I'm starting here as it's a jsp related topic. How do I get jstl working using netbeans. I'm using the head first jsp book and it says I have to copy the jstl files into the /web-inf/lib directory. however, when I create my web project, there is no such dir. Under the Libraries tree, I added them through the library manager, but I when I run the app, I get this exception that basically says I don't know where the jstl.jar files are...do I need to put them in the web.xml file?
