7.4 JSP Tag Libraries

When using tag libraries within a WAR or WAB, be sure to include an Import-Bundle or Import-Library for the tag library bundle(s). This will ensure that your WAR or WAB can see the TLD definition and implementing types. For example, to use the Apache implementation of JSTL, add the following to your bundle’s /META-INF/MANIFEST.MF:

Import-Bundle: com.springsource.org.apache.taglibs.standard;version="1.1.2"

Import-Package can also be used but it is tedious to add all the imports as there are typically lots of tld definitions in a bundle providing them.
