[Salim Tol]

Hi! I got following parse error while starting tomcat 6.0. I am using myeclipse editor.

SEVERE: Parse Error at line 50 column 21: Attribute "scope" with value "page" must have a value from the list "request session ".

Please help me to solve this problem.
Thanks in advance.

I think there may be some issue with ActionServlet configuration in web.xml.
It would be easy to find out exact problem if you provide web.xml also.

That looks okay to me.

SEVERE: Parse Error at line 50 column 21: should give some idea to you about what customization have you done.

Try undeploy your webapp to be sure that it is not coming from some other deployed webapp.
