I have a .tag file that requires a javascript library (as in a .js file). Currently I am just remembering to import the .js file in every JSP that uses the tag but this is a bit cumbersome and prone to error. Is there a way to do the importing of the .js inside the JSP tag? (for caching reasons I would want the .js to be a script impo...

Hello This is a problem that only occurs on application update (only tested through Admin Console, not CLI).

Hi, I seem to remember reading that it's possible to declare taglib directives such as: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> in web.xml. This eliminates the need to duplicate this directive in every JSP file where the taglib is used. Could someone tell me how these directives can be added to web.xml? Chee...

For example: out.write("<div class=\"bar\">"); ... out.write("</div>"); i...

I have a similar problem, here I have a jsp tag that generates some HTML and has a generic js-implementation that handles the behavior of this HTML. Furthermore I need to write some initialization statements, so I can use it afterwards through J...

I am implementing a tree tag for one of my practice projects, where I would display the contents of a directory in the form of a tree (recursively). I had implemented a similar requirement as a Custom Tag in Java during the pre-JSP2.0 days. Handling a directory needs recursion (to handle the subdirectories)! Is it possible to code this a...
