          Hi Kumar
          I have installed BEA Weblogic through Webgain Studio. I remember to have chosen to install Weblogic with the Service Packs.
          How do I know if I have installed the correct service packs.
          I still have this problem that 'main not found' in a startup servlet.
          Thanks
