                              The following script shows how you can call the FOP server from a Visual Basic 6 program:

                              Dim inet
                              Dim xml As String
                              Dim Chunk() As Byte
                              Dim Size As Long
                              Dim Remaining As Long

                              'Create instance of object
                              Set inet = CreateObject("InetCtls.Inet")
                              'Set timeout to say 20 secs
                              inet.RequestTimeout = 20

                              'input XML data
                              xml = "<?xml version=""1.0"" encoding=""iso-8859-1""?> <departments><department><departmentName>R&amp;D</departmentName> <person> <name>John Schmidt</name> "
                              xml = xml & "<address>Red street 3</address> <status>A</status> </person> <person> <name>Paul Bones</name> <address>White street 5</address> <status>A</status> "
                              xml = xml & "</person> <person> <name>Mark Mayer</name> <address>Blue street 5</address> <status>A</status> </person> <person> <name>Janet Black</name> "

                              xml = xml & " <status>A</status> </person></department></departments>"

                              'Call the FOP Server, passing the name of the template in the URL
                              inet.Execute "http://localhost:8087/J4LFOPServer/servlet?TEMPLATE=departmentEmployees.fo", "post", xml, "Content-Type: text/xml"
