| 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 javax.ejb.EJBHome | readEJBHome(ObjectInputStream istream)
Deserialize the EJBHome reference corresponding to a HomeHandle.
readEJBHome is called from the readObject method of
portable HomeHandle implementation classes. | | public javax.ejb.EJBObject | readEJBObject(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, 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, 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 javax.ejb.EJBHome readEJBHome(ObjectInputStream istream) throws IOException, 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:
IOException - The EJBHome could not be deserializedbecause of a system-level failure.
exception:
ClassNotFoundException - The EJBHome could not be deserializedbecause some class could not be found. |
| readEJBObject | | public javax.ejb.EJBObject readEJBObject(ObjectInputStream istream) throws IOException, 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:
IOException - The EJBObject could not be deserializedbecause of a system-level failure.
exception:
ClassNotFoundException - The EJBObject could not be deserializedbecause some class could not be found. |
| writeEJBHome | | public void writeEJBHome(EJBHome ejbHome, ObjectOutputStream ostream) throws 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:
IOException - The EJBObject could not be serializedbecause of a system-level failure. |
| writeEJBObject | | public void writeEJBObject(EJBObject ejbObject, ObjectOutputStream ostream) throws 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:
IOException - The EJBObject could not be serializedbecause of a system-level failure. |
