my server is J2EE1.2.1
when i write the program and it works fine on my machine, but when my partner runs the program (i keep running), there is an error 500 message shown:
Internal Servlet Error:
"javax.servlet.ServletException" and
"java.lang.NullPointerException" are thrown
then i redeploy the program and let only my partner runs it, it still works fine, but after i also run the program (my partner keeps running), the message shown again, it seems that my program can't support multi-user. Would anyone help me?
Thx a lot
