Hi folks, I need to represent lots of tabular data in a JSP web application. What are the best open source libraries to consider? I need sorting, paging and filtering facilities. Thanks

You might check displaytag (http://displaytag.sourceforge.net/1.2/) and yui (http://developer.yahoo.com/yui/). Both are well documented and easy to plug into your web pages. Displaytag is jsp-tag and yui a javascript library. Both treat sorting and paging. You can even rearrange the columns with yui. However filtering is not supported. But you can combine these two libs with jbfilter(http://code.google.com/p/jbfilter/). With jbfilter you can easyly build sophisticated filters and even choose to make the filtering on the database or in memory.
