JBOSS 4.2.0 GA and local socket connection

jova73 Sep 7, 2007 10:16 AM

Hi,
I'm testing our application with JBoss 4.2.0 GA (AIX 5.2 and JDK 1.5.0 IBM) and I have a problem with a socket connection: a class running in the web container (JSP custom tag class) opens a socket to a servlet running in the same container but the connection fails and the client class gets

java.net.ConnectException: A remote host refused an attempted connect operation.

The same app runs without problems on the same server with JBoss 3.2.1 (and JDK 1.4).
I solved the problem changing the application architecture: I replaced the socket connection with a method call and now everything is ok, but I'd like to understand why the local socket connection didn't worked...

Any idea?

Thanks in advance,
Andrea

How do you open the Socket connection? Can you post the code? Do you use the IP of the server to open the connection?

Hi Jaikiran,
here's my code:

String urlPath = "http://127.0.0.1:"
 + pageContext.getRequest().getServerPort()
 + request.getContextPath() + "/myservlet";
URL url = new URL(urlPath);
URLConnection connection = url.openConnection();
String cookie = request.getHeader("Cookie");
connection.setRequestProperty("Cookie", cookie);
connection.setRequestProperty("charset", "ISO-8859-1");
connection.setDoOutput(true);
OutputStreamWriter ostream = new OutputStreamWriter(connection.getOutputStream());
BufferedWriter out = new BufferedWriter(ostream);
... // write something to the servlet
out.flush();
out.close();
is = connection.getInputStream();
... // read servlet response

Thanks!
Andrea

Try with localhost:
String urlPath = "http://localhost:" + pageContext.getRequest().getServerPort() + request.getContextPath() + "/myservlet";
