Hello, I am trying to run a backend application (using spring and hibernate 3.0) from another application written in (Struts/Hibernate 3.0 deployed on JBOSS).
Both JBOSS and the backend application reside on the same Linux box.
When i run the backend application by itself through linux bash script it runs fine but when i call from struts using java.lang.Runtime it hangs...
I found this in the log of the backend application...
I am posting this here because i am suspecting a possible conflict between hibernate thats with the backend application and the hibernate with the struts application.

please note this is just a partial log... there were 10 -15 other table mappings that were successfully mapped by the HbmBinder not sure why it would wait infinitely for this particular table mapping.

another thing i would like to point out is that...
when i run in backend it does this successfully

Any pointers will be greately appreciated... thanks

This turned out to be a java's "Runtime.exec()" issue

Lesson learned is:
You must immediately handle the input, output, and error streams from your spawned external process.
