Just now i wrote a first part of the series of jWebSocket tutorials or articles that will try to write to cover everything about jWebSocket from the source.http://blog.jwebsocket.org/2010/05/22/jwebsocket-step-by-step-part-1/

I used RPX service today in one of my random web application BookTwitts that i am trying to make it just for fun. RPX is pretty cool, it's a hassle to work on that very redundant work of user sign-in, maintaining profile etc. with RPX you can use 6 of the OAuth providers for free and the setup process is super easy.Now to handle the callback POST request from the RPX proxy with authentication

Looks like JDK7 as per Oracle could be the next release of Java Platform. One of the most interesting addition seems to be the addition of new bytecode operation for method invocation, which is 'invokedynamic'.invokedynamic bytecode operation which works more like 'inovkeinterface' but without the need to specify the return type and the target type of the method being invoked. This will release

I really like the idea of two-way full duplex communication between a user agent to a remote server, which is what defined by HTML5 WebSocket API. So I looked into it in more detail and i found it pretty interesting and i think it will be used widely for real time data transfer on the web. The Web Socket Protocol Document and Web Sockets API is pretty much enough to get the rough idea of

It's 1 a.m and i decided to give Spring Source new product http://www.springsource.org/roo a try and i must say i loved it. I find so pain to setup a normal spring based project from ORM to web layer and those configuration files, test setup, web.xml, urlrewrite.xml, applicationContext files and you know the list and of course dependency management with pom.xml. With Roo it was just few commands

Out of nowhere today i googled for opensource project by Nepalese and the result was not very convincing. I always knew about Nepalinux which is a skinned version of Linux for Nepali Language but not sure how many people use it and there are one or two others. Now, if we try to argue on this why there aren't any major open source projects by nepalese developers or companies believe me we can give

As Jeff Atwood mentioned in his famous blog article (http://www.codinghorror.com/blog/archives/001002.html) that there are only two kind of programmers :There are two "classes" of programmers in the world of software development: I'm going to call them the 20% and the 80%.The 20% folks are what many would call "alpha" programmers — the leaders, trailblazers, trendsetters, the kind of folks that

Ok, finally i got to the third part of this series to create a flex client. So in this part we'll create a flex project in eclipse and run it inside the server that we created in the part2.So in eclipse open the Flex Development Perspective and create a new Flex project as Give the name GettingStarted_GDS_Client. And select the application server type as J2EE. Now the next step is to setup the

mac book comes with Java 5 pre installed, so once you upgrade to Java 6 you will have trouble running eclipse since eclipse by default looks for Java 5. So to run eclipse with Java 6 you need to edit Info.plist file located somewhere around/Applications/ganymede/Eclipse.app/Contentsso open Info.plist in your favourate editor and uncomment the line to enable eclipse to use Java 5 installation.

i am working in one ecommerce project for almost more than 4 months now, and by now i have seen lots of UI bugs that actually happens in IE6 only, and these are the bugs that even a very good UI designer or developer hate to fix it, and one can imagine how much extra effort and money corporate has to invest on these so called IE6 bugs, Yes i know IE6 is still the most popular browser.

in my office we are working on a huge ecommerce project and off course we do use eclipse as an IDE , but eclipse being heavily loaded with various plugins and the amount of codebase that a workspace contains my colleagues often complains of eclipse being slow.By default eclipse uses 64MB by default as a heap space size, so we can increase that using the eclipse.ini file so this works really great

By general people i mean millions of users pouring and pounding just for fun, as now what's happening with all the social networking sites such as Facebook, Hi5, MySpace and many more.
