Hi
Just try the following steps:
1. Check the Container Logs..They will tell you where you are going wrong.Tomcat logs directory is present in <TOMCAT-INSTALL-DIRECTORY>/logs
2. ARE you using a script to start your container or is does it start as a service.If Your OS is Windows you can use the standalone installation of Tomcat that runs as a windows service.
Anyways that doesn't have any relationship with the problem and its up to you tco choose.
3.It might be possible that you might be have conflicts with the Port 8080.
Long time back i faced the same problem.In case nothing works just open the server.xml file located in <TOMCAT-INSTALL-DIRECTORY>/\conf path.Change the Port to some other value say 8111. and try restarting Tomcat..
I hope this works for you.
You can use the commmand netstat -ao on the command line to check the ports you are listening to .
