Custom Task and classloader problem ?

[Vincent Massol]

Hi,

I have 2 custom tasks defined in my own jar file (package name :
j2eeunit.ant). I try to call one of my task from the other task.

Here is my task definition in my build.xml

        <taskdef name="startserver"
classname="j2eeunit.ant.StartServerTask">
            <classpath>
                <pathelement location="lib/j2eeunit-22-0.8.jar"/>
                <pathelement path="${java.class.path}"/>
            </classpath>
        </taskdef>

        <taskdef name="runservertests"
classname="j2eeunit.ant.RunServerTestsTask">
            <classpath>
                <pathelement location="lib/j2eeunit-22-0.8.jar"/>
                <pathelement path="${java.class.path}"/>
            </classpath>
        </taskdef>

Here is the portion of code that I use to call the other task :

        StartServerTask task;

        Object o = project.createTask("startserver");
        System.out.println("class = " + o.getClass().getName());

        task = (StartServerTask)o;

It fails with a class cast exception .... !

Now, if I bundle my tasks in ant.jar and I removed the taskdefs, everything
works fine. It seems it is a classloader problem ...
Is there a way to solve this ? It seems that the Taskdef task uses the
AntClassLoader class to load tasks. Is that the problem ? How can I remedy
it ?

Thanks.
