War creates fine - but then 2 issues when I go to deploy on weblogic.
1. War Doesn't include the needed standard.jar but I think there's another Jira on this.

• Added this using a copy command in buildconfig.groovy.
  2. Get exceptions trying to create the pluginManager from applicationContext.xml.
• Not the same problem as reported for weblogic 10.3 in previous version of Grails... I followed the suggestions to create a weblogic.xml file with context root, rename sessionid cookie, and specify prefer-webinf-classes. Same issue. Log file attached.
