Strutstestcase problem - exception thrown by action not being caught

Question

Hi,
I am experiencing a problem in a test class I wrote to test part of a Struts based application. I have posted this problem on the StrutsTestCase forum but not had a response yet (it doesn't seem to be frequently visited/posted at) so thought I would try my luck here.
The action performs some back-end processing and if all successful then returns a mapping forward. If an error occurs then an Exception is thrown. The config file contains the entry for the ExceptionHandler which displays the error message on the page (i.e. it calls the same jsp page that the action was first submitted from).
This all works fine when tested through the browser. Running a successful test via CactusStrutsTestCase also works correctly. But when I try to run a test to validate the error path the test class errors and the cactus output file indicates the Exception was thrown. BUT in my test class method...
public void testFileUpload()
this.setRequestPathInfo("/mypath");
this.addRequestParameter("action", "uploadFile");
MyForm form = new MyForm();
form.setFormFile(this.getUploadFile("empty.txt"));
this.setActionForm(form);
try
this.actionPerform();
System.out.println("got here OK -----------------------");
catch (Exception e)
System.out.println("got here ERROR -----------------------" + e.getMessage());
I try to catch the Exception so I can determine whether the test passed/failed but it is never caught. Instead the test just errors and neither debug line above is printed on the console. Yet the output file indicates that at the 'this.actionPerform();' line an error was uncaught...
<testcase classname="test.MyCactusTest" name="testFileUpload" time="4.87">
<error message="An uncaught exception was thrown during actionExecute()" type="org.apache.cactus.internal.client.ServletExceptionWrapper">servletunit.struts.ExceptionDuringTestError: An uncaught exception was thrown during actionExecute()
     at servletunit.struts.CactusStrutsTestCase.actionPerform()V(CactusStrutsTestCase.java:546)
     at test.MyCactusTest.testFileUpload()V(MyCactusTest.java:34)
I'm bemused! Any help is much appreciated.
