    Default Confused about setting up JSP

    As far as I can figure out, I have set up my server connection correct, because when I go to http://localhost:8080/ it takes me to the Tomcat test page that says I have set up my server connection correctly. However, when I change the location of the index.jsp page from the standard \webapps\ROOT to a folder that I created, \webapps\ROOT\jpages, the page will not display when I go to http://localhost:8080/jpages/index.jsp.

    I'm not sure that I have everything set up correctly, even though I followed the installation and set-up instructions exactly.

    I have other question about how to get JSP to work with a JavaBean, but I have to first resolve these issues before I ask them. I have an hunch that some of my problem will be resolved once I figure out how to access index.jsp wherever I put it, but I can't be sure until I can do that.

    Its been a while since I've used Tomcat, but the directory doesn't sound correct. You should double check to make sure this directory is the correct location to place your servlets/jsp files (which I'd guess is the webapps folder, not in the ROOT folder

    I figured out part of the problem: I did have the right directory, but the text editor I was using (Notepad) was not saving my JSP files with the .jsp extension, but with a .jsp.txt extension.

    I can change the extension manually from the command line, but that is, to say the least, slightly inconvenient. Is there a way to get Notepad to stop appending the .txt extension to the files I save with the .jsp extension?

    I think you should look into using a proper IDE like Eclipse or Netbeans for this kind of stuff. That would also give you the power of inline validation.

    When it comes to adding a Java bean/class to the request/session so you can use it in your JSP file all you need to do is this.

    final MyJavaBean myJavaBean = new MyJavaBean();
    request.setAttribute("nameOfTheBean", myJavaBean);

    Now in your JSP all you need to do is get the bean off the request.

    final MyJavaBean myJavaBean = (MyJavaBean) request.getAttribute("nameOfTheBean");

    Now this is not really best practise and instead you should use something like JSTL for this.

    Have a look at JSTL 1.0: What JSP Applications Need, Part 2 - O'Reilly Media
