Hi, Just a few ideas:
1) MyFaces 1.2 requires java 1.5 or later, JSP 2.1, JSTL 1.2 and a Java Servlet 2.5 implementation [1] and I'm not sure, if Tomcat 5.0.28 provides that. 2) JSF 1.2 uses the unified expression language, which also includes javax.el.ValueExpression, so maybe you have to provide the implementation for this manually (commons-el.jar) or there's a class loading problem that causes the null value. Another thing: You could try to run it with facelets. Maybe this will work and help you solve your JSP problem. Also using Facelets would not be that bad, because JSF 2.0 supports them out-of-the-box anyway.
