Web Development Tools

As a test, I re-created the HRSystem application as described in the tutorial Developing Rich Web Applications With Oracle ADF. It's more than your basic Hello World application. For starters, the HR system application accesses a database. It also takes advantage of some sophisticated ADF features, such as graphs, page flows, auto-suggest, menu options to export to Excel and display in...

In my last blog post, I explained how to add versioning capability to templates. Being able to create, view and restore different versions of templates is great, but sometimes it's not so easy to see what has actually changed. And we might not be as lucky as having comments about the change from the author, or they might be cryptic to the point of being useless. So let's try and add the diff and...

Some time ago, I had the impression that everywhere I stepped in the endless Java universe, I came across rather outdated technology. Things that were hyped years back, but for some reason had been left behind by mankind in the course of time. Disenchantedly roaming that programming desert I almost went depressive looking at all the rusty wrecks of former featured APIs laying around all along....

Databases

Many of the Oracle Java development tutorials that access a database do so against the Oracle HR sample schema. See, for example, Developing Rich Web Applications With Oracle ADF. There are several approaches you can take to getting the sample schema installed in the Oracle Cloud, such as Using SQL Developer or JDeveloper as demonstrated in Shay's blog. In my case, we're going to run the SQL...

Programming

Operator Overloading by Chris Buckett, author of Dart in Action Overloading happens when you provide a new implementation customized to your particular class, which allows you to overload the common operators such as > (greater than) and < (less than). In this article, based on chapter 8 of Dart in Action, author Chris Buckett explains how this function helps you create truly self-...

J2EE

Whenever the JSF runtime needs to perform a conversion it uses a Converter to do so. As explained in previous blog entries you have the ability to implement your own Converter. But does that mean you need to implement it for simple conversions? No, you do not, the default JSF converters come to the rescue!   <b>Java Datatype</b>        ...

To facilitate component developers a convenience API was introduced to make it easier to implement the state saving requirements. Access to this API is made available through UIComponent.getStateHelper(). The API defines the following methods:   void add(Serializable key, Object value)   Object eval(Serializable key)   Object eval(Serializable key, Object defaultValue)  ...

After a long time away, I'm raising my head again on the java.net site. I once roamed these java.net streets as a JDK developer at Sun Microsystems, then as an end-user of the JDK while at a few startups, and now...well, I'm back again. This time, I've acquired years of J2EE experience, have created my share of SaaS and web service offerings, and have way too much to say about globalization of...

Distributed

I introduced myself to Konstantin Shvachko after hearing him speak in the Duke's Choice Awards BOF session at JavaOne 2012 (Hadoop was a 2012 award winner). Konstantin happened to be sitting right next to me in the audience, so before we exited the session, I asked him if we could arrange a chat before JavaOne ended. You've probably heard of Hadoop, but a great many likely don't know much...

JavaOne

I was pleased at JavaOne 2012 to have an opportunity to converse with JFrog founder Yoav Landman (@yoavlandman). JFrog, in case you're unfamiliar with the company name, is the inventor of Artifactory, the Java repository management solution that won a 2011 Duke's Choice Award. They also regularly produce cool swag tshirts (see below). Yoav was very busy at JavaOne 2012, but with advance...

In preparing for my JavaOne 2012 conversation with Java Champion Fabiane Bizinella Nardon, I was considering lots of questions about her work in the Brazilian health care system (her work as architect of what's considered the world's largest Java EE application won a Duke's Choice Award in 2005), about the state of Java in Brazil, about her co-leadership of Java.net's Java Tools Community, etc....

Linux

So I haven't posted a blog here since 2009 - and haven't work for Sun or Oracle since early 2010. It's been a wild few years working on a number of things as diverse as giant clouds to control software for cameras which go down oil wells. And I have a new blog at timboudreau.com, naturally using a blog engine I wrote myself (I gave myself a project to learn node.js). Currently I'm architecting...
