There are three ways to communicate from an applet to
servlet and they are :

a) HTTP Communication(Text-based and object-based)
b) Socket Communication
c) RMI communication
(u can say by using URL object open the connection to
server and get the InputStream from URL connection object)
Steps involved for applet-servlet communication:
1) Get the server URL
URL url=new URL();
2) connect to the host
URLConnection Con=url.openConnection();
3) Initialize the connection
Con.setUseCatches(false);
Con.setDoOutput(true);
Con.setDoInput(true);
4) Data will be written to a byte array buffer so that w
can tell the server the length of the data.
ByteArrayOutputStream byteout=new ByteArrayOutputStream();
5)Create the outputStream to be used to write the data to
the buffer.
DataOutputStream out=new DataOutputStream9byteout);
