36  * This is Derby's network XADataSource for use with JDBC3.0 and JDBC2.0.

38  * An XADataSource is a factory for XAConnection objects. It represents a
39  * RM in a DTP environment. An object that implements the XADataSource
40  * interface is typically registered with a JNDI service provider.
41  * <P>
42  * ClientXADataSource automatically supports the correct JDBC specification version
43  * for the Java Virtual Machine's environment.
