Upgrading to JSP 1.2 and Servlet 2.3 Specifications

See Also

The IDE supports the development of J2EE 1.3 applications, which mandate the use of the most recent versions of the JSP and Servlet specifications:

• The JavaServer Pages Specification, Version 1.2 available at http://java.sun.com/products/jsp
• The Java Servlet 2.3 Specification available at http://java.sun.com/products/servlet

You can load and execute web modules and web module groups that are compliant with earlier versions of these specifications. However, if you plan to continue developing the web modules, you must upgrade to the latest specification versions. Because certain actions require changes to the web.xml file for the web module, the IDE will prompt you to upgrade if you:

• Attempt to add Servlet 2.3 functionality, such as a Filter class, to the web module. Note that if you do not accept the upgrade, the servlet will still be created, but it will not be added to the deployment descriptor.
• Add a new servlet to the web module

If you choose to upgrade without being prompted:

1. On the Filesystems tab in the Explorer, right-click on node representing the web module or web module group to be upgraded.
2. Choose Tools Upgrade Web Application Version from the contextual menu.

You can also upgrade a 2.2 web application by setting the Web Application Version property value in the deployment descriptor (web.xml) to 2.3.
