BOS 5.10.1 to Openedge Progress

I'm trying to connect a BOS 5.10.1 installation on a Windows 2008 R2 server via JDBC.

Other Windows processes use ODBC to complete this task, and so I've been given those settings to c configure the JDBC. I've also had the DB Admin confirm the case settings as correct, just in case it was case sensitive.

My settings are

Server : lwsv03dev02 Port : 30050 Database : pinsys User : “report” Password : “report” Query: “select * from repcode”

so using the "JDBC -- Execute a query on any DB using JDBC"

Driver - org.postgresql.Driver URL - jdbc:postgresql://lwsv03dev02:30050/pinsys User name : report Password : report Query : select * from repcode

getting bp_DCS_1 error, org.postgresql.util.PSQLException: Protocol error. Session setup fail

I'll keep looking for self help, but if anybody has any pointers on how to fix it would be appreciated.

Regards

Lawrence
