【Abstract】 In order to solve the difficult problem that many existed software systems need to traverse several firewalls to obtain data through a special port, a kind of technique to traverse the firewalls by setting up HTTP tunnel using Java and XML is put forward after the working flow and working principles of the firewalls are analyzed. It is described how to adopt Servlet and Soaps to set up HTTP tunnel, how to change the data into the format of XML and how to transmit and exchange the data with the format of XML in Internet. The technical details to implement the technique are analyzed, and some suggestions on the further expansion and applications of the technique are put forward.更多还原
