The Tomcat installation directory is invalid. Missing the expected file or the file lib / jasper-el.jar


I have downloaded the Liferay Portal 6.1 Community Edition bundled with tomcat. Then i have downloaded the SDK for liferay. Following the steps given in this site to configure eclipse with liferay when i reach at the step 4 i got the following error.

All the related threads are specific to ubuntu. But i am using windows 7 64 bit. I am not getting how to solve this problem. All the files are present then why its showing me this error. Any help would be appreciated.

You appear to be trying to create a Liferay v6.0 Tomcat Runtime and then pointing the directory to a Liferay v6.1 Tomcat runtime (notice the 6.1.1 in the install path). So go back to the previous screen and choose Liferay v6.1 Tomcat Runtime instead. If you don't have v6.1 then you need to make sure you have the latest version of Liferay IDE installed (lastest version is 1.6.1).
