I applied fixpack 11 to my WAS 6.1 installation on Windows 2000 Server. The update proceess ran OK. When I restarted the server, it fails:



java.lang.ClassNotFoundException: com.ibm.ws.management.tools.WsServerLauncher

at java.net.URLClassLoader.findClass(URLClassLoader.j ava:492)

at com.ibm.ws.bootstrap.ExtClassLoader.findClass(ExtC lassLoader.java:132)

at java.lang.ClassLoader.loadClass(ClassLoader.java:5 61)

at com.ibm.ws.bootstrap.WSLauncher.main(WSLauncher.ja va:239)



Nothing is written to the logs.



I have attached the update log created by the Update Installer.



Any idea what is wrong?



Thanks In advance.
