Dear all, To Ali and Ken: I attached "xmltest.php" and java files "postXMLClient.zip" that I used for debugging. It demonstrates how to send a message from NYU to Gatech. A Java file sends me a XML file over http and the php file receives the XML file and print it out. I used JRE 1.6 and developed in Eclipse. Just changing a variable "serverURL" with "http://localhost/appropriate_directory_name/xmltest.php" is needed. To Mrunal: Here are a processing code, php codes, and java files that I used for my debugging. You can use this processing code or write your own code. For testing you need to use "PostXMLClient.zip". In postXML.java you need to change serverURL with "http://localhost/appropriate_directory_name/postXML.php" Regards, Myungcheol --- Myungcheol Doo http://www.cc.gatech.edu/~mcdoo M.S. student in Computer Science, Georgia Tech
