Hello,
I am using the following code in servlet's get method
res.setContentType("application/octet-stream");
ObjectOutputStream outputToApplet = new
ObjectOutputStream(res.getOutputStream());
outputToApplet.writeObject(mainHT);
outputToApplet.flush();
//outputToApplet.close();
In the APPLET I am using the following code:
try
{
String urlString = getDocumentBase().toString();
urlString = urlString.substring(0, urlString.lastIndexOf("/")+1)+
"servlet/"+servletName;
URL servletURL = new URL(urlString);
URLConnection servletConnection = servletURL.openConnection();
servletConnection.setDoInput(true);
servletConnection.setDoOutput(false);
servletConnection.setUseCaches(false);
servletConnection.setRequestProperty("Content-Type",
"application/octet-stream");
ObjectInputStream inputStmFromServlet =
new ObjectInputStream(servletConnection.getInputStream());
Object receivedObj = inputStmFromServlet.readObject();
inputStmFromServlet.close();
return receivedObj;
Hope this will give more insight to the problem.
Thanks
S
