Plugin not working the proxy

Question

I am working on a swing applet using the current version of the java plugin. Now everything seems to work when I run locally. But when I run of a client, the plugin is never loaded. Even the demos on the sun site do not load the plugin. We are on a intranet behind a firewall. All of the clients have the plugin installed and have converted the html page using the html converter.
Please advise

I;m experiencing similar problems with my swing based plugin based treeview applet.
My applet is loaded quickly however when it tries to contact the web server (through a proxy and a firewall) then it takes app. 7 minutes to reach the server and receive the result. When I enter the query into Internet Explorer the page is returned within a jiffy.
I've given my applet allPermission on the client side but still nothing. From what I read this should be a security problem but then why does a fully authorized applet still posts this problem.
Below is some of the code I use to connect to the server:
PrintWriter aWriter;
int i;
Vector theResponse;
String sResponseLine;
URLConnection aConnection;
theResponse = new Vector();
try
System.out.println("Opening URL: '" + anURL.toString() + "'");
aConnection = anURL.openConnection();
aConnection.setDoOutput(true);
aWriter = new PrintWriter(aConnection.getOutputStream());
aWriter.println("sTransaction=" + sCommand);
System.out.println("sTransaction=" + sCommand);
aWriter.println("&sClass=" + URLEncoder.encode(sSBClass));
System.out.println("&sClass=" + URLEncoder.encode(sSBClass));
aWriter.println("&lObjectId=" + URLEncoder.encode(sSBObjectId));
System.out.println("&lObjectId=" + URLEncoder.encode(sSBObjectId));
if(sCustomParameter != null)
if(sCustomParameter != "")
aWriter.println("&sCustomParameter=" + URLEncoder.encode(sCustomParameter));
System.out.println("&sCustomParameter=" + URLEncoder.encode(sCustomParameter));
aWriter.close();
System.out.println("aWriter.close();");
BufferedReader aBuffer;
aBuffer = new BufferedReader(new InputStreamReader(aConnection.getInputStream()));
System.out.println("new BufferedReader(new InputStreamReader(aConnection.getInputStream()));");
while((sResponseLine = aBuffer.readLine()) != null)
theResponse.addElement(sResponseLine);
System.out.println(sResponseLine);
aBuffer.close();
System.out.println("aBuffer.close();");
catch(IOException e) { System.out.println(e.getMessage());}
return theResponse;
The code hangs after the aWriter.close(); command
and continues 7 minutes later with the
System.out.println("aWriter.close();");
BufferedReader aBuffer;
commands.
Does anybody recognizes this problem?
