At work I currently write a lot of custom JSP-Tags for our designers, which are written in JSP's XML flavour (rather than Java classes).
When I typo'ed or made a mistake and try to load the TLDs or tag files, Tomcat always just throws the non-descript error: Could not add one or more tag libraries.
Now I have to hunt around the taglibs finding out which one is borked and do trial and error - noone's preferred way of debugging.
Eclipse is unfortunately useless at validating taglibs.
Are there any tools around that could help me? The icing on the cake would be Maven integration. I have tried this plugin, but no luck.
