Java: client, client, (threaded) server, streams client info, JPanel created but messages(?) block start of game
by tanknique in Development Tools & Services

I am developing a small scale client1/ client2, server (threaded) TCP game. In trying to deal with latency issues I've realised there were flaws in my transmitState(). It was forcing unnecessary info down the comms streams creating sluggishness, leaving cars in different places in the JPanel, and was basically just wrong. So I took it out.

But in doing so I

Java: Server/Client -> Client/Client
by Josh Freed in Network & Servers

I want to set-up a peer to peer connection between some computers, so users can chat and exchange files without an external Server. My first thoughts were as follows:

I make a central ServerSocket on a server, where all applications can connect to. This ServerSocket keeps track of the connected sockets (clients), and gives the IP and Port of a new connected client to all other clien

I have a Android REST Client, but no a web service implemented. What can I do to send to the client a set of images from a server?
by doctorbigtime in Android

The question is about how to perform a client-server communication for an android app.
The client uploads a image. The client is implemented using REST
But the server has to send a set of images. Which is the best method. Have any examples?
Later I want to represents these images in the android app.


RMI calls not working when firewall present on the WindowsXP client, but fine on Windows 7 client
by Sankarsan Bose in Programming Languages

I am using the basic RMI-based client/server app shown in Java Tutorials. I am running the server and client on different machines. I also export the remote objects for both the server and client, and make them available to each other.

However, there is a firewall turned on the client side and so the RMI calls fail (from client to server or server back to client). Also, when

DAL/BLL and Client/Server: Should the client use BLL or DAL objects for presentation? Or maybe another layer (data transfer object?)
by snackie in Coding

I'm writing a client/server system. The server has a DAL/BLL design. The client is responsible for presenting the data objects and providing dialogs and wizard to allow the user to update these objects (i.e. adding/editing a user).

Initially I thought I'll just make the DAL objects have a universal data provider object so they can be used by the client as well as the server. For

Java Client unable to create event in google calendar without client library
by xeemzor in Development Tools & Services

I am trying to write a simple java client which can create an event in my google calendar WITHOUT using client side libraries.

Here is my code but I am unable to get dataoutputstream to send the event related details to the server :

URL siteUrl;
try {
System.setProperty("javax.net.ssl.trustStore", "/home/yashdosi/wso2esb-4.0.3/repository

In Bootstrap Protocol, how does a client know if a hardware broadcast is intended for another BOOTP client on the same physical net?
by terrestris in Programming Languages

When a bootp client receives a reply via hardware broadcast, how does it know whether the reply is intended for another BOOTP client on the same physical net?

Revisit Client/Server Model. Should the client interact with the database directly?
by avi in Programming Languages

I thought about it and technically you could use databases tables and temporary tables/database views directly from a client.

So wouldn't it be more efficient for the client to interact directly
with the database as opposed to using a tiered architecture?
What are the cons?
Are there any libraries/frameworks in Java that help do this

Here is a demo

RPC to send varialbe from server to client on client joing game Unity
by Tristan in Network & Servers

Ok so I have this network script that works really well except for when I want to spawn a player at a different location. Im basing location on the number of current players connect. Right now the variable is updating right on the server so that good. But when a client joins the game, the player count for him is 0. I want to set that to the current number of players connected from the server va

Google Maps JS API v3 - Do I need to include the CLIENT parameter on client side requests?
by markku in Development Tools & Services

I'm working on a client's website that has retail stores. This client has a Google API for Business account, CLIENT id and currently uses the web services API in the backend of their website.

We are now adding the store locator and want to embed the Client-side JS API [v3] into the public facing [for profit] website. We will be embedding the store locator in the pages using this sc
