Adding an attribute to an ANT task

Hi,
I want to add a new attribute lets say category into the Junit task, which has other attributes like fork,haltonerror etc., I want to add this attribute and provide implementation to it, any idea which all source codes I should dig, I am using junit4.0, junit-ext-0.2.4.
1.)Is there a code or configuration in ANT which has list of all attributes of a task.
2.)For providing implementation to the new attribute in the junit task, do I need to modify the JunitTask, JunitRunner and classes of ant-junit.
Any good idea will be highly appreciated.

Thanks

Each attribute of an ant task is stored in a field of the class that implements that ant task. So what you would want to do is find the class that implements the junit ant task, extend it, and add a field for your attribute. Then what you do with that attribute value is up to you.

Here's the source to a test task I wrote a while ago. It has a single attribute "arg1" for which a setter method needs to be provided. It also shows how to retrieve a property from the build file, and various calls to the project environment. You'd use it with <MyTask arg1="foobar"/>.

Hi
On similar lines this prog is tried
The details are as under viz., buildfile,java prg and the succesful out put
Since you were able to get the attribute added ,please give the sample code to enable me for a try on this
similarly
