dbConnection = DriverManager.getConnection(connectionURLString, connectProperties);

Connection URL: jdbc:postgresql://127.0.0.1:5432/key_tables

What is "jdbc:postgresql:MR"? Is this a valid URL string?

Above works fine with eclipse, jdk 1.7_45, 9.3-1101.jdbc41.jar

Test of your URL:

Connection Parameters: jdbc:postgresql:key_tables?user=danap&password=&loglevel=0
ClassNotFoundExceptionjava.lang.ClassNotFoundException: org.postgresql.Driver
SQLExeceptionjava.sql.SQLException: No suitable driver found for
jdbc:postgresql:key_tables?user=danap&password=&loglevel=0

Which would result in NULL being returned as you have indicated.

danap.
