NoClassDefFoundError Trying to Test Filter
All,
I'm trying to use cactus 1.2 to test a filter in the Oracle OC4J app
server, which is actually Orion (1.5.x, I believe). I've followed the
getting started guide correctly, in terms of setting up the server side
classpath, but I've been unable to get this test to work.
Here's my setup:
- I'm deploying a web application archive (WAR) in an EAR file.
- The WAR file has the following layout:
WEB-INF
|- web.xml [contains entries for the cactus redirectors]
|- classes [My classes under test and test classes
|- lib
|- cactus.jar
|- junit.jar
|- log4j-core.jar
When I run the junit test from my ANT build file, the test report that
is generated contains the following error:
<testcase name="testDoFilter" time="1.202">
<error message="org/apache/cactus/FilterTestCase"
type="org.apache.cactus.client.ServletExceptionWrapper">java.lang.NoClassDefFoundError:

The cactus server log file contains the following entries: [Formatting

I would be most grateful if anyone could shed any light on this
problem. It appears to be a problem with my classpath, but I can't
figure out how to fix it.
Thanks in advance,

Ok. Hum ... don't know ...
Are you 100% sure there is no cactus.jar in your system classpath or in
your EAR (specified in META-INF/manifest.mf using Class-Path) ?
Can't think of anything else right now, sorry.
Question: Have you tried using the Cactus sample (as is) with Orion
1.5.x (there is a sample script for Orion 1.5.x) ?
Thanks

Re: NoClassDefFoundError Trying to Test Filter
Posted by "Taylor,Timothy L." <tt...@mitre.org>.
I am using the servlet 2.3 version of the cactus jar. The stack trace I
included in my first post actually showed that the FilterRedirector is
executed.
C:\projects\Metrics\src\lib>jar tvf cactus.jar | grep Filter
749 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/client/FilterHttpClient.class
909 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/FilterTestCase.class
2287 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/server/FilterConfigWrapper.class
990 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/server/FilterImplicitObjects.class
3696 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/server/FilterTestCaller.class
779 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/server/FilterTestController.class
3393 Wed Feb 27 17:37:10 EST 2002
org/apache/cactus/server/FilterTestRedirector.class
What's got me so confused is that it can find the
FilterTestRedirector.class class file, but it can't find the superclass
of my test class (FilterTestCase).
At first, I thought that it might be caused by the fact that the
AbstractTestCaller class is calling Class.forName() to load the test
classes since this will not work if the class calling forName was loaded
by a ClassLoader higher in the loader chain than the one that can load
the class passed as the argument to forName(). But both cactus.jar and
my test classes are served by the same classloader, so I don't think
this is the problem.
I also tried changing the AbstractTestCaller to use the 3 arg version of
Class.forName() and passing the Thread Context ClassLoader as the third
arg. This didn't help either, in fact I verified that the ClassLoader
of the AbstractTestCaller is the same as the thread Context ClassLoader.

hum ... The only reason I can see at this point has to do with the
Cactus jar you're using. Are you sure you're using the Cactus for
Servlet API 2.3 and not the one for Servlet 2.2 (which does not contain
the FilterTestCase) ?
