Connecting to server machine w/ Activiti from a local machine

[themahc]

We are senior students in the University of Alabama's MIS program. 
We are currently working on a feasibility assessment of Activiti's features for enterprise integration for a company that we are contracted.

Our problem is that we are unable to connect to Activiti from a local machine to the server that has Activiti on it.

We have the server's IP address and are attempting to establish a jdbc connection via the information provided in the Activiti user guide.

On the server machine:
    We have successfully installed Apache Tomcat 7.0, Activiti, and PostgreSQL.
    We have Activiti connected to PostgreSQL as a standalone database and not in-memory, therefore, our data is preserved even when we close Activiti.
    We have the demo settings set to

false‍

and changed db.properties to

db=postgres
jdbc.driver=org.postgresql.Driver
jdbc.url=jdbcostgresql://localhost:5432/activiti
jdbc.username=
jdbc.password=

We have the same setup on the local machine as the server machine.
We have used square brackets around the server's IP address.

Is this the same problem as your other post (where it was resolved?)
