Global Education and Learning

Jedit, wordml, xaml, jxpath, InfoPath, XForms are some of the names that I have jotted down in 2003 to take a look at in the future. Hopefully I will get to some of these in 2004. The following knowledge folder named "Research" explores these ideas a bit further and provide additional references. Research Knowledge Folder On a personal front I want to consider the following: Provide a...

Java Communications

I've spent an inordinate amount of time debugging distributed protocol stacks and applications. Building distributed systems / protocol stacks is a tricky affair. It takes a lot of time and patience and testing to get it all right and then some. Reproducing bugs in such systems is tough. Building scalable test frameworks is tough. One normally resorts to looking at event logs and traces and the...

Portability or Interoperability – Can one helping the other? Portability is the ability to move a program or programing logic from one system to another system, usually with minimal overhead, or in the case of Java, virtually no overhead. Interoperability is the ability of systems to seamlessly communicate with each other. Where is the connection between Portability and Interoperability...

I recently started a project on java.net which allows untrusted users to upload classes to a SIP service platform (for customizing call control in a SIP network). In doing so I played around quite a bit with bytecode re-writing using the bcel library. I was quite surprised at the type of run-time customizations that this simple technique allows. Using this technique and by the simple expedient...

Java Desktop

My friend Max has a new 17" Powerbook so we spent the afternoon gathering the extra software he wanted to get up to fully productive speed. Among the downloads was NeoOffice/J v0.7.1, Patrick Luby's latest release of his Java-front-ended OpenOffice.org. The new version loads and runs way faster than the previous one and I'd really recommend it to Mac users as its compatibility with MS Office is...

I've been playing with Swing a lot lately for my new series of articles. In my research I came across another interesting class java.awt.Robot. It's a class that can automate the UI, mainly for testing. One particularly cool feature is the mouseMove function. Once I saw this I got evil ideas. :) Imagine rogue java programs that move the mouse cursor to mystify and befuddle the user. Spelling...

Well, Sun is releasing their so-called Java Desktop System this week. What, exactly, is the "Java Desktop System"? Plain and simple: it is Sun's Linux distribution focused on desktop users. Of course, Sun has too much invested in things like Solaris (which is losing market share since The Bust (and I'm not even going into the loss of mind share)) and Java for them to be clear in their...

Java Patterns

Exceptions is one area where opinions differ considerably. Not only about the usage of exceptions but also about the need and utility of checked exceptions. I hear arguments from various sides. They all seem valid in their own right. I use interfaces heavily in my coding practice. Particularly in my J2EE tool Aspire. Over time I paid dearly for not declaring exceptions on these interfaces....

First, take a look at the following URL. And if you are keen about the story behind it you can proceed to read the rest. Knowledge Folders of Satya Komatineni Like many other I-will-do-it-myself programmers I have ended up with my own blogging software at about the same time as the OSCON 2003. I had been planning on adding seemingly simple enhancements since then. Never gotten around to it. I...

Filters is an architectural concept that works hand in hand with factories. When factories create object or objects a filter provide an option to post-process these object or objects. This ability may not be as important in procedural and OO coding but place an important role in declarative programming. Because "declarative programming" when used as a supporting architecture for OO programming,...

As the story goes God devised multiple languages so that men can't build sturctures that span to the heavens. In our small world of programming architectures the men and women of the world are quite busy (with out much help from any Overseer) constructing a confusion of their own. The name of this confusion is called "Configuration". The larger and more complex an architecture is the simpler its...

Java Web Services and XML

[Another look back at the XML 2003 conference last week. I feel sortof blogspherically incorrect in waiting a week to write down these thoughts, but I wanted to let them bounce around a bit, and look at what others wrote.] Adam Bosworth of BEA delivered the opening keynote address on Wednesday. He started by reminding us of the dream that XML geeks shared back in 1998: Information should not...

The inaugural JXTA Bug Day has been fun. Met some new folks and chatted with vetrans alike. The best of all situations is when this *stuff* deploys, configures and renders in the "real world" relatively seemlessly ... and this has been a re-occuring comment from folks new to JXTA which happened upon JXTA Bug Day. Cool feedback has also been that it is great to have a JXTA reference...

Starting tomorrow, 2003.12.10, we will be using MyJXTA as a means to both test the newly minted JXTA 2.2 and collaborate on ideas, observations, etc via the JXTA Bug Day. All perpsectives are welcomed so if you have a JXTA itch to scratch this is a great opportunity. Feel free to try things out and offer observations, suggest improvements, sling some code, etc. Java == platform independence...

Java WebStart is amazing. It is just as simple as that. Installation is trivial and the opportunities to endless. I just combed the JNLP Specification and am impressed with the improvements contained within since I had last tooled around with JNLP. Enough WebStart gushing ... how am I using JNLP in my day-to-day. Here's the skinny. I have a rich client that sits on top of JXTA. We've been...

To me, the secret in building systems that rock, no, better yet, monster systems, is all in the *blend*. I don't buy the silver bullet, floor wax *and* dessert topping single focussed story lines that fashionably spill out from time to time inevitably resulting in misdirected project churn regardless as to the best of intentions. Such tactics are often enamoured deeply with one or another flavor...

NetBeans

NetBeans team announced some weeks ago the near future of NetBeans. Already last month it was possible to test the new window systems integrated in the trunk release. Very nice result. You can Drag & Drop windows, Tabulations, as you want. maximize the editor, change order of tabulation, ... see if the method is well an overriding method manage tasklist A lot of nice and very useful...

Today, like yesterday, I had the possibility to follow somes conference at Javapolis, organized by the Belgian Java User Group BEJUG. I missed the one concerning OptimalJ (based upon netBeans) of Compuware, because it was at the same moment of the conference concerning JSF, presented by Craig R. McClanahan. But At the end of this afternoon, I followed the conference given by Robert Brewin, the...
