I am trying to run a test from XSDGeneratorTest.java. But I get the following exception:

I tried to claen and build the project many a times but still same error! I tried all the options from JUNIT Test class in Eclipse - java.lang.ClassNotFoundException, but none worked for me!

Answer 1

If that happens when you moved your project from one IDE/OS to another, just try to remove the JUnit3 library and add it again. Sometimes that fails when you bring your proyect from outside. I was stuck getting the same error until I did that.
