Tomcat won't display index.jsp

Hello, I've been working in a webapp the last couple of weeks, and I am new with tomcat and JSP technology, yesterday I try to display the index.jsp in http://localhost:8180 and it didn't display it .

I retart tomcat with

> sudo /etc/init.d/tomcat5.5 restart

and it give me an OK but it won't show up in my browser, I don't know how to fix it. I was editing index.jsp couple of days ago and I erase the content of the folder "work" in tomcat, but it worked ( display index.jsp ) , but I don't know if it is related, I haven't done much since then . So I am pretty much lost. Can someone help me please?
