JBoss 5.x Tuning/Slimming
The following slimming recommendations are for a standard JBoss 5.1.0 GA “All” configuration. Slimming is very application specific, so this is by no means a universal document.
Google Wave Now Open For All
Google just announced the general launch of Google Wave at its annual developer conference in San Francisco. Until today, Wave was an invite-only service, but starting now, anybody with a Google account will be able to log into Wave and use it without any restrictions. Google will also enable Wave for Google Apps users today. In order to educate these new users, the Google Wave team has also created a number of new videos and case studies that highlight how organizations can use Wave to collaborate more effectively.
Google Code Blog: OrangeScape makes Google App Engine ready for business applications
This post is part of the Who’s @ Google I/O, a series of blog posts that give a closer look at developers who’ll be speaking or demoing at Google I/O. This guest post is written by Mani Doraisamy from OrangeScape who will be demoing as part of the Developer Sandbox.
Google App Engine took two bold steps in the right direction for cloud computing in making its datastore distributed to ensure scalability and durability and in fixing its architecture to be stateless to ensure failover and availability. To quote Henry Ford: “Any customer can have any application that is scalable so long as he builds for this fixed architecture.”
To date, it has worked very well with the social web app companies, but the enterprise application development community has mostly stayed away from Google App Engine for three reasons:
- “Newness” to Google App Engine’s concepts of GQL, lack of aggregate queries, denormalized schema.
- Lack of transaction support: commit or rollback on distributed storage and read consistency within transaction scope.
- Relying only on the cloud: not being able to run the same application on standard infrastructure inside your company.
Now you can build business applications on Google App Engine, too! OrangeScape is a Platform-as-a-Service for building business applications that run both on the cloud via Google App Engine and in your data center.
It has three main benefits:
- It provides a modeling environment to build business processes and rules, datamodel using a familiar process design and spreadsheet like interface. The application that you build on this interface can be deployed on Google App Engine in a single click.
- It enhances the persistence layer of Google App Engine to support transactions and read consistency on BigTable. It makes it so transparent that there is absolutely no difference for you to build applications on BigTable or on relational databases.
- If you are a solution provider building business applications today, you may not know if all your customers will accept running applications on the cloud. Some might expect that applications run on their data center. With OrangeScape, you can build it once and run it on both – cloud and data center.
If you are excited to try it out, bookmark http://trial.orangescape.com/. We will making the public beta announcement shortly after Google I/O.
Google Code Blog: Google Storage for Developers: A Preview
As developers and businesses move to the cloud, there’s a growing demand for core services such as storage that power cloud applications. Today we are introducing Google Storage for Developers, a RESTful cloud service built on Google’s storage and networking infrastructure.
Using this RESTful API, developers can easily connect their applications to fast, reliable storage replicated across several US data centers. The service offers multiple authentication methods, SSL support and convenient access controls for sharing with individuals and groups. It is highly scalable – supporting read-after-write data consistency, objects of hundreds of gigabytes in size per request, and a domain-scoped namespace. In addition, developers can manage their storage from a web-based interface and use GSUtil, an open-source command-line tool and library.
We are introducing Google Storage for Developers to a limited number of developers at this time. During the preview, each developer will receive up to 100GB of data storage and 300GB monthly bandwidth at no charge. To learn more and sign up for the waiting list, please visit our website.
We’ll be demoing the service at Google I/O in our session and in the Developer Sandbox. We’re looking forward to meeting those of you who are attending.

XMPP service – Google App Engine
With the introduction of the XMPP service to App Engine, it’s now possible to write an App Engine app that communicates with users – or even other applications – over XMPP, otherwise known as Jabber or Google Talk. In this article, we’re going to walk through an example that covers all the basic functionality of the XMPP API.
