title: how to use one jar that depends on another jar
body: <p>suppose in my application "MyClass", I want to use class A in jar1, and some part of class A depends on some class B in jar2. If I put both jar1 and jar2 on my classpath and run MyClass, it still complains that class B can not be found.</p>
  
  <p>Could anybody tell me how to fix this problem?</p>
  
  <p>Thanks a lot.</p>
