An application may use the <code>setSocketFactory</code> method to request that the RMI runtime use its socket factory instance instead of the default implementation.<p> The default socket factory implementation used goes through a three-tiered approach to creating client sockets. First, a direct socket connection to the remote VM is attempted. If that fails (due to a firewall), the runtime uses HTTP with the explicit port number of the server. If the firewall does not allow this type of communication, then HTTP to a cgi-bin script on the server is used to POST the RMI call.<p><P><DL><DT><B>Since: </B><DD>JDK1.1</DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#RMISocketFactory()">RMISocketFactory</A></B>()</CODE><BR> Constructs an <code>RMISocketFactory</code>.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract java.net.ServerSocket</CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#createServerSocket(int)">createServerSocket</A></B>(int port)</CODE><BR> Create a server socket on the specified port (port 0 indicates an anonymous port).</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract java.net.Socket</CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#createSocket(java.lang.String, int)">createSocket</A></B>(java.lang.String host, int port)</CODE><BR> Creates a client socket connected to the specified host and port.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../../java/rmi/server/RMISocketFactory.html">RMISocketFactory</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#getDefaultSocketFactory()">getDefaultSocketFactory</A></B>()</CODE><BR> Returns a reference to the default socket factory used by this RMI implementation.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../../java/rmi/server/RMIFailureHandler.html">RMIFailureHandler</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#getFailureHandler()">getFailureHandler</A></B>()</CODE><BR> Returns the handler for socket creation failure set by the <code>setFailureHandler</code> method.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../../java/rmi/server/RMISocketFactory.html">RMISocketFactory</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#getSocketFactory()">getSocketFactory</A></B>()</CODE><BR> Returns the socket factory set by the <code>setSocketFactory</code> method.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#setFailureHandler(java.rmi.server.RMIFailureHandler)">setFailureHandler</A></B>(<A HREF="../../../java/rmi/server/RMIFailureHandler.html">RMIFailureHandler</A> fh)</CODE><BR> Sets the failure handler to be called by the RMI runtime if server socket creation fails.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/rmi/server/RMISocketFactory.html#setSocketFactory(java.rmi.server.RMISocketFactory)">setSocketFactory</A></B>(<A HREF="../../../java/rmi/server/RMISocketFactory.html">RMISocketFactory</A> fac)</CODE><BR> Set the global socket factory from which RMI gets sockets (if the remote object is not associated with a specific client and/or server socket factory).</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.lang.Object"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.lang.Object</B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE>clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait</CODE></TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><A NAME="constructor_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%">⌨️ 快捷键说明
