JDBC working as extension but not servlet

[rob_mac]

I have no problems using JDBC when called from PHP using the java extension.

However I am lead to believe this is very inefficient as each page on my site would be spawning JVM's. So I have decided to use the servlet method under orion.

But when I run the PHP as a servlet I am getting a socket connection error from the jDBC connect:

java.sql.SQLException: [Microsoft][SQLServer JDBC Driver]Error
establishing socket.

Anybody know what the differences are that could cause this error, the configurations for the db and logins are the same....
