Error while building ibatis SqlSessionFactory: Error creating document instance. Cause: java.net.UnknownHostException:

[hardik_thakkar1]

Hello,

I am currently facing issue with calling activiti from web application. I am getting below exception. I explored activiti forums for this issue. I could not find any concrete resolution. I am already connected to internet so network issue can not be main cause of this issue.

Any help on this would be much appreciated.

PS - If I run this program standalone then it is working fine. But when I run it in web application, it fails.

The original author never replied with follow up. I suspect it's a corporate firewall intervening.
