Today I needed to test a bunch of code which is given here

The article talks about using Dojo and JSON for AJAX applications.

There is a sample application available on the site for the article.Its a zip file when extracted

has the following structure.

• web
• actions
  example1.jsp
  example2.jsp
  example3.jsp
  index.jsp
  js
  WEB-INF
  welcome.jsp.html
  
• java
• README.txt
• build.xml

Now i need to build a WAR ( Web Archive ) for deployment on my container - Tomcat.

I would like to highlight how to establish a connection between MySQL a database and your JAVA app.

I assume you have installed MySQL and Java .

You must download the Mysql Connector/J 3.1 from mysql.com .

I downloaded the file mysql-connector-java-3.1.13.tar.gz and used the file

mysql-connector-java-3.1.13-bin.jar

Now in the Java class where want to connect to the MySQL database , addthe following code
[code lang="java"]

Class.forName(”com.mysql.jdbc.Driver”) ;

Connection Con = DriverManager.getConnection(”jdbc:mysql://localhost:3306/

database_name”,”user”,”pass”);

[/code]

Now you can use the Con object to carry out the queries.

Day 1 was pretty much a surprise..

i had to take a bus ride to a venue which i had never seen before.. i took my id

card and notebook and left home early having no idea what the conference

would be like.Registrations were between 7 and 9 .. i reached there at abt 8. i

got my id card scanned and got the itenary and stuff.. There was supposed to

be a Concert in the evening.. ( Drum Maestro Sivamani and Ghatam Maestro Vikku Vinayakaram along with Mandolin Rajesh )

We had our morning coffee and biscuits and then moved on to the show .

We took our seats in the main audi and we were shown some videos and ppts on Java and Sun.

Matt Thompson spoke for a while and then the show was taken over by Kiran Karnik of NASSCOMM and Laura Merling of SD Forum.

Then we did not have the so called break.. Then i moved to

Track2 :Java EE and Web 2.0 Programming using the Blueprints .

Here i got to meet the speaker Mr. Sridhar Reddy,Technology Evanagelist .. We did some chit chat on AJAX and I promised him to attend the AJAX session later in the day

Then came Java and .NET interoperability using Web Services.

Lunch followed this

after lunch came the keynote by Laurie Tolson & Karen.

Tegan Padir.

After this i went to the wrong track Persistence Techniques for Java SE and Javaâ???¢ EE Applications using EJB 3.0. I have no idea what EJB is, so it found some sleep in this session .. he he ..

Next was

Web-tier Programming Codecamp I : Java Server Faces .

Java Server Faces is a very new trend in Web Server Programming. The power

of Sun studio creator in creating Java Server Faces was shown. It was a very

cool session ..The next session was

Web-tier Programming Codecamp II : AJAX.

AJAX is a relatively new technlogy being used too widely these days .. i have worked on small AJAX projects… So was very interested in the name and technology.. I grabbed my seat in he front rows for this session as the speaker seemed to interest me a lot.

The speaker elaborately explained AJAX in and out using Adaptive Paths whitepaper on AJAX…

I was so engrossed in the discussions that i forgot about the concert that was at 7 pm…I was talking to all AJAX savvy people in the crowd who had thronged the speaker with questions..

Suddenly i realised tat it was time for the concert and rushed towards it …

On the way i had to give the survey form to get my Sun Tech Days Strolley

bag…wow .. i was right in time for the concert … i got to stand near the dias

… Man i almost went deaf.. The music was so loud and fast.. Everyone enjoyed

it for sure. People enjoyed the concert much more than anything on that day

The concert went on for about 1 hour upto 8 approx… After the concert it was

time to catch the bus back home.. and get back here for another set of

sessions tomorrow .. What a great day it was… I am dead tired.

Thanks to Balakumar .M for most of the photos

I had been to Sun Tech Days for 3 days. The event was held in Chennai trade Centre ,N
Nandambakkam.

The conference was held for 3 days on 7th ,8th and 9th of this month.

The 3rd day was a bonus day called “Netbeans” and “Solaris Day”

Netbeans is the IDE from Sun for development and Solaris is their OS powering their Servers like Ultra SPARC.

Sun has also open sourced a version of solaris and called it Open Solaris.

Lets get on with my story.

It was the first time i was attending a conference of this magnitude. The sponsors of the conference were Sun , AMD, Oracle, Forum Nokia, SAP etc…

The event was being managed by Sercon. It was a great job done by them.

The turnout was more than expected.. About 3000 people supposedly.. Most of them - developers in chennai software concerns. A huge bunch of the attendees were Part time developers and students like me .

The food was managed by ITC park sheraton. Long queues but they were handled perfectly.

A decent crowd also ..so no mishaps..
