| 35 | * This is Derby's network XADataSource for use with JDBC3.0 and JDBC2.0. |
| 36 | * </p> |
| 37 | * An XADataSource is a factory for XAConnection objects. It represents a |
| 38 | * RM in a DTP environment. An object that implements the XADataSource |
| 39 | * interface is typically registered with a JNDI service provider. |
| 40 | * <P> |
| 41 | * ClientXADataSource automatically supports the correct JDBC specification version |
| 42 | * for the Java Virtual Machine's environment. |
| 43 | * <UL> |
| 44 | * <LI> JDBC 3.0 - Java 2 - JDK 1.4, J2SE 5.0 |

| 46 | * </UL> |
