      Hi Nir,

      We also had same problem but no we won't. Check ur config on SLD again and the try to the test connection from the http://localhost:4444/webdynpro ( WAS 6.4 )server.

      If this connection is OK then deploy some small application n see.

      Is ur's JCo connection working for J2ee application?

      Arnigs
