If I deploy the application (using myFaces) in JBoss 5 it works well. So the problem seems
to be related with the use of WLS 10.3 and myFaces 1.2.4.
> I tried with 1.2.3 and 1.2.2 and got the issue with both. I tried with 1.2.0 and got
another error:
> javax.faces.FacesException: weblogic.servlet.jsp.CompilationException: Failed to compile
JSP /index.jsp
> index.jsp:14:22: Static attribute must be a String literal, its illegal to specify an
expression.
