Java Web Services and XML

So, I just attended Edge East 2004, a Web Services Conference here in scenic Boston. Full disclosure: I'm not exactly the world's biggest fan of the Web Services. My ten cents going in: they solve a very complex problem in a very complex way. And thus, they are to be feared. If you can, by any means, solve a simpler problem in a simpler way, you'll be happier. If you can, by any means, solve...

I know, I have never been really aggressive in any of my posts. The problem is that, even though there are some wise people - I am not wise, I am just reasonable - telling people they are doing bad things, they keep on doing it. I ought to speak out, then. I have no choice. I can't see people doing something so irrational and still remain silently. Sorry folks, if this entry offends you, but this...

[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...

JXTA

For a sizeable part of Jan '04 I was on the road. First stop, bondolo and I presented a "JXTA Tutorial" at the IEEE CCNC "Consumer Networking: Closing the Digital Divide" conference. The tricky part was condensing a two day tutorial down to a single four hour session. That work aside the day went by smoothly and was extremely interactive ... the type of class I like attending. Attendance was on...

The demos we intend to show next week at Linux World include: JackNet - devices We now have a cool "crystal ball" like lamp with swirling effects, etc. that we will control via JackNet. Upon pulling down the code I noticed that the "JackNet Clan" are aiming towards a x10 implementation ... should be fun. Go - JNLP link available ... no excuses The folks at Morgan Spenser Consulting...

Drop us a line if you are attending, or interested in attending, LinuxWorld and would like to "talk JXTA." Free exhibit passes are available up through Jan 19th.

Java Patterns

Introduction In this article I want to explain an architectural model that I use often called "parts and pipelines" using an example. This model is especially useful in declrative programming. This article will start by introducing an example where a web page will update some content on the server side. The quoted example will be analyzed to explain parts, pipelines, and declarative programming....

Introduction Nowadays "type" is an important programming language construct. A type gives a certain authenticity and a certain gurantee and a certain solidity to the programming practice, not to mention the metadata aspects of it while using IDEs. By the same token it binds you to that contract and could prove to be inflexible at times. In the web world things are fluid: hashtables, dictionaries...

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...

Java Desktop

Patrick Luby let me know that he's released v0.8 of NeoOffice/J, the Java-front-ended version of OpenOffice.org for Mac OS X. And that he's added Clipboard support! WoooHoo! Way to go Patrick! It's getting sooo close. [Also posted to Webmink]

I hear from my friend Neal that the webcast next Tuesday showing Java Desktop System should be good. Apparently Jonathan Schwartz and Peder Ulander will be showing several demos of JDS in action and also demoing the Looking Glass 3D desktop prototype (which Hideya continues to enhance - he's added a panning virtual desktop now as well and is exploring using the reverse of windows to display...

Microsoft is redefining the application interface around rich clients, and if Java does not have an answer, it faces being cut off from end users. The answer lies in matching Microsoft's richness while trumping it on security. FYI, I just published an article in Java Developers Journal: The Rich Client Strikes Back.

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...

Java Tools

How to style a simple block menu in HTML using CSS Recently I wanted to create a block menu in my html pages. I want this block menu to have a header indicating the category of the menu and a set of menu items. There may be more than one way of doing this exercise. There may also be a better way of doing the same. But here is how I have done it and it seem to work well for now. HTML menu code (...

Lomboz - a J2EE plug-in for Eclipse - has become open source. That is great news for the Eclipse and Open Source communities. A couple of days ago I was browsing the Web to get more information about JOnAS and JORAM. As both products are offered by the same entity (ObjectWeb), I decided to take a look at their repository. Then, once I clicked on that link, I got the suprise: it said Lomboz was...

As I have spent a good bit of the last 3 years in developing Aspire/J2EE, my discussions involuntarily drift towards floating this name. Foes ignore and friends, out of pure courtesy mainly I suspect, ask me what is Aspire/J2EE. I start, real fast (before they have a chance to retreat), and explain that it is a RAD tool for Java and J2EE ingeneral and you can do real cool things with it. And I...

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...
