SSL Socket connection via proxy

[fla5h]

I am trying to connect to a secure web page (https) and read the contents, all sounds simple right?&nbsp;&nbsp;I have to go through a proxy.&nbsp;&nbsp;I am using JSSE 1.01 and basicaly running one of the samples that comes with JSSE.&nbsp;&nbsp;This is the code...<br><br>// set up ssl socket to do tunneling through proxy<br>tunnelHost = System.getProperty(&quot;https.proxyHost&quot;<br>tunnelPort = Integer.getInteger(&quot;https.proxyPort&quot.intValue();<br><br>Socket tunnel = new Socket(tunnelHost, tunnelPort);<br>doTunnelHandshake(tunnel, host, port);<br>SSLSocketFactory factory = (SSLSocketFactory)SSLSocketFactory.getDefault();<br>SSLSocket socket = (SSLSocket)factory.createSocket(tunnel, host, port, true);<br><br>// register a callback for handshaking completion event<br>socket.addHandshakeCompletedListener(new HandshakeCompletedListener() {<br>public void handshakeCompleted(HandshakeCompletedEvent event) {<br>&nbsp;&nbsp;&nbsp;&nbsp;System.out.println(&quot;Handshake finished!&quot;<br>&nbsp;&nbsp;&nbsp;&nbsp;System.out.println(&quot;\t CipherSuite:&quot; + event.getCipherSuite());<br>&nbsp;&nbsp;&nbsp;&nbsp;System.out.println(&quot;\t SessionId &quot; + event.getSession());<br>&nbsp;&nbsp;&nbsp;&nbsp;System.out.println(&quot;\t PeerHost &quot; + event.getSession().getPeerHost());<br>}<br>});<br><br>// send http request<br>PrintWriter out = new PrintWriter(<br>new BufferedWriter(<br>&nbsp;&nbsp;new OutputStreamWriter(<br>&nbsp;&nbsp;socket.getOutputStream())));<br><br>out.println(&quot;GET <A HREF="

HTTP/1.1&quot;<br>out.println();<br>out.flush();<br><br>// read response<br>BufferedReader in = new BufferedReader(<br>&nbsp;&nbsp;&nbsp;new InputStreamReader(<br>&nbsp;&nbsp;&nbsp;socket.getInputStream()));<br><br>String inputLine;<br><br>while ((inputLine = in.readLine()) != null)<br>System.out.println(inputLine);<br><br>in.close();<br><br>----------------------------------------------<br>If I run the code Im told that the line:<br>&nbsp;&nbsp;&nbsp;&nbsp;out.flush();<br>Causes exception:<br>java.lang.IllegalArgumentException<br> void java.io.PrintWriter.flush()<br> void SSLSocketClientWithTunneling.doIt(java.lang.String, int)<br> void SSLSocketClientWithTunneling.main(java.lang.String[])<br><br>But, if I run the code in debug mode and add a break point on the out.flush() line and use debug to step over it the code works fine?<br><br>Any help would be well received.<br><br>fl@5h

ummm... put it in a try/catch block with nothing in the catch block? what happens then? <p>Liam Morley<br><a href=mailto:lmorley@wpi.edu>lmorley@wpi.edu</a><br><a href=

I should have said, it is in a try catch block.&nbsp;&nbsp;Thats how it catches the<br><br>java.lang.IllegalArgumentException:&nbsp;&nbsp;out.flush();<br>void java.io.PrintWriter.flush()<br>void SSLSocketClientWithTunneling.doIt(java.lang.String, int)<br>void SSLSocketClientWithTunneling.main(java.lang.String[])<br><br>I am thinking the problem might be a timing issue with the proxy?&nbsp;&nbsp;The JSSE code fires off a few threads which is making impossible for me to try and trace for debugging.
