Getting Class Not found Exception when try to run test in eclipse

Question

I am Creating Test Automation Script for web application. I want to write test caes for JSP file. For JSP i am using JwebUnit library. i created test file as follows:

class Junittest {

@Before
public void prepare() {
         setTestingEngineKey(TestingEngineRegistry.TESTING_ENGINE_HTMLUNIT);        
         setBaseUrl("http://localhost:8081/JSPServer/jsp/");        
      }     
@Test       
public void test() {
            beginAt("home.jsp");        
            assertTitleEquals("Echoing HTML Request Parameters");
         }
}

when i try to run JUnit test it is giving me exception as follows :

java.lang.NoClassDefFoundError: org/apache/regexp/RESyntaxException
at net.sourceforge.jwebunit.junit.JWebUnit.getTester(JWebUnit.java:62)

I put home.jsp file in JSPServer -> webcontent -> jsp.

when i try to run file on server it is working correctly. When i try to run the JUnit test it is giving above exception.so can anyone suggest me solution for this ?

Answer 1

It is missing a library in its build path (best guess Jakarta Regexp jar). Add the jar to your build path. Might just solve your problem.
