More problems starting J2EE

I'm trying to run J2EE on a Windows NT machine. I've set up JAVA_HOME and J2EE_HOME environment variables and set up my PATH to include %JAVA_HOME%\bin and %J2EE_HOME\bin. I know these are correct because I can run javac and j2ee from the command line. My CLASSPATH includes "%J2EE_HOME%\lib\j2ee.jar; %JAVA_HOME%\lib\tools.jar;". I think that this is right because the error messages below suggest j2ee is finding j2ee.jar.
However, I'm getting a couple of different errors when I do "j2ee -verbose" at the command line. Yesterday I got the following (sorry it got a little truncated on the right, but I think it's only missing line numbers):
C:\>j2ee -verbose
J2EE server Listen Port: = 1049
Naming service started: :1050
Published the configuration object ..
Binding DataSource, name = jdbc/Cloud
DB;create=true
java.lang.RuntimeException:

J2EE server reported the following error:
Error executing J2EE server ...
Today, I'm getting this error:
C:\>j2ee -verbose
J2EE server Listen Port: = 1049
java.lang.RuntimeException: Could not initialize j2ee server. Possible cause could be another instance of the server already running.

I didn't change any of the environment variables between yesterday and today. As far as I know, there is no other j2ee server running on my machine.
Any ideas? Thanks!

iTS VERY CLEARLY STATED THAT THE SERVER INSTANCE IS ALREADY RUNNING.
GOTO CONTRO PANEL->SERVICES AND SEE WHETHER THE SERVER IS INDEED RUNNING, SHUT IT DOWN AND THEN DO THE REST
OR ON THE CMD PROMPT DO NETSTAT -N TO SEE WHETHER THE PORT THAT U HAVE MARKED AS THE SERVER LISTENER IS ALREADY BUSY

P.S: In case u still have problem please post or mail at g_sahil@usa.net

Thanks for your response. I've looked in Control Panel->Services, but I didn't see anything that looked like a the j2ee server. Does it have a non-obvious name? My netstat output doesn't show anything on port 1050, which is where the naming server started yesterday. I haven't yet gotten into j2ee and so I haven't done anything about manually setting up ports--whatever is happening is default behavior. Is there something I need to do that wasn't in Sun's installation instructions?

Hi Jess,
I am sorry but i am a Weblogic guy and so i can't say much bout the j2EE server anomalies. I guess if my earlier reply did not help u then theres not much that i can do.
Am Sorry

p.s: Make sure that u did not start J2EE Server as a Windows service coz then if u'r m/c boots then that service is started but that is shown in the services. If nothing helps then u can boot the m/c and start again

Thanks Sandy. Ultimately, this turned out to be a probable networking problem. The startup procedure crashed while trying to startup the IIOP listener for CORBA. I'm on an NT workstation on a network, and it looks like the default port for the listener is unavailable because of the way things are set up. I'm still working on a solution, but I did get j2ee up and running on a Win98 machine with no problem.

good for you
Bye

Hey sandy, this has happened to us when other apps. (ex: Outlook) somehow use the 1050 port... you might wanna use j2ee on another port o change your app.....

Yep - I've had a few problems in the past with applications like Outlook and Yahoo Messenger. A reboot followed by starting up the J2EE server before any other apps usually sorts it out.

Hi,
If I'm not wrong, running ICQ will cause some problem starting J2EE-RI server.
Cheers.
