Yeah. Thx very much. Problem solved. I had the Sun/SDK on my system classpath, because i installed it before the normal jdk 1.5. I changed the system classpath to my jdk installation, then it worked. Thought i was said that Java EE 5 installation comes along with a complete jdk 1.5 version, but it seems as if you must install both seperately.... this confuses me.....
