OpenDeploy Adapter for getting filelist

System

I am using OD 5.6 and I want to get filelist on the OD server. I thought of using OD Adapters. The out-of-the box adapter AdapterExample works perfectly fine.
I changed the class name to say 'Adapter1', compiled and built odadapter.jar and put it in <iwhome>/userlib. finally modified the config file(test.xml) to add the lines
<odAdapterSet>
<odAdapter name="Adapter1" parameter="" />
</odAdapterSet>
It doesn't work.
the server log file says
<odAdapterSet><odAdapter name="Adapter1" parameter="null"/></odAdapterSet>

-----------------------------
But if i change the fileback to AdapterExample.java and repeat the whole process it works.
I think there is one more configuration I am missing.
