NoClassDefFoundError - please help

["Varma, Nitesh" <ni...@tvworks.com>]

I'm a newbie to Cactus and getting my feet wet.

Has anybody had problem with their Cactus test unable to instantiate the Servlet under test on the server side? I'll greatly appreciate any help /
hint. 

I came across NoClassDefFoundError issues on cactus-users mail archive, but my issue is different.

My cactified EAR file contains the Servlet WAR file and cactus.war file (which contains the Cactus test cases). The test's beginXXX() method executes
file, but when it enters the testXXX() method and tries to instantiate the Servlet to test, I get the following exception:

14:13:19,951 INFO  [STDOUT] java.lang.NoClassDefFoundError: com/liberate/vod/web/TVPV7FrontServlet
14:13:19,952 INFO  [STDOUT]at com.liberate.vod.web.test.MyServletTest.testGetRootFolder(MyServletTest.java:59)

14:13:19,952 INFO  [STDOUT] at java.lang.reflect.Method.invoke(Method.java:585)

I used the following to cactify my ear file:

<cactifyear srcfile="${cactify.dir}/${project.name}.ear" destfile="${cactify.dir}/${project.name}-cactified.ear">
  <cactuswar context="/cactus" version="2.3">
       <classes dir="${cactify.dir}/test/classes">
          <include name="**/*Test.class"/>
       </classes>
  </cactuswar>
</cactifyear>

This generates cactus.war with the following structure:

WEB-INF\classes\com\liberate\vod\web\test\MyServletTest.class
WEB-INF\lib +
            |-aspectrjt-1.2.1.jar
            |-cactus-1.7.1.jar
            |-commons-logging-1.0.4.jar
            |-junit-3.8.1.jar
WEB-INF\web.xml

Clearly, my ServletTestCase is not able to reference the Servlet under test, even though they are under the same EAR file (different WAR file though -
Servlet is in application WAR and test is in cactus war). So I don't know if there are classloader issues involved, and if so, then how to get rig=d
of them.

Thanks,

Nitesh
