Duke's Bank compile Error

I'm trying to get Duke's Bank (the tutorial) to compile to build my first J2EE application. I am getting the following error...
compile-web:
[javac] Compiling 4 source files to C:\inc\bank\build
[javac] C:\inc\bank\src\com\sun\ebank\web\template\DefinitionTag.java:59: inconvertible types
[javac] found : javax.servlet.jsp.JspContext
[javac] required: javax.servlet.jsp.PageContext
[javac] PageContext context = (PageContext)getJspContext();
[javac] ^
[javac] C:\inc\bank\src\com\sun\ebank\web\template\InsertTag.java:58: inconvertible types
[javac] found : javax.servlet.jsp.JspContext
[javac] required: javax.servlet.jsp.PageContext
[javac] javax.servlet.jsp.PageContext context = (PageContext)getJspContext();
[javac] ^
[javac] 2 errors
I haven't modified the files in question, they are straight from the tutorial. Everywhere I have checked the syntax appears to be correct. Any suggestions?

A little context might help out here. Since JspContext is new with JSP 2.0, I am assuming that you are compiling against a Servlet 2.4 library and using a JSP 2.0 container?

Good question, I will check it out. I am using JBoss with Tomcat, and I also have a separate install of struts with Tomcat. I'll have to check the differences in the versions and what I am using in my classpath. The safe thing to do might be to try the Duke's Bank example with version 1.3 instead of 1.4? I have so many things going on with Jboss, Struts, Tomcat, etc... that I am getting a little confused on what is talking to what.

Okay, I believe you have helped me a lot. I still need to test, but I downloaded the Duke's Bank sample with Java 1.4. Hence the use of the JspContext classes. I am using Tomcat 4.1.29 which only supports Serlvet/JSP Spec - 2.3/1.2. It sounds like I have two options...
1) Use Duke's Bank Sample with Java 1.3
2) Upgrade Tomcat to 5.0.18
Thoughts?

Well, the Java version you are using is much less important than the versions of the Servlet and JSP spec that the container supports.
But if the samples were written using APIs from Java 1.4, Servlet 2.4 and JSP 2.0, you really have no choice but to upgrade to these versions if you want to get the samples working.
