문제

i am trying to run JSF2/PrimeFaces application on WebSphere 6.1 and my configuration is as follows:

  • Class loader order: Classes loaded with application class loader first.
  • WAR class loader policy: Class loader for each WAR file in application.

My Jars are as follows:

From the JSF 2.1 specification:

Other Java™ Platform Specifications

JSF is based on the following Java API specifications:

  • JavaServer Pages™ Specification, version 2.1 (JSP™)
  • Java™ Servlet Specification, version 2.5 (Servlet)
  • Java™2 Platform, Standard Edition, version 5.0
  • Java™2 Platform, Enterprise Edition, version 5.0
  • JavaBeans™ Specification, version 1.0.1
  • JavaServer Pages™ Standard Tag Library, version 1.2 (JSTL)

Therefore, a JSF container must support all of the above specifications.

WebSphere Application Server 6.1 is a J2EE 1.4 implementation and only supports Servlet 2.4.

You should ideally move to WAS 8 as Java EE 6 platforms support JSF 2 by specification.
