Since you're using a JSP 1.2 container (Tomcat 4), this is all you have to do (assuming the JAR files contains the TLD file, and that the TLD contains a default URI declaration, but that's usually the case for Jakarta libraries). When you start the container, it looks through all files under WEB-INF to locate all tag libraries. As long as you use the default URI for the library in your taglib directive, it's able to figure out which library you refer to. For instance, if you have installed the Jakarta Standard library (the JSTL reference implementation), a taglib directive like this makes the JSTL core library available within the page: <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %> > The tld files into my webapps/ROOT/WEB-INF catalog. No need to install the TLD files; they are already part of the JAR files and web container will find them there. > Then I am suppost to change my web.xml file I guess. [...] No, that's not necessary when you use a JSP 1.2 container, see above. > Since I don't have done anything else (changed classpath or anything) I > guess I might have to do that to? No need to change the classpath. You have placed the JAR files in the WEB-INF/lib directory, which is already part of the containers classpath. > How do I test the taglibs so it works? Anyone have a small piece of code so > I can figure out when it is working... All Jakarta tag libraries come with a test application. If you install it you can just copy some tests from the test application to your application (the ROOT application in your case). Alternatively, just read the library documentation and try something out.
