Constructor Detail

JConnection

public JConnection(JManagedConnection xaConnection,
                   Connection physicalConnection)
Buils a Connection (viewed by the user) which rely on a Managed connection and a physical connection.

Parameters:
xaConnection - the XA connection.
physicalConnection - the connection to the database.
Method Detail

getConnection

public Connection getConnection()
Gets the physical connection to the database.

Returns:
physical connection to the database

isPhysicallyClosed

public boolean isPhysicallyClosed()
                           throws SQLException
Returns:
true if the connection to the database is closed or not.
Throws:
SQLException - if a database access error occurs

invoke

public Object invoke(Object proxy,
                     Method method,
                     Object[] args)
              throws Throwable
Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Specified by:
invoke in interface InvocationHandler
Parameters:
proxy - the proxy instance that the method was invoked on
method - the Method instance corresponding to the interface method invoked on the proxy instance.
args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments.
Returns:
the value to return from the method invocation on the proxy instance.
Throws:
Throwable - the exception to throw from the method invocation on the proxy instance. The exception's type must be assignable either to any of the exception types declared in the throws clause of the interface method or to the unchecked exception types java.lang.RuntimeException or java.lang.Error. If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the throws clause of the interface method, then an UndeclaredThrowableException containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.

handleObjectMethods

protected Object handleObjectMethods(Method method,
                                     Object[] args)
Manages all methods of java.lang.Object class.

Parameters:
method - the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.
args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance
Returns:
the value of the called method.

setCheckClose

public void setCheckClose(boolean cc)

isClosed

public boolean isClosed()
                 throws SQLException
Throws:
SQLException
