public class EmbeddedXADataSource40
extends org.apache.derby.jdbc.EmbeddedXADataSource

EmbeddedXADataSource40 is Derby's XADataSource implementation for JDBC4.0.

An XADataSource is a factory for XAConnection objects. It represents a RM in a DTP environment. An object that implements the XADataSource interface is typically registered with a JNDI service provider.

EmbeddedXADataSource40 supports the JDBC 4.0 specification for the J2SE 6.0 Java Virtual Machine environment. Use EmbeddedXADataSource if your application runs in the following environments:

• JDBC 3.0 - Java 2 - JDK 1.4, J2SE 5.0

EmbeddedXADataSource40 object only works on a local database. There is no client/server support. An EmbeddedXADataSource40 object must live in the same jvm as the database.

EmbeddedXADataSource40 is serializable and referenceable.

See EmbeddedDataSource40 for DataSource properties.

true if this implements the interface or directly or indirectly wraps an object that does.

Throws:

java.sql.SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

unwrap

public <T> T unwrap(java.lang.Class<T> interfaces)
         throws java.sql.SQLException

Returns this if this class implements the interface

Parameters:

interfaces - a Class defining an interface

Returns:

an object that implements the interface

Throws:

java.sql.SQLExption - if no object if found that implements the interface

java.sql.SQLException
