Using a MultiActionController as a Web Service

[salva]

Hello,

I have a producction system working on a JBoss server. Part of the system is working in this way:

I have a lot of clients requesting a web page and processing the response (Ideally this would be a Web Service, I'm waiting for Spring Framework Web Services). This is the client code (this is a fragment):

/************ Client *****************/
private URL url;
private URLConnection urlConn;
private DataInputStream input;

url = new URL("THIS IS A REQUEST TO A WEB PAGE");
urlConn = url.openConnection();
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type", "application/html");
input = new DataInputStream (urlConn.getInputStream ());
if (input.available() != 0) {
input.read(resultado);
}
input.close();
urlConn = null;
/************* We process "resultado" ***************/

This is the server part...

/***************************/
public ModelAndView paqueteNuevo(HttpServletRequest request, HttpServletResponse response) {
// Params
String terminal = request.getParameter("terminal");
try {
response.getWriter().write("RETURN STRING");
}
catch (IOException e) {
logger.fatal("Error." + e.getMessage() + ")");
}
return null;
}
/**************************************/

I return a null value as a ModelAndView....

Sometimes JBoss stops responding... If I undeploy the App JBoss works again, then I deploy the App again and it's working the right way for two or three days... Any idea what's working wrong?

Thanks in advance.

PD: Sorry for my English...

More information:

When everything is working the right way this is the end log for a request:

/*********************/
2006-01-09 14:07:57,355 DEBUG [org.springframework.web.servlet.DispatcherServlet] Null ModelAndView returned to DispatcherServlet with name 'xxxx': assuming HandlerAdapter completed request handling
2006-01-09 14:07:57,355 DEBUG [org.springframework.web.servlet.DispatcherServlet] Successfully completed request
/***********************/

Then I have 250 request without response. This is the log in this case, there is no response...
