Method Detail

writeEJBObject

public void writeEJBObject(EJBObject ejb,
                           ObjectOutputStream out)
                    throws IOException

Serialize the EJBObject reference corresponding to a Handle. This method is called from the writeObject method of portable Handle implementation classes. The ostream object is the same object that was passed in to the Handle class's writeObject.

Specified by:

writeEJBObject in interface HandleDelegate

Parameters:

ejb - The EJBObject reference to be serialized.

out - The output stream.

Throws:

IOException - The EJBObject could not be serialized because of a system-level failure.

readEJBObject

public EJBObject readEJBObject(ObjectInputStream in)
                        throws IOException,
                               ClassNotFoundException

Deserialize the EJBObject reference corresponding to a Handle. readEJBObject is called from the readObject method of portable Handle implementation classes. The istream object is the same object that was passed in to the Handle class's readObject. When readEJBObject is called, istream must point to the location in the stream at which the EJBObject reference can be read. The container must ensure that the EJBObject reference is capable of performing invocations immediately after deserialization.

Specified by:

readEJBObject in interface HandleDelegate

Parameters:

in - The input stream.

Returns:

The deserialized EJBObject reference.

Throws:

IOException - The EJBObject could not be deserialized because of a system-level failure.

ClassNotFoundException - The EJBObject could not be deserialized because some class could not be found.

writeEJBHome

public void writeEJBHome(EJBHome home,
                         ObjectOutputStream out)
                  throws IOException

Serialize the EJBHome reference corresponding to a HomeHandle. This method is called from the writeObject method of portable HomeHandle implementation classes. The ostream object is the same object that was passed in to the Handle class's writeObject.

Specified by:

writeEJBHome in interface HandleDelegate

Parameters:

home - The EJBHome reference to be serialized.

out - The output stream.

Throws:

IOException - The EJBObject could not be deserialized because of a system-level failure.

readEJBHome

public EJBHome readEJBHome(ObjectInputStream in)
                    throws IOException,
                           ClassNotFoundException

Deserialize the EJBHome reference corresponding to a HomeHandle. readEJBHome is called from the readObject method of portable HomeHandle implementation classes. The istream object is the same object that was passed in to the HomeHandle class's readObject. When readEJBHome is called, istream must point to the location in the stream at which the EJBHome reference can be read. The container must ensure that the EJBHome reference is capable of performing invocations immediately after deserialization.

Specified by:

readEJBHome in interface HandleDelegate

Parameters:

in - The input stream.

Returns:

The deserialized EJBHome reference.

Throws:

IOException - The EJBHome could not be deserialized because of a system-level failure.

ClassNotFoundException - The EJBHome could not be deserialized because some class could not be found.
