In the competitive world, enable the service as a business value can be so damn critical for the company success. The problem is how does the company must spend their effort and money to makes the system ready in the fast time-to-service fashion way ? since i believe that software are now realized as being commodity product, then it would be possible to solve those issue. Such SugarCRM which is bring a brilliant functionality which is comes free for the business user.
Based on this idea inspired me to give a tutorial and share my experimental works on Deploying CoolStack in OpenSolaris and enabling the SugarCRM application as your CRM business services.
Please find out for more detail the presentation slide within OSUG indonesia website bellow:
The presentation also explain how we manage to integrate our application with SMF in OpenSolaris
Its been great experience meeting with Sun Asia South Country team and spend times together to get the Sun Asia South direction for this year.
Its been very surprisingly great experience and achievement (Award for Technical Excellence 2008) i had receive from Sun Microsystems Asia South this year 2008 (http://sg.sun.com/sunnews/events/2008/partnerkickoff/awards.jsp), as part of the IT Architect staff from Sun Microsystems Indonesia.
My special thanks to Silvia Rivena Wibowo as my ITA Manager, Andre Wenas as a Technical directors, and all of my friends within Sun Microsystems Indonesia who helped me to achieve this award.
This process makes me realize that “The Problem is the Opportunity, Think out of your box and be humble “.

Have you ever imagine that your office only as big as your computer screen ?
Check out nice project called Project Wonderland. Basically this project build on top of Project Darkstar and utilizing IMS (IP Multimedia System). They are using 3D presentation to simulate the office environment and virtually bring the office into your desktop.
for the detail information check out bellow site link:
Download the movie and wait until the middle of movie, its enlighten.
Few weeks back, its very interesting for me to have a meeting with one of mobile operator provider. The topic of that particular meeting was discussing about IMS (IP Multimedia Subsystem), basically we are trying to find out how does the mechanism of the IMS itself. After awhile with some experiment i found out that IMS works using IP communication between devices called RTP, and uses SIP Module as their call control. With a little experimental i have conduct, i would like to give you some of information that you might interesting on exploring this technology.
Call Control / SIP Module:
there is quite good demo on that site of how the SIP module works and establish IP communication such as VoIP using the SailFin server.
During the experiment i also have a problem to install the SIP client software for that particular demo so i suggest if you have windows vista on your hardware try ExpressTalk software for your SIP client software.
JavaFX is a scripting language that provides more powerful client applications in term of features for the user interface experience as well as being incorporated with server platform technology such as RMI, Web Services, and EJB. Its ability to reuse all Java libraries opens an opportunity for JavaFX to create flexibility and ease the integration and reuse of existing Java applications. Take a look of this article to guide you step-by-step JavaFX development and integrate with EJB Technology http://java.sys-con.com/read/478360.htm.
Referring to what was Grady Booch (one of IBM fellow, to whom i learn so many things indirectly) statement EVOLUTION is the best way to improve the IT not REVOLUTION. I try to correlate this statement with day to day development in Java (especially Java Virtual Machine) shows that Java Technology is the most consistence programming language on planet earth, since we know that with even newer version of JVM like mustang still give you capability to run basic java code that you have developed from recent version of JVM.
Recently i was amazed with on-going tools development that reach many element of Software Development Life cycle, Sometime when we learn code development we will end up on some question “am i doing something right and according best practice ?”. With nowadays development tools with extra ordinary feature such as code review plug-in give me an idea on how to ease my job doing code review static analysis, and at least reduce my simple simple mistakes that might causes performance problem later on. So far there is two plug-in that i was experienced during the code review, PMD is an open source plug-in that suitable for the most Java Editor you can find on planet earth, and Static Analysis Code Review from IBM Rational Software Architect. Hopefully this feature will bring you to the next level of doing code.
Three common problems related to the java application performance can be categorized into three types:
- High CPU Contention
- Memory Leak
Sometimes its really really hard to find the object that causing those problem, but with nowadays feature for heap profiling since jdk1.4 help us to identify our root problem.
usually we can run those feature using -XX option, for example:
java -Xms32m -Xmx64m -Xrunhprof:heap=dump,monitor=y,cpu=samples,thread=y,file=<dir>
with those option we can snapshot statistic of the JVM behavior and analyze the result with your favorite tools. Based on my experience of troubleshoot the application usually i use two tools IBM HeapAnalyzer (tool to identify the memory leak problem), and PerfAnal (tool that provide an analysis of CPU contention problem).
I think it become more and more obvious, that developing application with Java will give you a full control of the application itself.
