    Default JSP class files

    Hi,

    I have transformed the web application pages and generated some .class files that are altered according to my needs and now I want my apps to run from these new .class files.
    How can I do this? Could anyone guide me?

    This question might seem naive but, I have altered the code of some functions inside the class files but the JSP files are still the old ones so how should it work?
    Is this correct that because the JSPs are finally turned into classes and when the app runs the class files are executed therefore the JSPs are not important?

    Could anyone clarify please?

    Hello.
    Let me point out the errors you have in your jsp.
    Firstly, you are missing import statement. By default, java.sql package is not imported. So you have to import it using "page" directive.
    Secondly, you don't have to externally declare HttpServletRequest and HttpServletResponse objects. They are available built-in in JSP.
    So directly use the JSP built-in objects to read the parameter and write the response. I think its "request" for HttpServletRequest. Just google it.
    Thirdly, you did not define some methods. One is getParam(). Where is it defined?
    Don't think of any classes now.
    Your JSP page will ultimately be reduced to a servlet and JSP engine will take care of it.

    Once again,
    -- import the necessary packages
    -- use JSP built-in objects to read the URL parameters. It is "request".
    -- provide the definition of the methods you have defined such as getParam().

    Let me know if the problems still persist.

    Syed.

    Hi and thanks for your reply.
    I should say that you are totally right those parts are missing but they are all included in the common page. There is no problem with the JSp codes they work fine because they have been generated with CodeCharge and have been tested for many years.
    I have altered some parts of the java code and saved the altered pages as .class files.
    At the moment I need to get sure that the way I test the altered apps is correct (copying the new altered .class files inside the dir .../org/apache/jsp/) I need to run the apps from the new altered .class files not the old ones that do not have the altered parts.

    Regards
