Chapter 17. Using JSP Tag Libraries
by Kunal Mittal
IN THIS CHAPTER
This chapter discusses how to use JSP tag libraries on the WebLogic server. The JSP tag library construct allows developers to port Java code away from JSP presentation pages by encapsulating Java code within tag implementation classes. Methods of these implementation classes are then called from JSP pages, using XML-like tag syntax. Within this chapter, JSP tag use, tag syntax, and the WebLogic custom tag library are discussed. Additionally, the WebLogic EJB to JSP Integration Tool, tag library resources, and best practices for implementing tag libraries are also addressed.
