Hello, I succeeded installing mapviewer 10131 on jBoss 4.0.5, although with a limitation I need to solve. Can't reach the new Mapviewer Home html application to configure cache because Jboss doesn't understand jspx. Used succesfully the AdfInstaller from OTN after copying the 36 lib files to JBOSS_HOME/server/default/lib. [As described in http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content... But can't run /mapviewer/faces/home.jspx yet. Next I post errors for before (a) and after (b) having deleted folder jboss\server\default\deploy\jbossweb-tomcat55.sar\jsf-libs [Understood this as equivalent step from doc "JBoss Deployment Notes" although written for version 4.0.3] Also tried to delete folders tmp, log and data, but get same error.
