Plugin hangs when prompting for network password

Question

Hi all,
Here is a summary of what happens :
The plugin hangs after displaying the dialog box for the
username / password for the firewall connection.
No exception is shown.
The applet is signed.
This occurs with Plugin 131 and 1.4
Code sample here :
URL url = null;
InputStream is = null;
URLConnection conn = null;
//Connect to the URL.
if (!_httpsFlag) {
try {
     // Open it up.
     is = new URL(request).openStream();
_httpsFlag = false;
catch (Exception e) {
try {
url = new URL(reqHttps);
conn = url.openConnection();
is = conn.getInputStream();
_httpsFlag = true;
catch (Exception e2) {
e2.printStackTrace();
     showMsg(noWebServerMessage);
return null;
else {
try {
url = new URL(reqHttps);
conn = url.openConnection();
is = conn.getInputStream();
catch (Exception e) {
e.printStackTrace();
showMsg(noWebServerMessage);
return null;
If someone has an idea of a solution to this, please help !!

Answer 1

Just for the record :
I sorted this one by creating a dummy connection before instanciating the graphical components of the applet.
The network prompt behaves properly if I do that.
