Java-based JDBC connection Oracle 11g RELEASE2 Case Analysis

The example in this article describes Java's approach to Oracle 11g RELEASE2 based on JDBC. Share to everyone for your reference. Specifically as follows:

The JDBC connection for Oracle 11g Release 2 appears to be different if you receive the following exception:

Listener refused the connection with the following error:ora-12505, Tns:listener does no currently know of SID given in C Onnect Descriptor.

Then you must use the following connection method:
