I am using netbeans to develop a struts application. usually, i can run the application without having to restart tomcat, i guess netbeans does it by itself, anyways lately, tomcat keeps complaining that the port number is already in use. It runs fine the first time, but when i run the app again it complains, also shutting down the server takes a long time. I have changed the port from 8085 to 8032 to 8023 in all cases it works the first time but not the second. even if i try to go back to port 8085 it will still complain that its in use.

all this happened after i install oracle XE on my machine. Don't know what exactly is the connection.

Please help and thanks in advance

Make sure there's no other copy on the machine. In Windows, ports can be hung onto too, so you may need to reboot

I do have two copies of tomcat, the tomcat that is giving hte problem is the one that is bundled with netbeans, but i am running just one right now. and this was not a problem before.

If i reboot, same thing works fine the first time but not the second.  

Thanks

Run a netstat command on your command-prompt to see which ports are being used.

That's a completely different issue - a classpath one

sounds like you are starting tomcat when it has already running when u attempt to start it.
make sure you shut it down fully before restarting it.

possible solutions
* oracle XE is using the same port with tomcat change one of them.

* while trying to stop server it may not be stopped. This means your bundle tomcat config. may be corrupted. reinstall nb. some times netbeans cant stop tomcat. look at taskmanager if there is a cmd instance there. tmcat probably is running.
