JSP and Servlets
JSP (JavaServer Pages) are Java programs encoded within webpages that research and generate pertinent results. Servlets, on the other hand, are objects (programs) that handle requests from users and provide results based on these requests.

This essentially means that there was an error with the code of the page and that the server could not accomplish, or fulfill it's request. You'll have to try again later.
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.
MVC refers to Model View Controller architecture.
Jsp pages are the view part of the MVC architecture...
Yes, JSP can output XML. To do this, simply output XML instead of HTML inside the JSP. A good idea is to start the JSP with a <%@page contentType="application/xml; charset=UTF-8" %> header, so that the correct contentType gets set.
What is the difference between sort and asort in PHP?
sort() will order the array by its values without preserving the keys. Use it when array is indexed numerically or when you do not care about the keys.
asort() will also sort the array by its values, but it will preserve the key -> value association.

Which one is faster servlet OR jsp?
Servlet is more faster than JSP, but JSP is more convenient than Servlet and JSP is clearly superior, shorter, simple and easier to use. JSP can be perceived as Java in HTML code. JSP require no explicit compilation as like servlets and can keep in the web application server as HTML file. The web application server in turn compile the java code in JSP and load it in its library for future execution. Servlet can be perceived as HTML in Java code. The servlet is the class file, which would be loaded in the web application server as a program. The program output will be directed to the outstream object which in turn direct to the client as HTML elements.
