    Hi

    Im having a bit of trouble with some JSP pages I have tried to upload to a webserver. JSP is working perfectly on this server. Basically, Ill explain the structure of the site...

    The main website with its html pages and jps pages has the following makeup.

    public_html/images <-- images in there
    public_html/styles <--css in here
    public_html/jsp <-- all jsp files in here
    public_html/WEB-INF <-- all classes and libraries in here

    and then in public_html itself there are all the static HTML files for the site.

    This works absolutely fine. The problem lies here...
    I have created an admin folder in public_html for the site administrator so they can send out emails for a newsletter or manage users. Its basically a content management system based in JSP for them to use.

    public_html/admin/images <-- images in there
    public_html/admin/styles <--css in here
    public_html/admin/WEB-INF <-- all classes and libraries in here
    and in public_html/admin I have it all as jsp files instead of html files.

    the admin section is new so i thought it best to keep it all as jsp files since it will be dynamic.

    here is the error i get.

    org.apache.jasper.JasperException: /admin/newsletter_manager.jsp(5,0) The value for the useBean class attribute com.package.class is invalid.

    I have changed the class name to com.package.class for safety reasons. I know the info here might be alot but I thought I should include it incase it is needed. Does anyone have any idea why this is happening. I have looked on the net and there is little info on it and anything that has been suggested I have tried and it has not been the problem.

    Thanks

    Without much thought or understanding, I'd guess that it's something to do with your nested WEB-INF folder (/public_html/admin/WEB-INF) .. classes in there are more than likely not being picked up by Tomcat (or whatever your app server is). You could try moving out files in there back up to /public_html/WEB-INF.

    Hi

    Thanks for the reply. I have a WEB-INF folder deployed into public_html which has the same contents as the WEB-INF folder in public_html/admin.

    i use

    <jsp useBean id="object_name" class="com.package.classname" scope="page"/>

    and that comes up as the error in jsp. I called my web hosting company about this and they can't seem to do anything about it. Do I need to edit or create a web.xml file or set any classpaths in Tomcat. Im kind of new to Tomcat myself.

    Thanks

    Hi

    I got it fixed in the end. It turns out I was uploading an older version of the WEB-INF folder that didnt contain the classes I needed. Its amazing how these little things can hold up development for nearly half a day ! Thanks again for all your help.

    Regards
