4.2.2.3.7: IBM extensions to JSP syntax

Refer to the Sun JSP Specification for the base JavaServer Pages (JSP) APIs. IBM WebSphere Application Server Version 3.5 provided several extensions to the base APIs. The backward compatibility of the JSP 1.1 specification to JSP 1.0 allows users to invoke these APIs without modification.

The extensions belong to these categories:

Extension Use
Syntax for variable data Put variable fields in JSP files and have servlets and JavaBeans dynamically replace the variables with values from a database when the JSP output is returned to the browser
Syntax for database access Add a database connection to a Web page and then use that connection to query or update the database. The user ID and password for the database connection can be provided by the user at request time, or can be hardcoded within the JSP file.

Scope of variables: Because the values specified by syntax apply only to the JSP file in which the syntax is embedded, identifiers and other tag data can be accessed only within the page.

See the Related information for syntax details.
