To invite a user to a group chat room, address a new message to the user and set the room name appropriately, as in the following code example: <pre> Message message = new Message("user@chat.example.com"); message.setBody("Join me for a group chat!"); message.addExtension(new GroupChatInvitation("room@chat.example.com");); con.sendPacket(message); </pre> To listen for group chat invitations, use a PacketExtensionFilter for the <tt>x</tt> element name and <tt>jabber:x:conference</tt> namespace, as in the following code example: <pre> PacketFilter filter = new PacketExtensionFilter("x", "jabber:x:conference"); // Create a packet collector or packet listeners using the filter... </pre> <b>Note</b>: this protocol is outdated now that the Multi-User Chat (MUC) JEP is available (<a href="http://www.jabber.org/jeps/jep-0045.html">JEP-45</a>). However, most existing clients still use this older protocol. Once MUC support becomes more widespread, this API may be deprecated.<P><P><DL><DT><B>Author:</B></DT> <DD>Matt Tucker</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><A NAME="nested_class_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Nested Class Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static class</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.Provider.html" title="class in org.jivesoftware.smackx">GroupChatInvitation.Provider</A></B></CODE><BR> </TD></TR></TABLE> <!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.html#ELEMENT_NAME">ELEMENT_NAME</A></B></CODE><BR> Element name of the packet extension.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.html#NAMESPACE">NAMESPACE</A></B></CODE><BR> Namespace of the packet extension.</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.html#GroupChatInvitation(java.lang.String)">GroupChatInvitation</A></B>(<A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> roomAddress)</CODE><BR> Creates a new group chat invitation to the specified room address.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Method Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.html#getElementName()">getElementName</A></B>()</CODE><BR> Returns the root element name.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.html#getNamespace()">getNamespace</A></B>()</CODE><BR> Returns the root element XML namespace.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/jivesoftware/smackx/GroupChatInvitation.html#getRoomAddress()">getRoomAddress</A></B>()</CODE><BR>⌨️ 快捷键说明
