Hello everyone,
I have the following code on the applet side:
URL servlet = new URL(appletCodeBase, "FormsServlet?form=requestRoom");
URLConnection con = servlet.openConnection();
con.setDoOutput(true);
con.setDoInput(true);
con.setUseCaches(false);
con.setRequestProperty("Content-Type", "application/octet-stream");
ObjectOutputStream out = new ObjectOutputStream(con.getOutputStream());
out.writeObject(user);//user is an object of a serializable class
out.flush();
out.close();
ObjectInputStream in = new ObjectInputStream(con.getInputStream());
status = (String)in.readObject();
in.close();
if("success".equals("status")) {
JOptionPane.showMessageDialog(rootPane, "Request submitted successfully.");
} else {
JOptionPane.showMessageDialog(rootPane, "ERROR! Request cannot be made at this
time");
}
In the servlet side I recieve the code as follows:
form = request.getParameter("form");
if("requestRoom".equals(form)) {
String fullName, eID, reason;
UserRequestingRoom user;
try {
in = new ObjectInputStream(request.getInputStream());
user = (UserRequestingRoom)in.readObject();
fullName = user.getFullName();
eID = user.getEID();
reason = user.getReason();
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/chat_applet","root","");
PreparedStatement statement = con.prepareStatement("INSERT INTO REQCONFROOM VALUES(\"" + fullName + "\",\"" + eID + "\",\"" + reason + "\")");
statement.execute();
out = new ObjectOutputStream(response.getOutputStream());
out.writeObject("success");
out.flush();
} catch (Exception e) {
e.printStackTrace();
out = new ObjectOutputStream(response.getOutputStream());
out.writeObject("fail");
out.flush();
}
}
When I click on the button that calls the code in the applet side, I get the following error:

Why am I getting this error? I have flushed when I output, I have closed the connections also, yet I get the error. Any reason for this?
