Hi,
Here is my code snippet:
Servlet:
public void doGet(HttpServletRequest req, HttpServletResponse res) throws
ServletException, IOException{
Hashtable mainHT = new Hashtable();
mainHT = processSelect();
res.setContentType("application/octet-stream");
ObjectOutputStream outputToApplet = new
ObjectOutputStream(res.getOutputStream());
outputToApplet.writeObject(mainHT);
outputToApplet.flush();
//outputToApplet.close();
}
Applet:
public Object receiveObject(String servletName)
{
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;
}
catch(IOException ioe)
{
System.out.println("Exception ioe");
System.out.println(ioe);
ioe.printStackTrace();
return null;
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
}
Hope with this some one can throw some light on the problem.
I am having all the class files of applet in the public_html directory and
servlet's class file is in servlets directory of the web server.
TIA
