Because jConnect requires no information about the kind of socket it is, you must complete any configuration before you return a socket.

For additional information, see:

• EncryptASE.java – located in the sample2 subdirectory of your jConnect installation, this sample shows you how to use the SybSocketFactory interface with jConnect applications.

• MySSLSocketFactoryASE.java – also located in the sample2 subdirectory of your jConnect installation, this is a sample implementation of the SybSocketFactory interface that you can plug in to your application and use.
