System-independent (and transportable) web service

Question

Hello,
I would like to use a web service in my Interactive Form. Therefore, I created an RFC function module and created the corresponding web service. Then I launched SOAMANAGER to get the URL of the WSDL file, copy it, changed it a bit (removed the last part: "?sap-client=100", otherwise Adobe LiveCycle Designer would not accept it) and pasted into the "New Data Connection" dialog box in ALCD.
But this URL is system-dependent (begin with the development system hostname). So, once transported to other systems (integration, quality or production), it won't work anymore.
So, my first question is: how to make it system-independent?
My second question is: how to transport web services?
Thanks in advance.

Hi,
Sorry for the late reply. It was tricky, but I finally found out how to make it system independant. It was really tricky to make it work fine, so here is the solution:
1) The Web Service URL will have to be an entry parameter of the Interactive PDF. You can generate it this way:
  CONSTANTS: lc_http_protocol_id  TYPE icmproto VALUE 1,
             lc_web_service_name  TYPE string   VALUE 'my_web_service_name',
             lc_http              TYPE string   VALUE 'http://',
             lc_web_service_dir   TYPE string   VALUE 'sap/bc/srt/rfc/sap',
             lc_sep               TYPE c        VALUE '/'.
    CALL FUNCTION 'ICM_GET_INFO'
      TABLES
        servlist = lt_server_info.
    LOOP AT lt_server_info  INTO ls_server_info
                            WHERE active = abap_true
                            AND protocol = lc_http_protocol_id.
*                            AND hostname CS sy-host.
    ENDLOOP.
    IF sy-subrc EQ 0.
      CONCATENATE lc_http ls_server_info-hostname ':' ls_server_info-service INTO lv_web_service_url.
      CONCATENATE lv_web_service_url
                  lc_web_service_dir
                  lc_web_service_name
                  sy-mandt
                  lc_web_service_name
                  lc_web_service_name
                  INTO lv_web_service_url
                  SEPARATED BY lc_sep.
2) In the Interactive Form, use the following javascript code:
try {
     var urlObject = xfa.record.WEB_SERVICE_URL;
     var url = urlObject.value;
     var request = {};
     request["urn:sap-com:document:sap:soap:functions:mc-style:MyWebServiceMethod"] = {myParameter: 'My parameter value'};     
     var response = SOAP.request({
          cURL: url,
          oRequest: request,
          cNamespace: "urn:sap-com:document:sap:soap:functions:mc-style"
// get the response values
     xfa.record.MyValue.value = response["urn:sap-com:document:sap:soap:functions:mc-style:MyWebServiceMethod"]["MyResponseParameter"];
} catch (e) {
     xfa.host.messageBox(e.toString());
