Starting Tomcat v6.0 Server at localhost fails

I am not able to start Tomcat v6.0 from Eclipse Helios.

I have my Java bin path set properly.

Moreover, I can start the server from outside of Eclipse manually. I could start it from Windows Services as well as using tomcat6.exe and see that it works correctly in my browser by typing localhost:8080 in the URL, but when I start from Eclipse a window appears saying that it encountered a problem while starting tomcat.

And my Console shows the following error:-

I also tried a solution here, but the problem still persists. However, the problem there is different from what I get.

How do I solve this?
