It inherits from the <CODE>Message</CODE> interface and adds a body containing a single reference to an object. Only <CODE>Serializable</CODE> Java objects can be used. <P>If a collection of Java objects must be sent, one of the <CODE>Collection</CODE> classes provided since JDK 1.2 can be used. <P>When a client receives an <CODE>ObjectMessage</CODE>, it is in read-only mode. If a client attempts to write to the message at this point, a <CODE>MessageNotWriteableException</CODE> is thrown. If <CODE>clearBody</CODE> is called, the message can now be both read from and written to.<P><P><DL><DT><B>Version:</B></DT> <DD>1.0 - 6 August 1998</DD><DT><B>Author:</B></DT> <DD>Mark Hapner, Rich Burridge</DD><DT><B>See Also:</B><DD><A HREF="../../javax/jms/Session.html#createObjectMessage()"><CODE>Session.createObjectMessage()</CODE></A>, <A HREF="../../javax/jms/Session.html#createObjectMessage(java.io.Serializable)"><CODE>Session.createObjectMessage(Serializable)</CODE></A>, <A HREF="../../javax/jms/BytesMessage.html" title="interface in javax.jms"><CODE>BytesMessage</CODE></A>, <A HREF="../../javax/jms/MapMessage.html" title="interface in javax.jms"><CODE>MapMessage</CODE></A>, <A HREF="../../javax/jms/Message.html" title="interface in javax.jms"><CODE>Message</CODE></A>, <A HREF="../../javax/jms/StreamMessage.html" title="interface in javax.jms"><CODE>StreamMessage</CODE></A>, <A HREF="../../javax/jms/TextMessage.html" title="interface in javax.jms"><CODE>TextMessage</CODE></A></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR></TABLE> <A NAME="fields_inherited_from_class_javax.jms.Message"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface javax.jms.<A HREF="../../javax/jms/Message.html" title="interface in javax.jms">Message</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../javax/jms/Message.html#DEFAULT_DELIVERY_MODE">DEFAULT_DELIVERY_MODE</A>, <A HREF="../../javax/jms/Message.html#DEFAULT_PRIORITY">DEFAULT_PRIORITY</A>, <A HREF="../../javax/jms/Message.html#DEFAULT_TIME_TO_LIVE">DEFAULT_TIME_TO_LIVE</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD>⌨️ 快捷键说明
