Listeners

Hi,

To not show password in the JDBC WsdlDataSourceTestStep, I create a TestRunListener, calling beforeRun(...) I am able to set the password, it only works when run a test case.
1. I want to do the same implementation when running the standalone test step, i.e. using a listener for a test step. How can I do it?
2. I want to do some actions when a project is saved but calling the Project listener method beforeSave => does not work

need to know how to configure the listener.xml for ProjectListener interface and some example of groovy script implementation
and also implementation of test step listener

thank you
