Web Services and XML
Recently a user in GlassFish forum asked about developing JAX-WS web service in an OSGi bundle. Here is a complete sample demonstrating a JAX-WS web service invoking an OSGi service via OSGi service registry. You can download it from here. The diagram below hopefully explains the organisation of the sample:
As the above diagram shows, we have three components, viz:

Manage, Administrate and Monitor GlassFish v3 using Application Server Management Extensions (AMX) & The Java Management Extensions (JMX)
Management is one of the most crucial parts of an application server set of functionalities. Development of the application which we deploy into the server happens once with minor development iteration during the software lifecycle, but the management is...

During implementation of the NTLM authentication into our application, I wanted to achieve failover to standard login page (html form) if NTLM authentication fail.

I'v migrated code from spring-security 2.0.5 to be able to use NTLM on spring-security 3.0.2. NTLM isn't supported anymore official by SpringSource but after some refactoring I was able to use NTLM without problems.

I will wrap up my experience at eclipsecon. This was my first time at eclipsecon. Folks who had been here earlier told me that this year there was a lot of topics around eclipse runtime projects – so the focus has shifted from tools to runtime. Overall I liked eclipsecon.
My topic, OSGi & Java EE in GlassFish, was also of the same type. The slides of my talk are...

Extending GlassFish CLI and Administration Console, Developing the sample Modules
Administrators are always looking for a more effective, easier to use, and less time consuming tool to use as the interface sitting between them and what they supposed to administrate and manage. GlassFish provide effective, easy to access and easy to simple to navigate in administration channels which cover all...

As promised earlier, I am going to quickly go over the key points I gathered from the talks I attended at eclipsecon and I also want to brief you about my topic at the conference. Because of a migrane attack earlier today which I firmly believe was caused by severe jat lag, I could not attend as much on day #2 as I had earlier decided to, and that's the very reason why I will keep...

Modularity is the essential design and implementation consideration which every software architects and designers should have in mind to get an easy to develop, maintain and extend software.
GlassFish is an application server which highly benefits from a modularity system to provide different level of functionalities for different deployment and case studies. GlassFish fully supports Java EE...

Have you ever got into the situation where you feel like you need to stretch the limits of HTTP form processing?
Sometimes when developing complex web applications you end up with a form that has just too many features on it. This situation is particularly common when the application uses Ajax forms, as these forms often end up accumulating an enormous amount of funcionality - different actions...

Have you got magnolia-4.3? Setup multiple sites? All right, you are all done. The only thing left is to observe the load on the server and how many requests you can serve. You might have noticed that after activating the content, load on the public is bit higher even though there is no increase in traffic.
Why? Simply because after activating the piece of content, cache on the public...

Last bunch of the entries have been all about the code. Today let's try something different. Partly because at the time of writing I'm just 34 thousand feet above Atlantic and really don't feel like coding anything, but partly also because i have been thinking about the problem I'm going to describe for while already.
I'm sure most of you have seen similar issue in the past as well or are...

I wrote about Magnolia cache few times already since it have been re-implemented for Magnolia 3.6. And it seems like with Sprint 4 of Magnolia 4.3 it came back to bite me.
There was a bunch of tickets related to various aspects of the cache. Most of it was related to the fact that the default cache key (only URI) was not enough for many installations which were...

Last time we looked at writing command and shortening the URLs using simple TinyURL API. This time, lets try to take this one step furter and generate URLs that are mobile-users friendly, i.e. URLs that can be easily recognized and processed by various mobile devices. Such are urls in QCode or DataMatrix scan codes.
I'm sure almost everybody have seen those somewhere already, be it on printouts...

At the very beginning of my full time programmer career, when I worked at Silicon Graphics, Larry Wall and Randal Schwartz gave a brown bag session about their now legendary camel book. Naturally, I had them sign my copy, the front page of which I proudly display at left. Notice the “There’s More Than One Way To Do It!” stamp at the top. For better or worse, Perl is famous...

Meeting with OSGi Experts
Although I had interacted with a number of active members of OSGi  expert group, last week I had the opportunity to meet some of these experts at an OSGi Enterprise Expert Group face2face event held at LinkedIn's Mountain View office. This is also the first time I met Richard S. Hall, the Felix guy (don't confuse with a very active Felix ...

There are times when things hurt so much that you feel urged to blog about them once solved. This is one of them.
Our company is using XSL heavily for reporting (generating vector charts in PDFs on the fly from data analyzed by GlassFish), so it is not very amazing that we found some bugs in the XSL transformer (a.k.a "JAXP Implementation") contained in GlassFish. As we're not so fast...

Talking about messaging imply two basic functionalities which all other provided features are built around them; these two capabilities include support for topics and queues which basically lets a message to be consumed by as many interested consumer as subscribed or at just one of the interested consumer(s).
Messaging middleware was present in the industry before Java come along and every one...

I woke up the other day and realized its 2010. When I was a kid, year 2000 was far, far away (well not quite, but hey when you are 7 years old 13 years is a long time).
In 2001 we were supposed to be colonyzing the moon. In 2010, Jupiter would be within our reach. And there are reliable reports indicating that 9 years from now flying cars and aritificial life forms...

A big part of my current company work is related to managing infrastructure hosted in cloud computing environments. I have recently released an open source project (Rain Toolkit) to help ease the management of Amazon EC2 objects. It is a set of command-line tools for performing day-to-day administration tasks.
Since Rain Toolkit deals with the management of EC2 resources, it seemed only...

For meanwhile more than 25 years I am writing computer programs. More than a decade I spent with programs accessing databases, virtually always relational ones. I soon learned that this is rather hard work. Not only that you need to know about the theory behind RDBMS iself, but also you need to know the technical APIs (like ODBC, ADO, RDO, JDBC, JDO, JPA, CMP, ...), the structure of...
