Well the way of detecting where locking happens worked quite well, display the class-names of the objects where locking happens using Bea's JRA and have a look in netbeans profiler where calls to these class happen. It turned out that all the Vector stuff was happening inside of ant, I was using the ant version of tomcat for testing ;) It looks like all the locking happens at startup, at least this is what I guess. So no need to worry :-) Thanks for your patience, lg Clemens --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
