Problème communication applet / servlet (struts)
Bonjour,
J'essaie de faire communiquer mon applet avec une action struts. Le problème c'est que j'ai l'impression que ma servlet n'est jamais appelée car j'ai mis des logger à l'intérieur et je ne retrouve pas les traces...
Voici le code de mon applet:

throws MalformedURLException, IOException {

URLConnection con = urlServlet.openConnection();

con.setDoInput(true);
con.setDoOutput(true);
con.setUseCaches(false);
return con;

try {

oos.flush();
oos.close();

String result = (String) inputFromServlet.readObject();
inputFromServlet.close();
instr.close();
// show result
System.out.println("Result servlet: " + result);
