Error starting J2EE server !!!!

I've installed the j2ee server on my computer (i'm using jdk1.3.1.02 with j2sdkee1.3.1). it was running fine last week, but when I ran "j2ee -verbose" this morning, I was getting the error/stack trace (shown below). I don't have another instance of j2ee running as the error message claims, (I even reinstalled j2ee and am still getting the same message). What can I do? Any suggestions? What could possibly be making j2ee think that there is another instance of itself running? Thanks.

Perhaps you didn't try the simplest thing, I don't know. Try to write j2ee -stop. You never know. Good luck.

你启动了两个j2ee如果你是NT请查看你的服务启动情况。

Try to see if the port number 1050 (default) one is still in used.

Use the command 'netstat' (on linux and windows) to see if a connection is established

on this port. This port is the listen port used by the j2ee server.

If you see that the connection is established and your j2ee server is stopped, perhaps

it is due to a delay time needed to free the connection (a problem that I faced on my linux

system).
