[J2eeunit-dev] ClassCastException from ant task

[Jason G. <jas...@lo...>]

Suggestions appreciated on this one - I'm pretty stumped.


This is my first attempt to use J2EEUnit, and I'm unable to kick off a
first test via ant.  I get the following exception:

------------------------
java.lang.ClassCastException: j2eeunit.ant.StopServerTask
	at j2eeunit.ant.RunServerTestsTask.callStop(RunServerTestsTask.java:89)
	at j2eeunit.ant.RunServerTestsTask.execute(RunServerTestsTask.java:62)
	at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:124)
	at org.apache.tools.ant.Target.execute(Target.java:153)
	at org.apache.tools.ant.Project.runTarget(Project.java:898)
	at org.apache.tools.ant.Project.executeTarget(Project.java:536)
	at org.apache.tools.ant.Project.executeTargets(Project.java:510)
	at org.apache.tools.ant.Main.runBuild(Main.java:421)
	at org.apache.tools.ant.Main.main(Main.java:149)
------------------------

This exception occurs at the line indicated with a '(2)' below (from
RunServerTestTask but with some of my own debugging).


------------------------
private void callStop()
    {
        if (m_StopTarget != null) {
            Task t=project.createTask("stopserver");
(1)         System.out.println("Stop task class name is:
"+t.getClass().getName());
            j2eeunit.ant.StopServerTask task;
(2)         task = (j2eeunit.ant.StopServerTask)t;
            ...
        }
    }
------------------------

Statement (1) prints out the expected 'j2eeunit.ant.StopServerTask', so I'm
a little mystified.  I suspected that this must be due to an inconsistent
ANT version (since StopServerTask derives from Task), but a recompilation
against my local ANT produces the same result.

I've noticed the following in the j2eeUnit release notes, and suspect that
it may be relevant to my problem:

"Moved to Ant 1.4alpha, 19th february 2001 (there were problems with
version 1.3beta2 regarding JUnit and the Execute task)."

Any thoughts - based on later release comments, it should work with ant
1.3?

Jason.


PS: I'm using 

ant: 1.3
ant-options: 1.3
servlet: 2.2
tomcat: 4.0
j2eeunit: 22-0.8.1
