Stream rules in your applications that use JSP tags can include references to tags in an external tag library (taglib):
1. Copy the tag library JAR file to the /lib directory:
<webserverbase>\webapps\prweb\WEB-INF\lib
2. Update the Dynamic System Settings data instance to add the new library to the class paths.
3. Stop and restart the application to make the Dynamic System Settings effective.
4. Update stream rules as desired to reference the new tags.
JSP tag support is based on Jasper 2.0 from the Apache Software Foundation.
The pegatags.jar file implements the Pega Platform tags.
