- Migrating web application components from WAS v5.x
Migration of web applications deployed in previous versions of WebSphere Application Server is usually not necessary. Versions 2.2 and later of the Java Servlet specification and versions 1.2 and 1.4 of the JSP specifications are still supported unless the behavior was changed in the Servlet 3.0 or JSP 2.1 specifications. These changes are generally available in more detail in their corresponding specification.- JavaServer Faces migration
In WAS V8.0 and later, the default JavaServer Faces (JSF) implementation has changed to MyFaces.- Migration scenario for the getHeaderNames method
WAS v8 and later supports the Java Servlet 3.0 API.- JSP migration
