Hi Peter, I'm using JBoss 5.0 RC 2 (JDK 6) on Windows XP. I'm deploying a JSF 1.2 compatible app written in Oracle JDeveloper using Oracle's ADF framework (JSF 1.2 compatible). I srarted by copying the required ADF libs to the JBoss \default\lib directory. I then dropped the exploded ear/war file into the \default \deploy directory. The auto-deploy starts ansd eventually I get the following - 2008-12-01 15:18:13,753 WARN [org.jboss.detailed.classloader.ClassLoaderManager] (main) Unexpected error during load of:oracle.security.jps.principals.JpsRole java.lang.OutOfMemoryError java.lang.NoClassDefFoundError: oracle/security/jps/principals/JpsRole This class is contained in jps-api.jar, which I have already copied over to \default\lib.
