JavaOne 2006 - Day1

I am attending JavaOne 2006 at Mascon Center, San Frascisco,CA. Today is my first day. This conference will end on May,20,2006. This is my first conference. It is very nice experience. I came here on Saturday night and register myself on Monday,15, May,2006.

Day1, Tuesday morning at 8.30 the session started with general sessions by Java CEO and other leading technical people.
Sun is planning to release Java to OpenSource. The question was asked like this. Wheather Sun plans to release Java to OpenSource and it was answered that it is not WHEATHER, but HOW. That shows Java is going to be available to OpenSource. Still they need to work out the existing licence and compatability issues. Thanks Java.

General sessions insisted everyone to join JCP.org and Java.net. Motorola CEO predicts mobile applications will be taking the ride in coming 10 years using Java. Linux Unbuntu and Java are availble in desktop in China and South Africa.

Motorola device won Duke's best Music device award.

Marc Fleury, CEO of JBoss was not willing to talk about JBoss and Redhat merge, but he informs that they are not decided about the name. Either name can be REDBOSS or JHAT!!!

Some of the annouements on Day1

Java EE 5.0 is available to production.

JMS goes to OpenSource.

Project Tango was renamed WSIT and that goes to OpenSource.

BPEL engine moved into OPENESB.

All OpenSource products will be named under Open Java EE.

After the general sessions, attended EJB 3.0 session. It is very nice and gave nice details about EJB feature.

Second session was Essential Lessons for Distributed Caching. It was from Tagosol CEO. It is very nice and in detail.

Third session was Concurrent collection utilities in Java SE 5.0.

Fourth session, TestNG which is alternate to JUnit

Fifth session is Portlet 2.0 with JSR 286. With JSR 286, it looks like we will have event for portlets and render parameter for portlet.

I left at 6.30pm to my hotel.

Spring Components - XML configuration on steroids

The single most important feature in Spring 2.0 (IMO) is a new XML
configuration convenience feature. I believe this is going to
revolutionize the way people develop for Spring and bootstrap a modest
component market too. This is a lot more than a convenience features
- it’s a fledgling component model too.

LdapTemplate: LDAP Programming in Java Made Simple

The Java Naming and Directory Interface (JNDI) is for LDAP programming what Java Database Connectivity (JDBC) is for SQL programming. There are several similarities between JDBC and JNDI/LDAP (Java LDAP). Despite being two completely different APIs with different pros and cons, they share a number of less flattering characteristics:

* They require extensive plumbing code, even to perform the simplest of tasks.
* All resources need to be correctly closed, no matter what happens.
* Exception handling is difficult.

The above points often lead to massive code duplication in common usages of the APIs. As we all know, code duplication is one of the worst code smells. All in all, it boils down to this: JDBC and LDAP programming in Java are both incredibly dull and repetitive.
