If all you need is to pass the applet initialization parameters, just write them into the applet tag param elements in the html page.

 <PARAM name="myparam" value="myvalue" > 

If you need to do it dynamically while the applet runs - this has been discussed a number of times here - search for servlet applet communcation.

Here is some code which i used for applet and Servlet comminication.
Hope this might help u.
/**
* This method causes the applet to interact with the servlet. Basically, the
* method writes the message to the servlet, then reads the response and sticks
* it in the "response" field.
**/
private void interactWithServlet() {
try {
// Create an object we can use to communicate with the servlet
String location = "http://pdc:7001/SP/AttributeServlet";
URL servletURL = new URL(location);
URLConnection servletConnection = servletURL.openConnection();
servletConnection.setDoOutput(true);
servletConnection.setUseCaches(false);
// Write the message to the servlet
PrintStream out = new PrintStream(servletConnection.getOutputStream());
out.println(topTextArea.getText());
out.close();
// Now read in the response
InputStream in = servletConnection.getInputStream();
StringBuffer response = new StringBuffer();
int chr;
while ((chr=in.read())!=-1) {
response.append((char) chr);
}
in.close();
// responseField.setText(response.toString());
} catch (IOException e) {
e.printStackTrace();
// responseField.setText("An error occurred: " + e.toString());
}
// Read in the message from the servlet
if(param_Request.getReader()!=null){
StringBuffer msgBuf = new StringBuffer();
BufferedReader fromApplet = param_Request.getReader();
String line;
while ((line=fromApplet.readLine())!=null) {
if (msgBuf.length()>0) msgBuf.append('\n');
msgBuf.append(line);
cat.debug("Applet servlet==================msgBuf:"+msgBuf);
}
fromApplet.close();
// Write the message back to the applet
param_Response.setContentType("text/plain");
PrintWriter toApplet = param_Response.getWriter();
toApplet.println("I (the servlet) received a message \"" + msgBuf.toString() + "\"");
toApplet.println("at " + (new Date()).toString());
toApplet.println("and sent this text in response. Hope you enjoy it!");
toApplet.close();
}
