Java Card provides an environment for Java applications to run on smart cards. The Java Card Specification 3.0 provides “enhanced execution environment, a new virtual machine, and new network-oriented features”. So this is something I definitely have to check out when I get some free time to look into mobile device technology. Well, I can think of a few reasons to see what this technology can do from my point of view and I am definitely interested in finding out more. This is definitely something that I think I will set up as a Tampa JUG presentation later this year.

A friend of mine, Vladimir Vivien, has done something really cool and very useful with JMX and Groovy. He has created a Groovy JMX Builder. For those of you who are not familiar with Java Management Extensions (JMX), it is a core J2SE 5.0 feature that allows direct access to your exposed classes at runtime for monitoring and management. For those of you not familiar with Groovy, it is a dynamic scripting language that runs on the JVM and it supports Domain-Specific Languages which allow you to write more succinct code to do more with less. So if you put Groovy and JMX together you get monitoring and management of your code at runtime minus the overhead of learning all of the implementation details of the technology, like JMX. If you are writing Groovy code, you should go check it out.

Well I decided to post a screen shot of Tangerine’s Product Manager. I am still working on the Flex front-end but most of my Grails back-end is in place for now. I think Flex is a great technology for creating Rich UI’s with little effort. I have been working with Flex for a few months now and I think that it will definitely be something that development shops will have to consider when moving forward with a new project.

The Grails back-end is probably less complex(to me the developer) than the Flex front-end. When you have the power of Spring and Hibernate with little effort that is a great thing. When you can leverage those technologies with a Flex front-end, you get the best of both worlds.
