I'm new to JSP, and I'm trying to reduce a massive amount of cut-and-pasted code. On each page in the project, there are around 25 lines of mixed JSP,Struts tags,JSTL tags, and HTML, which have been cut and pasted at various points in the page. These ~25 lines of re-used code are not even remotely similar from page to page (and there ~25...
I realise there are EL and near EL frameworks like StringTemplate, JUEL, Velocity, etc. However, I am not asking for list of alternatives to JSTL/EL.

Now I have to hunt around the taglib...
