hi Chandra,
I store the url in one of hidden field in form, then copy javascript below to click event, button control type: Regular.
just replace all the "<>" in the code below.
var message;
var response;
// The name of the data connection will be pulled from the WSDLConnection name in the ConnectionSet packet
var sWSDLName = <DataConnection name>;
// clone, modify and execute the connection.
var vConnection = xfa.connectionSet[sWSDLName].clone(true);
vConnection.soapAddress.value = <url>;
// Execute the connection, without remerge data after the result.
var ws_rc = vConnection.execute(true);
for multiple data connection, you have to repeat these code with replace different data connection name and it's url address.
you may use script object (something like subroutine).
Regards,
