Vincent
I have dome more investigation on this problem I have been getting.
I have written the following servlet and test case as attached.
(See attached file: TestViewStaffResourceServlet.java)(See attached file:
ViewStaffResourceServlet.java)
And when running them I still get the following errors.
>From tomcat
001-05-29 01:50:57 - Ctx( /staffResource ): Exception in: R( /staffResource +
/ServletRedirector + null) - java.lang.ClassCastException:

org.apache.commons.cactus.AbstractTestCase.runBare(AbstractTestCase.java:266)
This is the same error and same trace I was getting before as far as I know.
But there is progress .....
Within the Servlet method with the doSessionRequest method there are a set of
out.println() calls to build up some response HTML.
With these out.println() methods then the problem above occurs but if one
removes these print calls so there is no reponse HTML then the problem
disappears and tests work correctly, and test cases can be handled. Thus it
seems to me that there seems a conflict somewhere in the test suite code when
there is a session object and response data being BOTH sent back from a
PostMethod.
Other to you guys on this one, as I have not gone down the root of trying to
resolve where theere may be a problem in the Cactus code.
If it helps I am using the download of cactus common-cactus-23-20010502.
Please if someone can get to me with a resolution, I will be most greatful.
Cheers and thanks for any assistance to a real problem.

Hi Jon,
A few general remarks first :) (we'll tackle the hard problems just after
... )
* The beginXXX() methods are optional so if you don't use it, you can simply
remove it from the test, making it more readable
* If you're testing for a positive response, like a doPost that executes
correctly, you shouldn't try to catch a possible error in a try/catch block.
Just let the exception be bounced up in the call stack. It will eventually
be picked up by the JUnit test runner. Again, this is to make it easier to
read a test and guess it's intent.
Ok, now the hard part ...
It actually looks quite strange. The line that seems to cause problem seems
to be the following from ServletTestCaller.java (although I am not sure as I
may be using a newer version than yours)
" ServletTestResult result =
(ServletTestResult)theObjects.m_Config.getServletContext().getAttribute(TEST
_RESULTS);"
This line could return a null value if the attribute is not set but I don't
see how it could return an object of a type different than a
ServletTestResult unless :
* The getAtrtibute(TEST_RESULTS) calls returns a java object that is not a
ServletTestResult but as TEST_RESULTS is declared as 'private final static
String TEST_RESULTS = "ServletTestRedirector_TestResults";', I don't see how
this value could have been overwritten ...
No, sorry, I don't get it ... Could you try to trim your class under test
and your test class so that it contains minimum code (remove any unnecessary
code) that still triggers the error. Once done, could you send it to the
list ?
Thanks.
Vincent.
