Programming

Recently I was in urged to do a web project with the latest and coolest web framework Ruby on Rails. That's just one line of code grabbed from somewhere:       next if entry =~ /^\./ Ruby is said to read like a natural language, but for my eyes this is just a cryptic sequence. Maybe I have the wrong natural language. So to clarify what it means I translated it to some...

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...

EJB

I decided to write down the answer for some questions which my book's readers email me or ask me via twitter in my weblog so everyone can benefit from the answers. Here is the answer to the first question which involves custom security realms. GlassFish supports 5 types of security realms out of the box which are sd follow: File Realm: Usefull for development and testing purposes. GlassFish...

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...

The Book in Details: Security was, is, and will be one of the most important aspects of Enterprise Applications and one of the most challenging areas for architects, developers, and administrators. It is mandatory for Java EE application developers to secure their enterprise applications using Glassfish security features. Learn to secure Java EE artifacts (like Servlets and EJB methods),...

This is the first edition of a new column I'll be writing each weekend titled "java.net: the Week in Review." In the column, I'll present all of the previous week's Java Today news items, a selection of java.net blog posts, polls, and spotlights. I'll organize the presentation by categorizing the featured news items, so if, for example, your interest is JavaEE and GlassFish, you'll be...

What I realized shortly after we put out Magnolia 4.3 is that while we tried to explain new multisite support for example in this screencast there are still plenty of grey areas and lot of confusion when people actually get to use the multisite support. And I think I wrote and talked about this topic earlier as well. Of course as with any new functionality, there are still...

There are a number of folks (>500) who are now following this blog on Java.net, and a number who have gotten involved.  While we wait for more folks, we'll be researching new technologies, the first being NOSQL databases.  If the kind of topics we're research interests you, please feel free to join the project;...

JSR

I wanted to describe an interesting problem I recently faced that involved the most excellent JAX-RS specification and its Jersey implementation.  The quick overview is that we wanted the output of our JAX-RS resource classes to be client-agnostic, but we also wanted the ability to insert a decorator of sorts in between the objects we were returning and the normal JAX-RS serialization/...

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: 1) osgi-service.jar:...
