Being built on OSGi can take you further

Luminis' Paul Bakker has just posted a screencast showing how GlassFish can be provisioned and deployed to Amazon's EC2 with the Apache ACE project.

In this demo Paul takes advantage of the OSGi nature of GlassFish to provision and deploy a Web Archive Bundle (WAB) using JAX-RS as one of the Java EE 6 features offered with the application server.


This page has all the details on OSGi Enterprise support including a link to the OSGi Application Development Guide.

The nice thing about open source is that people take the technology in unexpected/unplanned directions.

Amazon moves into PaaS with Elastic Beanstalk, Java as 1st class citizen


Amazon's EC2 and its sister S3 service have been indisputable leaders in IaaS for a long while now and GlassFish and more generally J2EE/JavaEE took advantage of it starting in 2008 (see here and here), with documented how-to's and significant production references.

Just yesterday, AWS's Evangelist Jeff Barr announced AWS Elastic Beanstalk (main page) which reads to me like Amazon's entry into the PaaS space (with Java!). This new service supports deployment of WAR-packaged Java applications to an infrastructure composed of a Container+Server (Tomcat on EC2) and a load-balancer with Auto Scaling and Notifications features. What seems less clear is the multi-tenancy story, if anything special is done for databases and JDBC connections but also whether containers can form a cluster to offer session high availability (HA).

It's great to see the Java platform as the primary (and for the time being only) target for such a service. Let's hope that support for the full Java EE 6 platform isn't too far out!

Exciting times ahead, the fun is only just starting, stay tuned!

Towards SailFin 2.0 - SIP Session Replication and HCF


SailFin is closing on v2.0 which is aligned with GlassFish v2.1.1 (both scheduled for the end of October, see Roadmap) and the team has been highlighting new features in the release:

• Prasad Announces HCF, provides an overview and a List of Fixes since SCF.
• Shreedhar writes about the Support for SSR (SIP Session Replication).
• Ramesh describes the Configuration Options, including DNS failover and Converged LB.
• Prateek Announces a new AMIs for SailFin based on OpenSolaris.

GlassFish Book Lists

Yesterday's post on the 2nd Edition of Antonio's book made me do a pass through different stores looking for GlassFish-related books.


A search in the main (US-centered) store showed too many (mis)hits so I created a ListMania list to search out the bad ones. There are 27 entries in the Books on GlassFish list. I still need to sort the items; some books mention GlassFish only very briefly while others are based on it.

Outside the US a plain search highlights the relevant entries: in French at, in German at, a plain Search at, and another Search in

Overall, significant progress in the last couple of years, accelerating in recent months. We tag relevant entries as Book.

Project WebSynergy on Amazon EC2 with OpenSolaris

Amazon Web Services

It's always nice to see others combining various technologies to come up with new and interesting applications. In this case, Natiku has described how to run Project WebSynergy onto the Amazon EC2 Computing Cloud. It runs the OpenSolaris OS. This could easily be farmed out to web startups who want to get a site up and running quickly for very low cost, while retaining the ability to pay more for more CPUs/bandwidth later.

Very cool, very cheap, and very easy!

OpenSolaris (and GlassFish and MySQL) on Amazon EC2


You may have seen Jonathan's note on OpenSolaris, MySQL and GlassFish being available on Amazon EC2.

Details on the OpenSolaris portion are available at the EC2 Blog (Welcome, Launch and New Limits), at Dileep's Blog and at the EC2@Sun and OS@EC2 sites. For MySQL check the MySQL@EC2 site.

I know that Homer worked on the GlassFish AIM AMI but it all happened right before JavaOne and I didn't have time to check more. He told me he is writing a note on it, and I'll spotlight it when it is ready.

And thanks to Charles for some of the Links.
