When you put JARs in $CATALINA_HOME/common/lib the Catalina internal classloader has access to these classes. This access is important for something like servlet.jar, but not generally required for applications.
The place to put shared things for application use is in a JAR under $CATALINA_HOME/lib or in unpacked classes under $CATALINA_HOME/classes. When you make a JAR globally available like this, you still need to include the individual TLD's in your web application. These are not made globally available, only the implementation classes.

Hello all, Although I'm using Tomcat v4.1.12 with Apache's JSTL Taglib, this issue really applies to *all* taglibs, not just JSTL: I'm finding that if I have several webapps (i.e., several Contexts), all using JSTL, I need to replicate the taglib JARs (jstl.jar and standard.jar) to the "WEB-INF/lib" directories of *each* webapp using JSTL. Of course, this means that each webapp loads its own copy of the classes contained in those JARs. That seems a bit wasteful. I would much rather put the JARs in a common directory, (e.g., Tomcat's "common/lib") thereby allowing all webapps to share the same JARs. Unfortunately, this technique does not work. When I move the JARs to Tomcat's "common/lib" directory I receive an error when I try to run a JSP containing a JSTL tag. The error message indicates the JAR (jstl.jar) cannot be found. My TLD resides in "\WEB-INF". I do *not* have <taglib> elements in web.xml. One suggestions I received was to include <taglib> elements in web.xml but that will not work since the <taglib-location> element cannot refer to a location outside the current context. Does anyone have an idea about this -- how to share taglib JARs across contexts?
