Problem with Cactus and Ant
Hi guys,
my name is Petar Tahchiev and I am one of the developers of Jakarta Cactus.
I have a really strange problem, when using Ant > 1.6.5.
When trying to execute my cactus tasks, I invoke actually the JunitTask, I
get the
following exception:
-----------------------------------------------------------------------------

Total time: 8 seconds
------------------------------------------------------------------------------------------------
However, if I downgrade to Ant 1.6.5 I don't get this exception and
everything passes
smoothly. Looking at the source code of the task, on line 1272 here is what
we see:
runner = delegate.newJUnitTestRunner(test, test.getHaltonerror(),
test.getFiltertrace(),
test.getHaltonfailure(), false,
true, classLoader);
so it turns out that delegate is null !!!
In Ant 1.6.5. there seems that this "delegate" object is missing. Also when
we look on line 799
we see that delegate is explicitly nullified:
------------------------------------------------
delegate = null;
------------------------------------------------
????
Does these thoughts make any sense, and if yes, how can I resolve my
problems.
Thank you.

Re: Problem with Cactus and Ant
Posted by Peter Reilly <pe...@gmail.com>.
It may be easier to copy all of junittask and modify it rather
than extending it.
JUnitTask is complicated and tricky - it needs to handle
classloading to allow junit.jar to be placed in a nested <classpath>
Details on the implementation will change from ant release to ant
release - the task
(and most others!) should have been made final when first written..

Re: Problem with Cactus and Ant
Posted by Petar Tahchiev <pa...@gmail.com>.
So actually you have to look here:
http://svn.apache.org/repos/asf/jakarta/cactus/trunk/integration/ant/src/java/org/apache/cactus/integration/ant/CactusTask.java
and this is the peace of code that actually executes the test:
===========================================
private void executeInContainer(ContainerWrapper theWrapper,
DeployableFile theFile)
{
log("Starting up container", Project.MSG_VERBOSE);
ContainerRunner runner = new ContainerRunner(theWrapper);
runner.setLogger(new AntLogger(getProject()));
try
{
URL url = new URL(theWrapper.getBaseURL() + "/"
+ theFile.getTestContext()
+ theFile.getServletRedirectorMapping()
+ "?Cactus_Service=RUN_TEST");
runner.setURL(url);
runner.startUpContainer();
log("Server name retrieved from 'Server' HTTP header: ["
+ runner.getServerName() + "]", Project.MSG_VERBOSE);
try
{
Enumeration tests = getIndividualTests();
while (tests.hasMoreElements())
{
JUnitTest test = (JUnitTest) tests.nextElement();
if (test.shouldRun(getProject())
&& !theWrapper.isExcluded(test.getName()))
{
if (theWrapper.getToDir() != null)
{
test.setTodir(theWrapper.getToDir());
}
execute(test);
}
}
}
finally
{
log("Shutting down container", Project.MSG_VERBOSE);
runner.shutDownContainer();
log("Container shut down", Project.MSG_VERBOSE);
}
}
===========================================
and the test-case in "execute(test)" is NOT null - I explicitly checked it.
In my opinion the only reason for the NLP is because the delegate
object is null :-(.
Any suggestions?

or test is null.

Its an addition that lets Ant load junit if it is on the classpath of
the tests; there's no longer any need to have it on ant's own classpath.
We don't plan to roll back to the old design, so the problem with Cactus
becomes one of determining hw

but if you look at execute(), you see
delegate = createMirror(this, mirrorLoader);
How does cactus override execute()? Does it call super.execute(), or
does it do something else? If you point us at the SVN copy of the task,
we can look for ourselves and see. It may be that you are calling some
internal execution stuff before a delegate is set up
