Programming WebLogic JSP


Overview of Java Server Pages (JSP)

This document is an introduction and reference for the basic syntax of JavaServer Pages (JSP). It provides information about how to use JSP with WebLogic Server. It is not intended as a comprehensive guide to programming with JSP.

The following sections provide an overview of JSP:


What Is JSP?





WebLogic Implementation of JSP

BEA WebLogic JSP supports the JSP 1.2 specification from Sun Microsystems. JSP 1.2 includes support for defining custom JSP tag extensions. (See Programming JSP Extensions)

The WebLogic Server implementation of the JSP 1.3 specification calls getOutputStream rather that getWriter to output characters in a JSP. This can cause certain extended characters to be truncated and to appear incorrectly. Using HTML code for extended characters such as the Angsrtom unit and the degree symbol will ensure that they will be processed correctly by your WebLogic Server instance.

WebLogic Server also supports the Servlet 2.3 specification from Sun Microsystems.


How JSP Requests Are Handled

WebLogic Server handles JSP requests in the following sequence:

  2. WebLogic Server reads the request.

It is also possible to invoke the JSP compiler directly without making a request from a browser. For details, see Using the WebLogic JSP Compiler. Because the JSP compiler creates a Java servlet as its first step, you can look at the Java files it produces, or even register the generated JspPage servlet class as an HTTP servlet.
