Description: The JRun Tag Library is a collection of custom actions based on the JavaServer Pages 1.1 (JSP) tag extension API. The custom actions (tags) provide JSP developers the convenience of developing Web applications that incorporate sophisticated client-side features and backend integration with technologies in J2EE (Java 2 Enterprise Edition). By using the JRun Tag Library, JSP developers can perform data queries/transactions, asynchronous message sending/receiving, email processing, and XML data processing (just to name a few) without knowing all the APIs involved.
