Here are the steps to perform this reduction.
Copy all the necessary TLD of the COTS jar files into a location in your workspace say WEB-INF\tld Change the web.xml to have the references to the TLD files
By default you can remove these jar files from the WEB-INF\LIB folder. Ensure that you have deployed these JAR files as LIBRARY into the application server Generate the EAR file and you should see happy smiles on the deployer. http://java.sun.com/jsp/jstl/core /WEB-INF/tld/c.tld
