I’ve read emails [1<\/a>] [2<\/a>] from a couple different people on the various email lists that CFMX can’t use sockets…. which is true in the sense that CFMX doesn’t have a <cfsocket> tag, but not true in the sense that you can’t easily use sockets in ColdFusion. I banged around this morning for a bit and came up with this example, which does an HTTP request of www.mindseye.com using a java.net.Socket<\/a> object and then loops over the returned headers and prints them out to the screen:<\/p>\n

<cfscript>
\n\/\/ get a socket object
\nsocket = CreateObject(“java”, “java.net.Socket”);<\/p>\n

\/\/ call the Socket constructor
\nsocket.init(“www.mindseye.com”, 80);<\/p>\n

\/\/ get a PrintWriter object
\nprintWriter = CreateObject(“java”, “java.io.PrintWriter”);<\/p>\n

\/\/ call the PrintWriter constructor
\nprintWriter.init(socket.getOutputStream(), true);<\/p>\n

\/\/ get an InputStreamReader object
\ninputsr = CreateObject(“java”, “java.io.InputStreamReader”);<\/p>\n

\/\/ call the InputStreamReader constructor
\ninputsr.init(socket.getInputStream());<\/p>\n

\/\/ get a BufferedReader object
\ninput = CreateObject(“java”, “java.io.BufferedReader”);<\/p>\n

\/\/ call the BufferedReader constructor
\ninput.init(inputsr);<\/p>\n

\/\/ request the homepage
\nprintWriter.println(‘GET \/index.cfm’);
\n      
\n\/\/ loop over result by reading line by line
\nrun = true;
\nwhile (run) {
\n   \/\/ read the result line by line
\n   resultLine = input.readLine();
\n   if (len(resultLine) GT 0) {
\n      WriteOutput(“Header: ” & resultLine & “<br \/>”);
\n   } else {
\n      run = false;
\n   }
\n}   
\n<\/cfscript><\/p>\n

You could easily modify this to write xml to a server socket:<\/p>\n

printWriter.println(‘<order orderType=”quote” customerType=”RETAIL” orderNumber=”1234″ orderDate=”2003-03-21″>’);
\nprintWriter.println(‘<shipment ID=”1″ city=”Boston” state=”MA” zip=”02210″>’);
\nprintWriter.println(‘<line_item ID=”1″ SKU=”18JK23″ category=”GSHOE” quantity=”2″ total=”39.90″ \/>’);
\nprintWriter.println(‘<\/shipment>’);
\nprintWriter.println(‘<\/order>’);<\/p>\n
