It seems there is some problem in posting XMLs. Please find attached config in text format.

Hi Hardik,

Are you sure that web app is using exactly the same config as standalone app?

See http://stackoverflow.com/questions/17462289/java-net-unknownhostexception-occur-when-read-mybatis-xml-file

Is this machine connected to the internet?

I am connected to internet. I am using my company's network.

As per solution mentioned on above link states that we need to add below code in our DocumentBuilderFactory.

dbFactory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

How can we amend activiti code? I also tried with one approach here.

Download DTD manually and place them on classpath and amend DTD paths in every XML. But it doesn't seem feasible solution.

And strange thing here is that, if I run this program in standalone mode then it works fine. But when I run from web application, it fails. So there should not be network or firewall issue.

Please help me. My current project is stuck due to this.

No, you can't add that to activiti without effectively creating a custom version.

It must be a network issue, can't be anything else. Is this machine running behind a proxy?
I've got no clue about your network topology though … so it can be pretty much anything.

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