WCF Service, Java JApplet client, transport error 405

Question

Hi all, I'm having a problem with a WCF Service and Java Client, I will try to give as much information as i can, thanks for your time.

The Endpoint of the server is BasicHttpBinding, I tried hosting the server as a Windows Service and in IIS but nothing changed. The weird thing is that the Client works great if I use a simple class, in the moment I switch the class to an JApplet I get the problem mentioned.

I'm using Eclipse as an IDE, I tried Axis and Metro to generate the stub with the same bad results.

Here is an example of the Java class where everything is working

public class TestSoaMetro {
    public String TestMethod(){
     String result=null;

      IDigitalSignatureService aa = new DigitalSignatureService().getBasicHttpBindingEndpoint();
      try {
       result= aa.getData("1", "id002962");
      } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
      } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
      }
     return result;
    }
}

Here is the example of the JApplet where I get the error:

public class TestSoaMetroApplet extends JApplet {
     public void init() {
         Container content = getContentPane();
         content.setBackground(Color.white);
         content.setLayout(new FlowLayout()); 
         String result= this.TestMethod();
         JLabel label = new JLabel(result);
         content.add(label);
       }
    public String TestMethod(){
     String result=null;
     IDigitalSignatureService aa = null;
     try {
      aa = new DigitalSignatureService().getBasicHttpBindingEndpoint();
      result= aa.getData("1", "id002962");
     } catch (IDigitalSignatureServiceGetDataArgumentExceptionFaultFaultMessage e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     } catch (IDigitalSignatureServiceGetDataInvalidOperationExceptionFaultFaultMessage e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
    return result;
    }
}

In the moment the Applet loads I get the error, is the exact same call so I don't understand why I get the exception using the Applet. I Also tried to call this from a Silverlight client and I was getting a security exception, this is where I found out about clientaccesspolicy.xml and crossdomain.xml, I added clientaccesspolicy.xml to the service and the Silverlight Client works great, so I decided to try crossdomain.xml and nothing, the Applet still does not work. I will put the stack trace at the end, thanks all for your time.

The exception is obviously caused by an HTTP 405 error, so it is the server, which decides that the client is not allowed to invoke the method. If it is an applet or a standalone Java application should not really matter. Is the applet and the standalone application perhaps accessing the server from different IPs and the server is configured to allow access from the IP used by the standalone app, but denying access from the IP used by the applet?
