I guess I have to completely agree with this thread entitled Discussion: My favorite J2EE component is … DisplayTag on TSS. I have been using the display tag library since version 0.8 and have found it to be really useful and a huge time saver. Plus the ability to integrate with Struts is a nice plus.
If you've never seen or used it, the tag library display tables! Give it a list of objects and it will handle displaying of columns, sorting, paging, cropping, grouping, exporting, smart linking and decoration of the table in a nice and customizable xhtml style.
More information about the display tag library @ http://displaytag.sourceforge.net/ and http://www.displaytag.org/index.jsp
