LOTD #10: Running GlassFish on Joyent Accelerator

Joyent provides a cloud computing environment for all your needs.  

Beyond their typical reasons (scale on demand, pay for what you use, PHP/Rails/Python/Java pre-installed and ready to go, billions of page views and others), now there is another reason to use their cloud.

The instructions to configure GlassFish on Joyent cloud are really clean and simple. Check them out here!

Do you know that Rails applications can be deployed (without any packaging) on GlassFish v3 ? Check out more details here.

LOTD #9: Advantages of JRuby over MRI


Andreas blogged about why he likes JRuby even though he dislikes Java.

JRuby is "It's just Ruby" with more than 50,000 tests to ensure MRI compliance. The blog highlights that there is no need to know Java, at all, to run JRuby. Here are some advantages that are described in the blog:
  1. JVM runtime optimization
  2. Efficient memory usage
  3. Native threads to spread work on multiple cores
  4. Great garbage collection to make memory usage more efficient
  5. JIT and AOT compilation
  6. Inegration with Java libraries
  7. Running Rails applications on existing Java application servers
  8. Documentation and specs
Read more details here.

LOTD #6: Rails Deployment on GlassFish in 4 steps and 15 minutes

Charlie describes, in 4 easy steps, how to deploy any Rails application on GlassFish:



The main steps are:

Step 1: The App Server
Step 2: Package your App
Step 3: Deploy your application
Step 4: Tweaking (Optional)

And it should only take 15 minutes on GlassFish v2!

The conclusion of the blog is:

Hopefully this walkthrough clears up some confusion around JRuby on Rails deployment to an app server. It's really a simple process, despite the not-so-simple history surrounding Enterprise Application Servers, and GlassFish almost makes it fun :)

The next version, GlassFish v3, allows Rails application to be deployed natively, i.e. no packaging is required. You create a Rails application and run it - just the way you are used to! Read all about it here.

LOTD #5: Blogging Gold for Sun - Forrester loves it!

A recent report by Forrester Research published a list of 15 companies that really get corporate blogging and produce blogs that are informative, fascinating, and a joy to read even for people who aren’t die-hard fans of the company. Here is what the report says about Sun Microsystems:

Like Adobe, Sun allows their employees to blog. They’ve been doing it for a long time, and their blog portal has over 4,500 bloggers covering over 110,000 posts. Some of their blogs, such as that of Web 2.0 and Web Services Evangelist Arun Gupta, have become quite popular on their own. That’s 110,000 posts of promotional gold for Sun and they know it.

Here are recent statistics of blogs.sun.com:


That's a comment for each post! I'm happy that this blog contibutes it's share.

LOTD #4: Rails running on GlassFish @ LinkedIn


Light Engineering team (BumperSticker fame) at LinkedIn has chosen GlassFish for running their Rails application. One of the developers on the team reports:

Using Warbler, we successfully wrapped our Rails applications into WAR files and deployed on Glassfish (we’ll probably write a more detailed tutorial of this at a future date). A WAR file is completely self contained application that can be deployed simply by copying to an autodeploy directory. No more Apache/Nginx reverse proxy, no more Capistrano, no more installing gems on a production container, no more of any of that madness. This was a huge win, and we broke out the champagne bottles.

JDBC Connection Pooling for Rails on GlassFish

Stay tuned for more details!

NetBeans development and GlassFish deployment already provide an ideal environment for Rails deployment. You can read about successful deployments of Rails and GlassFish here.

LOTD #3: Rails 2.2 going multi-threaded


Rails 2.2 is slated to become multi-threaded. What does it mean for JRuby users ? Charles Nutter explains it:

Q/A: What Thread-Safe Rails Means

One of the key points from the blog is:

Rails deployments on JRuby will use 1/Nth the amount of memory they use now, where N is the number of thread-unsafe Rails instances currently required to handle concurrent requests. Even compared to green-threaded implementations running thread-safe Rails, it willl likely use 1/Mth the memory where M is the number of cores, since it can parallelize happily across cores with only "one" instance.

NetBeans development and GlassFish deployment already provide an ideal environment for Rails deployment.

LOTD #2: Phobos - MVC framework based on JavaScript

Phobos is a lightweight, scripting-friendly, web application environment running on the Java platform. It provides a complete MVC framework where Controller is a JavaScript class, View is an Embedded JavaScript (EJS) file and Model is typically a mix of Java and JavaScript.

The tech tip explains how Phobos and jMaki can be used to create a simple Ajax-enabled application using NetBeans tooling and GlassFish for deployment.
Another application built using Phobos and jMaki was shown in JavaOne 2007 technical keynote.

LOTD #1: Using Silverlight to access GlassFish Metro and JAX-WS Web service endpoints

Following TOTD (Tip Of The Day) pattern, I'm starting LOTD (Link Of The Day) series today. These are light-weight entries with generally a single line description and links to other blogs/articles/tips/whitepapers/screencasts/etc.

Let's start with three recent entries on MSDN that describe how to invoke Metro and JAX-WS Web service endpoints from Microsoft Silverlight and .NET:
