Hello. We have XWiki 1.2.1.7160 running under OAS 10.1.2.0.2 and database Oracle 9.2.0.6 on Linux Centos 4.4 OAS 10.1.2 is only certified with JDK 1.4 but you can change the JDK of a OC4J instance editing $ORACLE_HOME/opmn/conf/opmn.xml configuration file and specify its location in the <java-bin> element in the correct <process-type> section of xwiki OC4J instante. <process-type id="xwiki_oc4j" module-id="OC4J"> <module-data> <category id="start-parameters"> <data id="java-bin" value="/myjavalocation/jdk1.5/bin/java"/> </category> </module-data> </process-type> See http://download.oracle.com/docs/cd/B15904_01/web.1012/b14011/diagnosis.htm#… We don´t test it in deep, but XWiki starts and we can browse correctly.
