Cannot import external jar file in Rational Software Developer Platform

Hi, all:

I have struggled with this for a while -- this is semmingly such a simple and common task, which is really frustrating.

I have build a dynamic web project, I want to import an external jar file. I used Rational Software Developer Platform's utility to import the jar file, and I can see it right there in my project (under java resources). When I instantiate a class in this jar file, the context sensitive editor recognizes the class (it would auto-complete the statement, for example). So far so good. But, when I try to run the project, I got a javax.faces.el.EvaluationException: java.lang.NoClassDefFoundError.

It sounds like the compiler is able to recognize the jar file, but it is not in the runtime classpath. I've struggled for a few hours now and could not get it to work, any ideas?

Any help will be much appreciated.

You have to set the runtime dependencies ( for the jar that wants to use the other jar. You can do this by right clicking on the jar that contains the code to be executed.
So I left, I came home, and I ate some pie. And then I read this tiny ad:
