Migrate web application components
- Migrate web application components from WebSphere Application Server Version 5.x
Migration of web applications deployed in previous versions of WAS is usually not necessary. Versions 2.2 and later of the Java Servlet specification and versions 1.2 and 1.4 of the JSPs (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 WebSphere Application Server V8.0 and later, the default JavaServer Faces (JSF) implementation has changed to MyFaces.
- Migration scenario for the getHeaderNames method
WebSphere Application Server Version 8 and later supports the Java Servlet 3.0 API.
