[xwiki-users] Xwiki & OC4J in Oracle App Server 10.1.2.2

Has anyone got any version of Xwiki running under OC4J running on Oracle AppServer 10.1.2.2 (Oracle App Server 10gR2)? We can't upgrade to 10.1.3 due to limitations of Oracle Portal 10g. When I deploy the app under a new OC4J container I get: java.lang.UnsupportedClassVersionError: org/exoplatform/container/PortalContainer (Unsupported major.minor version 49.0) at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:539) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:123) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].util.OC4JSecureClassLoader.defineClassEntry(OC4JSecureClassLoader.java:172) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].naming.ContextClassLoader.defineClass(ContextClassLoader.java:1179) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].naming.ContextClassLoader.defineClass(ContextClassLoader.java:1065) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].naming.ContextClassLoader.findClass(ContextClassLoader.java:404) at java.lang.ClassLoader.loadClass(ClassLoader.java:289) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].naming.ContextClassLoader.loadClass(ContextClassLoader.java:143) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302) at com.xpn.xwiki.web.Utils.prepareContext(Utils.java:203) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:87) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java:65) at com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:117) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:673) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:340) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:830) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].server.http.AJPRequestHandler.run(AJPRequestHandler.java:228) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].server.http.AJPRequestHandler.run(AJPRequestHandler.java:133) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.2.0)].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:186) at java.lang.Thread.run(Thread.java:534) I assume it's incompatibility with java/oc4j versions...
