There is an IDE called WSAD - Websphere Studio Application Developer. It has inbuilt tools to debug everything (servlets & jsps inclusive)
I have heard from my friends that Eclipse too has some plugins that can help us debug jsps. The MyEclipse plugin for Eclipse also has tools for debugging Servlets and JSPs. Debugging a JSP in MyEclipse is a little tricky sometimes, depending upon the Java Application Server you are using. In theory, it should not be too difficult to debug a JSP as when it is compiled, it is compiled into a Servlet anyway.

jsp means Java Server Pages.
You cannot. You display JSP Pages using the help of Servlets. Servlets are of the background classes and you cannot display them
The Difference between JSTL and JSP is that, JSP lets the person add embedded Java code into HTML pages. Also JSP allows the person to define their own tags. JSTL is just a standard tag library provided by Sun to carry out common tasks.
JSP stands for Java Server Pages. It is the face of any web application. I.e., the stuff you see on a web page can be JSP contents. The JSP uses the features of both Java and HTML to display dynamic contents on a web page. It interacts with Servlets in a MVC architecture to provide the power to display dynamic and advanced data on any given web page.
JSP actions are XML tags that direct the server to use existing components or control the behavior of the JSP engine. JSP Actions consist of a typical (XML-based) prefix of "jsp" followed by a colon, followed by the action name followed by one or more attribute parameters. There are six JSP Actions: < jsp : include / > < jsp : forward / > < jsp : plugin / > < jsp : usebean / > < jsp : setProperty / > < jsp : getProperty / >
