RE: Tomcat and openjpa javaagent
Try putting that jar into Tomcat's bin directory instead. It must be available to the system classloader, not Tomcat's common classloader. This had no effect. Tomcat in startup script sets the CLASSPATH variable to $CATALINA_HOME/bin/bootstrap.jar, so i tried to modify it in catalina.sh to $CATALINA_HOME/bin/commons-lang-2.3.jar. Now tomcat starts, but when launching my application I'm getting more exceptions, first: Caused by: NoClassDefFoundError: javax/persistence/spi/PersistenceProvider I've added geronimo-jpa_3.0_spec-1.0.jar and then I got Caused by: java.lang.ClassNotFoundException: javax.transaction.Synchronization so it asks me for a bunch of libs from my WEB-INF/lib directory. And finally JVM says it is unable to load classes from my app. So i think it is not a right way to fix my problem) Hoping for your help! -- View this message in context: http://old.nabble.com/Tomcat-and-openjpa-javaagent-tp28506406p28509633.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

geronumolibs need a jee container to function otherwise the classes will never be instantiated.

Re: Tomcat and openjpa javaagent
Well, I set openjpa-all-2.0.0.jar as javaagent, and all startup exceptions are gone. Still there is no runtime optimization available, an exeption is being throwed when accessing the database: Caused by: openjpa-2.0.0-r422266:935683 nonfatal user error org.apache.openjpa.persistence.ArgumentException: This configuration disallows runtime optimization, but the following listed types were not enhanced at build time or at class load time with a javaagent: -- View this message in context: http://old.nabble.com/Tomcat-and-openjpa-javaagent-tp28506406p28511183.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

According to the advice from http://openjpa.208410.n2.nabble.com/openjpa-javaagent-enhancement-with-tomcat-td5029993.html this thread I switched to build-time enhancement, and it worked for me. -- View this message in context: http://old.nabble.com/Tomcat-and-openjpa-javaagent-tp28506406p28517128.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
