Please give some idea to solve the issue using jod converter connection 
pooling. How this connection pooling working. We gone through 
DefaultOfficeManagerConfiguration.java and we changed parameters; even it 
doesnt take any action. Is there any way to change/configure. 

I am using jodconverter-core-3.0-beta-3 version in ubuntu10.04.

Thanks in advance....

Regards,
Venu
