Webservice with HTTP authentication

Question

Hi,
how do i supply the userid an password for a http authenticated webservice.  I already choose the option for http authentication on the security tab on the logical port.
Alos tried to find it in the Visual Admin to the server but i am stuck.
Greetings Danny.

Answer 1

There are two ways to do this
<b>Option 1: Hard code the Username/Password</b>
For this, use the method _setUser and _setPassword.
These are methods for your model class Request_<WebService>_PortType.... (the model class for the webservice). I invoked these methods in the wdDoInit method of the component controller class.
For example, i imported the WSDL for the RFC SXMB_GET_MESSAGE_LIST and used it like this:
Request_SXMB_GET_MESSAGE_LISTPortType_SXMB_GET_MESSAGE_LIST oRequest =
new Request_SXMB_GET_MESSAGE_LISTPortType_SXMB_GET_MESSAGE_LIST();
oRequest._setUser("bcuser");
oRequest._setPassword("password");
<b>Option 2: Use HTTP Destinations</b>
Open Visual Administrator and goto node Services, Destination Service. Create a HTTP destination with the URL of the webservice, maybe choose basic authentication and give the username / password. Now, you could use this HTTP destination in the component controller class. Even though there is a method _setHTTPDestinationName, this did not work for me. I had to write the following code to retrieve the URL, username, password from the HTTP destination
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import java.net.HttpURLConnection;
     InitialContext ctx ;
     Object obj;
     DestinationService dstService;
     Destination destination;
     HTTPDestination httpDestination ;
     HttpURLConnection httpurlconnection = null;
     Properties destprop = null;
     String url = "";
     String username = "";
     String password = "";
          ctx = new InitialContext();
          obj = ctx.lookup(DestinationService.JNDI_KEY);
          dstService = (DestinationService) obj;          
          destination = dstService.getDestination("HTTP","NC_IS");
          destprop = destination.getDestinationProperties();
          httpDestination = (HTTPDestination) destination;
          url = httpDestination.getUrl();
          username = destprop.getProperty("USERNAME");
          password = destprop.getProperty("PASSWORD");  
(I know the java code sucks and the purists will hang me; nevertheless it works)
Besides the code, you need to do the following as well:
(1) In the Package explorer, select your project, right click, cick on "Set Additional Libraries.."
(2) Select security.class and tc/sec/destinations/interface
(3) Click on menu Project > Properties, goto Webdynpro refereces node in the tree and add the following
    (a) Interface References: tcsecdestinations~interface
    (b) Service References: tcsecdestinations~service
All the best, try option 1 first before you embark on the second one.
