Headless Exception

Hi All ,
I have a process working with a server 8.2 which runs without a GUI.
I am doing porting to 8.3 , on CentOS 5.0 ,
The server compiled fine, and installed + running.
USING JDBC:postgresql-8.3-604.jdbc4.jar and tried
postgresql-8.3-604.jdbc3.jar too.
When i start my process , i am getting the following Exception:
java.awt.HeadlessException

The process is compiled and running with Java 1.6 , and i tried
assigning -Djava.awt.headless=true and false , and it doesn't help -
naturally since that jscan needs X.
Is there a way to bypass the X need? and use the driver with no X ?
The process is working fine with postgresql-8.2-506.jdbc3.jar - but i
am guessing it will show starnge errors in time (since the server is
8.3).

Any help would be appreciated.
