Maven classpath question

Hi,

I'm using an older version of Maven (1.1), but hopefully this question is
still relevant.  I have a test module that includes this dependency in its
project.xml file ...

    <dependency>
      <groupId>com.caucho</groupId>
      <artifactId>resin</artifactId>
      <version>3.0.9</version>
    </dependency>

However, when I run my JUnit test, I get the ClassNotFoundException below. 
The reason it is strange is because that class exists within the dependency
above.  Can you think of some ways I can troubleshoot this problem further?  

Thanks, - Dave

Download the jar and verify this file is inside the Jar before doing
anything else.

I've seen similar things posted on this list more than once, and
several times it turned out the Jar simply did not contain the class
file(s) they thought it did...
