You can access XA support for the Network Server by using the network client driver's XA DataSource interface.
You can use the org.apache.derby.jdbc.ClientXADataSource class on Java SE 5 and above (except Java SE 8 Compact Profiles), in applications that call JDBC 3 or JDBC 4.0 methods. You can use the org.apache.derby.jdbc.ClientXADataSource40 class on Java SE 6 and above (except Java SE 8 Compact Profiles), in applications that call JDBC 4.1 or JDBC 4.2 methods. You must use the org.apache.derby.jdbc.BasicClientXADataSource40 class on Java SE 8 Compact Profile 2 or 3.
If your client is running on the Java SE 6 platform or higher, all connection objects returned from the DataSource will be JDBC 4 connection objects, whether or not you are using a DataSource whose name ends in "40".
The following example illustrates how to obtain an XA connection with the network client driver:
import org.apache.derby.jdbc.ClientXADataSource;
import javax.sql.XAConnection;
...
XAConnection xaConnection = null;
Connection conn = null;
ClientXADataSource ds = new ClientXADataSource();
ds.setDatabaseName ("sample");
ds.setCreateDatabase("create");
ds.setServerName("localhost");
ds.setPortNumber(1527);
xaConnection = ds.getXAConnection("auser", "shhhh");
conn = xaConnection.getConnection();
