Tomcat server not running in eclipse with project

I have one basic web project using spring in eclispe. I have installed tomcat v7 .

Now when i sta开发者_开发百科rt server alone , without adding any application then it runs ok but when i add the project to server and then strat it then error comes

"Tomcat 7 failed to start"

Initially the project was working properly but then i deleted few spring jars and then i added again but i get this error.

Now is there any way to find whats the problem. Any log files???

I'd recommend not starting it in Eclipse until you can start it outside of Eclipse successfully.

Open a command shell, make sure that the Tomcat /bin is in your PATH, and execute the catalina.bat script. You'll be able to see more detailed messages, if any, in the shell.

You should also check the Tomcat /logs directory to see what they can tell you.

The CLASSPATH ought to be set properly in the startup script.

UPDATE:

Since you know you can start Tomcat without Eclipse, you know that the issue is in the IDE.

My guess is that your project needs the Tomcat /lib JARs to be available and they're not. You can probably tell Eclipse to add all the JARs it finds in a particular directory to your CLASSPATH when you build and run (you can with IntelliJ). Right click on the project root and see if there's a drop down to add to the path.
