Here is an example of how to do single sign on.  This won't compile
because it has our own variables and stuff but it should help you out.
A few notes about things I saw in your code:
- I don't think you need the question mark at the beginning of the post
data.
- You need to do use the skipBody method unless you are returning the
info to the client.  The skipBody sends the body of the reply from the
remote server into the bit bucket.
- I also think you need to set the MIME type in your request.

Hope this helps,
Brian

Subject: Fwd: Try to Login


Hi all!

I use the jigsaw api to login into a site.
But if I try to request the server I get 
the following error:

Unable to contact target server www.mercedes-benz.de:80 after 1 tries

My sample code looks like this:

Request request = manager.createRequest();
String postdata=?username=USER&password=PASSWORD&btnSubmit=anmelden";
request.setMethod("POST");
request.setOutputStream(new StringBufferInputStream(postdata));
request.setContentLength(postdata.length());
request.setURL(new URL("http://www.mercedes-benz.de/portal"));
request.setUserAgent(USER_AGENT);
try{
     reply = manager.runRequest(request);
}catch(Exception ex){
		 System.out.println(ex.getMessage());
}

What I am doing wrong?

Thanks for any Help!!

Cheers!

Gregory
