Error in Tomcat Server while reading JSP file

I have placed Commonsfileuploadservlet folder inside webapps. And inside that folder i have written upload.jsp

After switching on the tomcat server, while attempting to run the jsp file, the below error comes in the browser.

What might be the cause?

The requested resource (/Commonsfileu开发者_C百科ploadservlet/upload.jsp) is not available.

As requested by OP, I am reposting the comment which solved the problem as an answer:

Anything in server logs? Check for most recent log updates in Tomcat/logs folder. It might contain detail about startup errors.
