Being an alumni of the school (many years ago ;), it was great seeing the new building of the
department, meeting the faculty and interacting with the students. I reached there an hour earlier so that I
can mingle with the staff and students and it was a lot of fun.
The department faculty proposed to use GlassFish instead of Tomcat for their
next semester assignment. I believe this is a great move as it will allow the
students to understand the simplicity and power of a great open-source
and Java EE 5 compliant Application server.
I initiated the process of recruiting a
Campus Ambassador from Delhi
University and this will help establish a better relationship between this
University and Sun Microsystems.
Here are the questions and answers that were asked during the session:
- Amongst the different Java training courses, how do I decide which one to pick ?
Sun Learning defines several
for different Java technologies (EE, SE, ME, Web Services and Web 2.0). Pick
an appropriate learning path depending upon your interest. In addition,
Sun Training Catalogue
(click on your country) shows different events conducted by Sun Learning in
the local geogrpahy.
- How does Sun make money with GlassFish being open sourced ?
That's true, GlassFish is 100% open-source and totally free to use. The
business model for Sun is that of selling support and services:
- What are the dis-advantages of GlassFish ?
GlassFish provides an open source, production-quality and Java EE 5
compatible application server. It has world class performance (,
.NET interoperable Web services stack, out-of-the-box clustering, load
balancing and high availability support. However instead of identifying dis-advantages,
here are some areas for improvement:
- Feature-wise: The footprint for GlassFish v2 is higher than some
non-full JavaEE containers (like Tomcat). This problem will disappear
GlassFish v3 which is small (< 100 kb), fast (starts up
< 1 sec) and modular (load only required containers).
- Community is not as well developed as Tomcat or JBoss because we
have not been around as long. However the
is continuously increasing.
- We are not yet as transparent as Tomcat, but we are more
transparent than anybody else (including JBoss). Transparency will
continue to improve in the future.
- Our governance is still in transition.
- Any comparison between NetBeans and Eclipse ?
Why NetBeans ?
explains the top reasons to use the NetBeans IDE. Some specific points are:
- Consistent UI across all platforms where as Eclipse runs best on
- A friendlier environment for people who are new with links to sample
apps and docs accessible from within the IDE.
- An easy to use website with tons of quality docs and screencasts.
Here are couple of more links that provide a comparison between the IDEs:
- What are the main features of Ruby as compared to Java ?
A comparison of Ruby and Java is explained in this
- Why Ruby when there are many other languages ?
- Ruby is getting popular due to
- Ruby-on-Rails very popular among web developers.
- JRuby is a pretty mature implementation of Ruby in Java, running on
JVM and able to use existing Java libraries.
- Complete deployment story on Solaris -- customer can chose native
RoR or JRuby on Rails on GlassFish.
- What is the difference between Tomcat and GlassFish ?
Tomcat is a Servlet container that can host JSP and Servlets. GlassFish is a
Java EE 5 compliant application
server that includes implementation for a Web services stack (Metro), EJBs,
Java Persistence and many others incuded in the
Java EE 5 specification.
In addition to this, GlassFish also provides out-of-the-box clustering, high
availability and load balancing capabilities that are required for
enterprise applications. Read more about

- What are the different ways GlassFish can be configured in NetBeans ?
- If you download a full version of NetBeans IDE then GlassFish comes
pre-bundled and is installed for you.
- You can configure an existing GlassFish installation on your machine
in the Services tab. If the Services tab is not visible, then select "
menu item and then "
Services". Right-click on "
Add Server...", select "
in the "
Choose Server" dialog box. Click on "
