Apache Tomcat 8 not working. Throws HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.index_jsp

IT'S WORKING!

What I did:

1. Opened command prompt using "Run as administrator"

2. Went to the "bin" directory of Tomcat folder.

   cd C:\Program Files\apache-tomcat-8.0.3\bin'  
   

3. Entered 'startup' to run 'startup.bat' and the server started
4. Opened a web browser entered http://localhost:8080/ and it worked like charm. This also started generating Tomcat log files too.

The only different thing I performed is "Run as administrator".

But I checked with Tomcat7 it did not require me to "Run as administrator" but it worked; not sure why
