| javax.ejb.spi.HandleDelegate
| HandleDelegate | | public interface HandleDelegate (Code) | | The HandleDelegate interface is implemented by the EJB container.
It is used by portable implementations of javax.ejb.Handle and
javax.ejb.HomeHandle. It is not used by EJB components or by client components.
It provides methods to serialize and deserialize EJBObject and EJBHome
references to streams.
The HandleDelegate object is obtained by JNDI lookup at the reserved name
"java:comp/HandleDelegate".

| Method Summary | |
| public EJBHome | readEJBHome(java.io.ObjectInputStream istream)
Deserialize the EJBHome reference corresponding to a HomeHandle.
readEJBHome is called from the readObject method of portable HomeHandle
implementation classes. | | public EJBObject | readEJBObject(java.io.ObjectInputStream istream)
Deserialize the EJBObject reference corresponding to a Handle.
readEJBObject is called from the readObject method of portable
Handle implementation classes. | | public void | writeEJBHome(EJBHome ejbHome, java.io.ObjectOutputStream ostream)
Serialize the EJBHome reference corresponding to a HomeHandle.
This method is called from the writeObject method of portable HomeHandle
implementation classes. | | public void | writeEJBObject(EJBObject ejbObject, java.io.ObjectOutputStream ostream)
Serialize the EJBObject reference corresponding to a Handle.
This method is called from the writeObject method of portable
Handle implementation classes. |
| readEJBHome | | public EJBHome readEJBHome(java.io.ObjectInputStream istream) throws java.io.IOException, java.lang.ClassNotFoundException(Code) | | 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.
Parameters:
istream - - The input stream. The deserialized EJBHome reference.
exception:
java.io.IOException - - The EJBHome could not be deserialized becauseof a system-level failure.
exception:
java.lang.ClassNotFoundException - - The EJBHome could not be deserializedbecause some class could not be found. |
| readEJBObject | | public EJBObject readEJBObject(java.io.ObjectInputStream istream) throws java.io.IOException, java.lang.ClassNotFoundException(Code) | | 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.
Parameters:
istream - - The input stream. The deserialized EJBObject reference.
exception:
java.io.IOException - - The EJBObject could not be deserializedbecause of a system-level failure.
exception:
java.lang.ClassNotFoundException - - The EJBObject could not bedeserialized because someclass could not be found. |
| writeEJBHome | | public void writeEJBHome(EJBHome ejbHome, java.io.ObjectOutputStream ostream) throws java.io.IOException(Code) | | 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.
Parameters:
ejbHome - - The EJBHome reference to be serialized.
Parameters:
ostream - - The output stream.
exception:
java.io.IOException - - The EJBObject could not be serializedbecause of a system-level failure. |
| writeEJBObject | | public void writeEJBObject(EJBObject ejbObject, java.io.ObjectOutputStream ostream) throws java.io.IOException(Code) | | 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.
Parameters:
ejbObject - - The EJBObject reference to be serialized.
Parameters:
ostream - - The output stream.
exception:
java.io.IOException - - The EJBObject could not be serializedbecause of a system-level failure. |
