Just recently I was engaged to assist with an application that wasn’t behaving. The application, running in a 1.7.0_45 JVM, relied heavily on a 3rd party SAAS framework. That vendor provided my client with a list of 26 different JVM flags that should be set. When faced with this long list of flags I couldn’t resist asking why all the flags and why these flags. After all there are more than 700...

I was very pleased to see the JFrog team take me up on my suggestion early this year that "Maybe the JFrog team will consider giving a presentation on how they put all this together at JavaOne this September". Unfortunately for me, the session (Building a Massively Scalable Cloud Service from the Ground Up) was already filled to capacity as I walked up to the door, so I was unable to attend....

What happens if you configure a Hadoop-centric scalable big data infrastructure running on the Amazon EC2 cloud, that's programmed to perform some very basic processing on delimited ASCII data records (about 30 characters in each record), and you feed it a single data record? How quickly do you think that massively powerful system would process that teensy, trivial input data set? Milliseconds?...

Government... Isn't interacting with it your favorite social pastime? What? It's not? OK, so what don't you like about it? What? You're saying that, in your country, you can't just log into your favorite government sites and experience speedy, reliable, secure services?
I'll guess, then, that you must not live in Ecuador... Poor you!
But, don't feel too bad. From what Java Champion Jeff...

At the JavaOne 2013 Java Technical Keynote, there was a series of demos of software that enables two people to play chess, using some of Java's latest features, including Java EE 7 Websockets, many variations of Java 8 (recent weekly builds), Lambda Expressions, Java ME, Embedded Java, ... It was an impressive demo of many of Java's recently-released and not-yet-finally-released capabilities,...

I will be presenting the following sessions at Silicon Valley Code Camp 2013. For those in the Bay Area, Silicon Valley Code Camp is on Oct 5,6 2013 in Foothill College, Los Altos. It is a very well organized conference by the developers for the developers. This year has 232 sessions and 4500 registrations and am always amazed at the way Peter Kellner and his team pull this off!
These are my...

According to research, most complex report development work can be simplified by performing the data source computation in advance. For example, find out the clients who bought all products in the given list, and then present the details of these clients.
In developing such reports, it is the “computation” part and not the “presentation” part that brings about major difficulties. In which stage...

If you are having a problem with your JPA queries and you are trying to understand what SQL queries it actually sends below the covers you can configure the JPA runtime to show the actual SQL statements it sends over. How? Well for EclipseLink you would add the following to your persistence.xml file.
<property name="eclipselink.logging.level" value="FINEST"/>...

a little discussion in a television series here that i am the speaker. the topic is Java. The host, TV Excelence, said any update for Java and why Java is silence now.
I said there are Java worlds which use Java but we cannot said it is Java, but use Java.
1. BigData with Hadoop under Apache , is a new ecosystem that based on Java.
2. Smartphone/Gadget with Android under Google with Apache...

I’ve been talking about JSF 2.2 new features out on the conference trail for quite a while now. I usually talk about the big three: Flows, Resource Library Contracts, and HTML5 Friendly Markup. This blog entry talks about another, mostly behind-the-scenes, feature: ClientWindow. I introduce the concept of ClientWindow and give a simple example illustrating one solution to a common web...

My JavaOne 2013: Wrapup
This blog entry summarizes my session participation at JavaOne 2013. I plan to update this entry with links to the content on Parleys.com as it becomes available.
Sessions I Attended
In general, speaking more than listening is a very bad way to live. I find this holds true at conferences as well. Here are the sessions I attended. I attended eight and presented six, so I...

Recently, I was asked to participate in creating another Java application at my company.
It was to be our team's third major Java application since 2002.
We felt we had plenty of wisdom from our previous two Java applications to apply to our third one.
One of our first steps was to form an application architecture sub-team.
This sub-team's purpose was to provide the development team with a solid...

My company uses a large number of software applications to support all aspects of its business.
These software applications are either "bought" or "built".
The portions of the company that cannot be supported by purchased software are
supported by custom developed, in-house, applications.
A variety of technologies are used to create and build these custom applications.
The Java framework has been...

A while ago, I was asked to evaluate another Java application that was being used at my company.
It was a point-of-sale app, developed entirely "in-house" by one of our overseas affiliates.
I wondered what their MVC model would look like.
How different would their Java app be from the ones I have worked on?
I started my evaluation by learning all I could about the architecture and design of this...

Web Services and XML
Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. JAX-RS provides a standardized API for building RESTful web services in Java. This example will show how to...
