Hi Steve,
Thanks a lot for your reply.

What does it mean ?
I try to apend the code below:
project.log( echoval,"XXX", Packages.org.apache.tools.ant.Project.
MSG_WARN);
But this doesn't work,,,
I try to do MSG_DEBUG, MSG_ERR, MSG_INFO, MSG_VERBOSE ...
The output of console did display the same result..
Best Regards,
