Migrate web application components
- Migrate web application components from WAS v5.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 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, the default JavaServer Faces (JSF) implementation has changed to MyFaces.
- Migration scenario for the getHeaderNames method
WAS v8 supports the Java Servlet 3.0 API.
- JSP migration
