I have a Java application that uses JDBC (via JPA) that was connecting to a development database using hostname, port and Oracle SID, like this:

```none
jdbc:oracle:thin:@oracle.hostserver1.mydomain.ca:1521:XYZ

```

XYZ was the Oracle SID. Now I need to connect to a different Oracle database that does not use a SID, but uses an Oracle "Service Name" instead.

I tried this but it doesn't work:

```none
jdbc:oracle:thin:@oracle.hostserver2.mydomain.ca:1522:ABCD

```

ABCD is the Service Name of the other database.

What am I doing wrong?
