    1.session.isNew() returns true ,i have used sesssion ,then why is it still a new session

    Probably because the server container has just created a new session. Take a look at the request and response headers and at your browser’s cookie cache. Is a session cookie being set? Does the session cookie keep changing?

    2.i am not able to use else in the jsp,getting syntax error on token

    Look at the Java code generated for the JSP and look for the syntax error there. The file will be some temporary directory in the web container directory tree.

    3.there is a log out button on the output.jsp
    now i want that on clicking the log out button,the user should able to go out of session

    You will need to do this in a servlet. The simple way would be to call invalidate on the Session object. This may or may not work, depending on how your login mechanism / session cookie management is implemented.
