WebLogic

A version of the ANTLR library that ships with WebLogic 11g conflicts with the version required by Orbeon Forms. To run Orbeon Forms on WebLogic 10/11g, you need to instruct WebLogic to let Orbeon Forms use the version of ANTLR that ships with Orbeon Forms. You can do this in the WebLogic EAR descriptor, which means you need to encapsulate Orbeon Forms in an EAR before you deploy it:
1.Create the following directory structure in a temporary directory:
 orbeon-ear
     META-INF
         application.xml
         weblogic-application.xml
     orbeon
Populate application.xml with:
 <?xml version="1.0"?>
 <j2ee:application xmlns:j2ee="http://java.sun.com/xml/ns/j2ee">
     <j2ee:display-name>Orbeon Forms</j2ee:display-name>
     <j2ee:module>
         <j2ee:web>
             <j2ee:web-uri>orbeon</j2ee:web-uri>
             <j2ee:context-root>/orbeon</j2ee:context-root>
         </j2ee:web>
     </j2ee:module>
 </j2ee:application>
Populate weblogic-application.xml with:
 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE weblogic-application PUBLIC
     "-//BEA Systems, Inc.//DTD WebLogic Application 8.1.0//EN"
     "http://www.bea.com/servers/wls810/dtd/weblogic-application_2_0.dtd">
 <weblogic-application>
     <prefer-application-packages>
         <package-name>antlr.*</package-name>
         <package-name>org.apache.commons.lang.*</package-name>
         <package-name>org.apache.commons.fileupload.*</package-name>
         <package-name>org.apache.lucene.*</package-name>
     </prefer-application-packages>
 </weblogic-application>
2.Uncompress the orbeon.war into the orbeon-ear/orbeon directory you created in step 1. After this, you should have a directory orbeon-ear/orbeon/WEB-INF.
3.Deploy the orbeon-ear directory. If you are running WebLogic in development mode, you can move it to user_projects/domains/base_domain/autodeploy.
4.Optionally, you might want to change where the orbeon.log is stored. You define the location of the file in WEB-INF/resources/config/log4j.xml, in the SingleFileAppender. By default the location of the file is defined as ../logs/orbeon.log. If you start WebLogic with user_projects/domains/base_domain/startWebLogic.sh, the log will be located in user_projects/domains/logs/orbeon.log.
