    50      *    InputStream.

    51      * <p>2. Invoke method implementation.

    53      *    ResponseHandler.

    54      * <p>4. If user exception occurred, create exception reply using

    55      *    ResponseHandler.

    56      * <p>5. Marshal reply into OutputStream returned by

    57      *    ResponseHandler.

    58      * <p>6. Return OutputStream to ORB.

    59      * <p>

    60      * @param method The method name.

    61      * @param input The <code>InputStream</code> containing the marshalled arguments.

    62      * @param handler The <code>ResponseHandler</code> which the servant uses

    63      * to construct a proper reply

    64      * @return The <code>OutputStream</code> created by the

    66      * @throws SystemException is thrown when invocation fails due to a CORBA system exception.
