I have been trying to get my first Restlet app up and running but I am running
into a problem. Hopefully I will be able to explain what I am trying to do and
what is happening in an understandable way. I have created a ServerResource
class that will be called when a user goes to the route
"/Identifier/{identifier}".
When in this class I want to take the variable being passed in which is
"identifier" and then pass that variable into another method that sends an XML
request to a server, gets an xml response back and then pass the xml response
back to the client. So far I have been able to get that to work with the code
that is below. What is happening is when I put this into a browser to test it
http://localhost:8182/Identifier/identifier it works for the first request that
I send in. The problem is that if I were to put in "Jason" in as the identifier
for the first request I would get back the response that I am looking for, but
if I then were to put in "George" in the request so that it looked like
http://localhost:8182/Identifier/George I am getting a null response back.
Is there some type of reset option I have to do in the ServerResource that
allows me to make a new call to it? It is almost as if it can only do the
request once and then it is locked to where I can't call it anymore.
I hope the above makes sense. Below is the code that I am trying to accomplish
the above with.

boolean eof = false;
while (!eof) {
xmlResponse = in.readLine();
if (xmlResponse == null)
eof = true;
}
csgold_socket.close();
} catch (IOException e) {
//System.out.println("IO Error:" + e.getMessage());
}
System.out.println(xmlResponse);
return xmlResponse;
}
