Question

i am trying to use RemoteServiceServlet with Filter to catch the request to track what methods are requested in my webapplicaiton of a user.

i am unable to do this…

can anyone suggest a best way to track the methods called something like a ServletFilter.

NOTE i like to track user and his request he requested for.

You can override public boolean preProcess(HttpExchange exchange) in your implementation of RemoteServiceServlet as follow.

public boolean preProcess(HttpExchange exchange) {
    String body = null;
    RPCRequest req = null;

    // Read and parse the request
    byte[] bytes = null;
    Object bytebuf = getAttribute("RequestBody");
    if ((bytebuf != null) && (bytebuf instanceof ByteBuffer)) {
        bytes = ((ByteBuffer) bytebuf).array();
    }

    if (bytes == null) {
        setAttribute("ResponseCode", new Integer(500));
        setAttribute("ResponseBody", "Missing Request Body.");
        return true;
    }

    body = new String(bytes, "UTF-8");

    req = RPC.decodeRequest(body, this.getClass());

    String methodName = req.getMethod().toString();
    //Here you have name of a method
    //You can get parameters
    //Object[] parms = req.getParameters();
    return true;
}
