new to custom tag. I have about 5 different JSP pages that need to have some common part. So I want to "take out" this common part (html with some customization, calculation, etc) and put in one tag library, so that all 5 pages can call it and use it. Is it required that each tag library can only be used by one JSP page ? or can be used by any number of JSPs ?

One of the major points of custom actions (tags) is reuse. So yes, they can be used across multiple pages.
 
Why is the word "abbreviation" so long? And this ad is so short?
