Description

According to the requirement specifrication, MyFaces 1.1 is supposed to support java 1.3 or later, JSP 1.2, JSTL 1.0, and a Java Servlet 2.3 implementation. Unfortunately, the FacesConfigurator is using the javax.servlet.jsp.el package, which is only available since JSP 2.0.

Following classes to use wrongly javax.servlet.jsp.el.

• org.apache.myfaces.shared_impl.util.ClassUtils
• org.apache.myfaces.shared_impl.util._Coercions
• org.apache.myfaces.config.ManagedBeanBuilder
• org.apache.myfaces.el.ELParserHelper
• org.apache.myfaces.el.MethodBindingImpl
• org.apache.myfaces.el.ValueBindingImpl

Issue is related to the fact, that the apache commons-el 1.0 package is used, which requires the JSP 2.0 interfaces. This issue can be solved by reworking in two ways

1) Rework the interfaces for commons-el to remove the dependency for JSP 2.0

2) or by Adding the missing classes manually. You need to remove the annotations within the source code and compile it using Java 1.3

• ELException
• Expression
• ExpressionEvalutator
• FunctionMapper
• VariableResolver

The corresponding exception thrown within my j2ee container below
