Using Web Service from LiveCycle PDF Dynamic Form.
I found out that I can use Acrobat Javascript object "identity" to get the Login Name "identity.loginName", but the main problem here is that more work is needed to deploy the form using this command, becuase:
1. The function must be called from a Priviliged context (Trusted Function), which is a Folder Level Script. This means I have to deploy the script for more than 1000 users. Also, if a user is smart, he will be able to hard-code the User ID inside the script, and we have a big problem here.
or
2. Make the PDF Certified, and ask every user to trust the certificate. Also this has to be done on every PC.
Both solutions above are not pratical.
Any suggestions how to automatically detect the User ID of the currently logged in user ?
Note: I am not convinced that I cannot use the "identity.loginName" directly inside the form using JavaScript ? As a matter of fact, putting this function in a folder level script is more risky, becusae the user can change it

Do you know how to pass credentials for the Web Service which is a DataConnection under LiveCycle ES Form (XFA) ?
Now, I am trying to pass credentials using SOAP.request call.
I have tried the following:
var cURL = "http://www.mssoapinterop.org/asmx/simple.asmx?wsdl";
var cTestString = "This is my test string";
// Call the echoString SOAP method -- it is an RPC Encoded method
var response = SOAP.request({
cURL: cURL,
oRequest: {"http://soapinterop.org/:echoString": {inputString: cTestString}},
cAction: "http://soapinterop.org/"
});
var result =
response["http://soapinterop.org/:echoStringResponse"]["return"];
// This should be the same as cTestString
console.println(result + " == " + cTestString);
and ... it is working ... now, I will move on to passing the Authentication Parameters.
Do you know a public web service that requires credentials for testing ? Becuase I am unable to test against local web services

I have developed a Web Service that will get the User ID of the currently logged in user. It is working fine.
Also, I can develop a Web Service Wrapper in ASP.NET to call the SAP Web Service. So, in the Web Service Wrapper, I will do all logic which requires Windows Based Authentication and other authorization logic, and finally call the SAP Web Service, and return the results back as usual.
I can see your idea about binding the full XML String to a hidden field, which I think it will work. But, I still do not know how to convert the result of the web service call to XML String. I am still working on that.
Could you please explain to me why it is a security concern to allow the client program to get the Windows Login ID ?
Don't you think that if you allow the user to write his own script (Folder Level Script) to get the Login ID, then it is of a higher risk ?
This reminds of the story of the mouse, the cat and the elephant

Thank you for your feedback.

Hello Tarek,
Thanks for the information! That should do the trick 
About the local web service: I sucessfully called a web service running on the same computer I used to fill the PDF form. So yes, calling "local" web services does work. I used a Tomcat server however, not IIS.
