I thought of updating the instructions; hence this blog.

Here is the outcome...

This is in addition to it being able to run on its own runtime, i.e., HK2. Since I have been involved in this effort from the very beginning, I will be blogging about it in days to come. Today is just the start.

Those of you who don't know what is HK2, it is the short name for "Hundred Kilobyte Kernel," HKK further reduced to HK2. It is being used in development of ultra light weight, modular, next generation GlassFish application server. HK2 is not just meant for GlassFish or application server type applications; any Java SE programmer can use it to write modular applications. It has a very nice component model with IoC support.

To complete the story, this time I will share my maven experiences.

While writing this compiler plugin certain things did not behave the way I was expecting. I will talk about them in two parts. In this part I will talk about Java related issues. ss141213 2007-11-27T09:40:20-08:00 http://weblogs.java.net/blog/ss141213/archive/2007/11/a_javac_plugin_1.html Java Persistence API specification requires its users to not only provide a persistence.xml file but also enumerate managed persistence class names in that file. In this article, I talk about a Java compiler plugin that can create the persistence.xml file for you automatically during normal course of Java code compilation and show how easy it is to use in your existing build scripts - be it maven or ant or shell script.

GlassFish team of Sun Microsystems, which participate in one of the most important open source efforts initiated by Sun Microsystems, will not only talk about GlassFish & Java EE platform, but will also have a live demo running at their booth. This blog gives details about the demo that's going to be shown their.

Using a very simple Java EE application, this article shows how to achieve this in an elegant and portable way. The technique described here is completely portable across any Java EE 5 compatible application server because it uses a standard feature called *persistence context propagation*.

Earlier we had shown how to use Hibernate and Kodo in GlassFish. Now it's time for OpenJPA. I thought I shall give a try using it in GlassFish. This blog reinforces the fact that it could not be easier to plug in a third-party persistence provider in GlassFish.

Earlier we had shown how to use Hibernate in GlassFish. Now it's time for Kodo, which is another high performance & popular O/R mapping solution. Recently Kodo 4.0GA was released and it supports Java Persistence API. So, I thought I shall give a try using it in GlassFish.

This is largely because of activities happening in more than one branch in CVS. I will try to respond to the confusion here.

It can be used in three types of containers, viz: ejb container, web container and application client container. In this blog, we will talk about using this API in application clients. We also discuss two different way of packaging the application.
