Teki-chan's Tech Key Chance

As this is the first post, Let's get it started with my previous articles posted in Builder.com:

• Building Web applications with JDK 1.4.2
  (21 Nov 2003)
• Easily present graphical data with JGraph (3 July 2003)
• Customize error logging with the Logging API (17 Jun 2003)
• JDK 1.4 lets you 'assert' yourself when you debug (9 May 2003)
• Test drive the regex package in JDK 1.4 (24 Mar 2003)
• Overcome security limitations to safely transfer files between applets
  (27 Feb 2003)
• Implementing client-side code for SSL in JDK 1.3 (22 Jan 2003)
• Gain SSL functionality in JDK 1.3 (14 Jan 2003)
• Take the new I/O in JDK 1.4 for a test drive (18 Dec 2002)

Because of my internal training, I was assigned by my boss to attend a
training called Introduction to Web Services. This training was
organized by IBM. This course was elementary, although I had developed
an application with Web Services integration three years ago by .NET.
It was still a good chance for me to know more about Web Services in
view of IBM and J2EE.

There was little evolution between three years ago and today, I felt.
Even the trainner said the biggest evolution was WS-Security. This is
right. Security was a big issue of Web Services because of its plain
text characteristics, although its success is also due to its open
format. I think this issue can be much improved if some critical
organizations such as banks and governments. If they promote this
technology, the public will be more confident to use this.

A trainee coming from the government said "we just want to know what it
is, but we do not want to implement it." This is the fact.

Because of the course limit, the trainner did not say in deep (most trainners do so) and just left us the following links:
