Beyond being merely a computer programming language, Java is the most widely used software platform in the entire world. There is a large number of various software solutions that were developed using this technology. Without many people being aware, Java is present in our daily lives in embedded technologies like blue-ray discs and a countless number of sites on the internet that...

Embeddability of GlassFish is been around for quite some time now. In 3.1, the embeddable APIs have been revised. Most of the GlassFish community is already aware of the API revision, however I would like to briefly describe the revised APIs in this blog and welcome any feedback. Embeddable API overview: API JavaDocs are at The APIs are briefly...

We are making progress on the next release of Leonardo, an open source desktop Java drawing program. One of the key features scheduled for the next release is a webservice that lets users save and share reusable symbols they've created. For example, someone could create a set of GWT mockup widgets, then share this set with others. The challenge I face is that I'm mainly a client side developer....

Next week I will be presenting a free webinar about Java EE 6 and Glassfish 3.1. The title can be translated to English as: "Java EE 6 and Glassfish 3.1: Simplicity + Ligthness = Productivity". The reason the title is in Portuguese is because this will be a webinar targeted at Brazilian Java EE and Glassfish users - as far as I know it will be the first webinar in Portuguese on these...

The JSF 2.2 ballot was approved, so now it is time to start speaking up about what you think needs to be in JSF 2.2. Obviously it takes a bit of time to start organizing the Expert Group. But nowadays individuals can join too. So there really is no excuse to start contributing. If you do not know how to get started feel free to comment!

Recently, we've enabled a "view" to simplify the monitoring of JSF automated tests through the Hudson framework. The introduction of clustering support in GlassFish has expanded our JSF automated test suite coverage. The URL for the view is: On a side note - and redirect to

How would you mock your services which are not mock-friendly? Let’s introduce a real case (the bad one) with some preconditions: You have a service where DAOs are wired at runtime based on the some conditions. DAOs lookup API is private and not exposed to the caller In this case you will be blocked from mocking those DAOs because of such approach. The solution I came up with was to tweak the...

JSON JSR(pre JCP filed draft) As announced earlier, Oracle wants to include a Java API for JSON in the Java EE platform. I have circulated the Java API for JSON JSR draft internally in Oracle.

The planned scope for this API is: Produce and consume JSON...

I know what you are has always been a service. But the Cloud is making it evolve. Cloud Computing has been one of my favourite topics in the last couple of years. Coming from a sysadmin background I am frequently in awe of how easy it is nowadays to conjure up vast amounts of computing and storage resources out of thin air. Of course I know that its not "out of...

Often code has a bad smell, then it gets time to replace custom lines by common patterns. Sometimes it even makes sense to even replace a single line of code by a class just wrapping that single line (which actually increases code size), if that makes readers better understand what the code does. Unfortunately often such patterns are publicly known but do not exist as ready to...

Meanwhile I am looking back to more than 25 years of programming, and more than a decade I spent in a very sensible area where quality (in the sense of zero failures) plays a big role. So call me "sensible" for quality. For long years "we" (i. e. developers) had hard work to do using simple command lines tools like vi etc., but meanwhile there are great, even free,...
