Which technology for what purpose: JSP, Servlet, JSF, Struts, Web Services

[Rebecca Witmer]

I know how to write a servlet and how to write a JSP but I keep hearing people talk about these other technologies. I read about them somewhat on the wikipedia but I don't have a very good idea how the terms relate to each other. JSPs and Servlets are pretty basic units. I gather that these other technologies are more like ways of using them. Even more different, web services seem like they are a concept, not really a specific technology.

Somebody help me out with the big picture here. How do these technologies relate to each other? How are they the same or different? What is one good example of an application that would lend itself well to being written in each? Is there anything else I should've included in the list to get a full understanding?

Anything anyone wants to throw out there will be very helpful.
Thanks.

JSF and Struts are merely frameworks that use JSP and Servlet technologies. You never need to use them unless you determine that they have some value for you.

Visit the Web Services forum for more details on how it fits into the picture.
