Baratine News

Baratine 0.10 Released 

Asynchronous reactive applications (See are the future of web applications. However, the large base of developers building asynchronous distributed applications has not yet come to fruition. We believe that this is due to the sheer complexity needed to build and maintain these solutions. Toolkits and frameworks currently require very low level message handling and force developers into a programming model that is not natural to the object oriented style of Java.
Baratine is a platform for building a network of loosely-couple POJO microservices. In this way, Baratine can be thought of as a “high-level” abstraction for reactive programming. Within Baratine, the only requirement of developers is to implement the methods from the API they design. This is in stark contrast to models that enforce an “extends” statement in base level classes and opens up the understanding of an application from just a few expert engineers, to an entire team of engineers now able to create enterprise quality distributed applications.
Baratine is moving Java forward with the next stage of encapsulation. Currently we are updating our documentation to illustrate how many models can be implemented within Baratine. The list currently stands at: 

  1. Hello world
  2. Batching
  3. In-memory
  4. Sharded
  5. Id generation
  6. Multi-pod
  7. Pub-sub
  8. Workers/integration with legacy
  9. Map-reduce
  10. Store
  11. BFS
  12. Database bardb
  13. Mysql/mongodb
  14. Child services
  15. Compute
  16. Facade APIs
  17. Vertx integration

If you have any questions about Baratine and current use cases please reach out to us at:!forum/baratine-io or drop us a line at (Don’t worry Baratine is Open Source and free to use!)

Resin News

Resin 4.0.45 on

Along with working on the technology to fuel the next generation of web apps, we continue to improve our long-standing cloud platform in Resin. The lastest version of Resin, 4.0.45, is now available for download. It includes bug fixes and increases Resin's stronghold as the top tier web and application server. Please report any bugs you come acoress to If you’re looking to expedite a bug fix, a short demo reproducting the issue always helps us out.

One other item to note is that we will be back porting the new Resin 5 database into Resin 4. Our new model will provide even better stability when corruptions occur and should be out in 2-3 weeks.

Greetings! Let's get you up to speed with what has been going on at Caucho!

Baratine News

Baratine 0.9 Release 

We pride ourselves on being able to identify and provide the latest implementation technology for web applications. Considering the sheer number of devices that can now access web apps, the landscape for building these applications is constantly evolving. In order to respond to the growing number of connections, more emphasis is being placed on the asynchronous ability of new apps and this is also a major focus for us.
Currently we are working on what we see as the de facto standard for building fully asynchronous, scalable, and independent SOA services in Baratine. We see this technology as the dominant driver of what new applications will need and much of our time has been devoted to building this platform. The upcoming Baratine 0.9 release moves us very close to production ready. You can find more news about Baratine on or below in the Baratine section.


Baratine Projects

Two early projects we are working on as proof of concepts for the Baratine platform are:
• Baratine + Lucene – For indexing and searching files stored in the Baratine Distributed File System
• Bartwis – A Baratine clone of a Twitter-toy clone written in PHP & Redis
These two projects are close to reaching their final stage and can be explored currently on the baratine github ( We are very excited to see how the community will expand on these applications within the Baratine environment.
The Lucene + Baratine plugin illustrates Baratine’s ability to take a previously written library, that was designed as a fully blocking and locking service, and with just a few lines of Baratine coding, transform it into a fully asynchronous service.
The Bartwis project highlights Baratine’s flexibility and performance. We have fully implemented Redis in Baratine to show the magnitude of Baratine’s capabilities. In this example, Baratine transforms simple POJO classes into fully redundant services under the hood, so users are able to use this application to achieve Redis-like functionality with no restrictions on what data structures are supported. In fact, if developers found a particular data structure more efficient than what is available in Redis today, they could simply implement that structure as a Baratine service and receive the microservice and asynchronous capabilities of Baratine automatically.
Of course this is just the beginning, head over to our github and take a look at the projects for yourself today!

Resin News

Along with working on the technology to fuel the next generation of web apps, we have continued to improve our long-standing cloud platform in Resin. We are encouraged to see new deployments in the areas of mobile and desktop alike benefiting from Resin’s stable environment as customer’s utilize it in hosted environments as well as on premise at their own sites. We have continued to fix bug requests (see below). If you’re seeing odd behavior in your application, please file a bug at

• jsee: self signed cert should support Firefox and Chrome default cipher-suites(#5884)
• jsee: self signed cert should check expire (#5885)
• class-loader: excessive reread of jar certificates (#5850, rep by konfetov)
• log: add sanity check for log rollover (#5845, rep by Keith F.)

• session: orphan deletion throttling needs faster retry time (rep by Thomas Rogan)
• mod_caucho: slow PUT/POST uploads with Apache 2.4 (#5846, rep by Stegard)

Resin v3 to v4 Migration

Earlier this year we held an Advanced Resin 4 training session going over the many aspects of Resin that can be utilized for high availability, resilient recovery, and post mortem analysis. Quite a few deployments are still utilizing Resin 3. While Resin 3 is a great platform, we’d like to encourage our users to move to the better performing Resin 4 platform.
Resin 4 has significant features including cloud support, application health visibility, and unprecedented high availability.
Understandably, there might be current technologies in your application stack that are preventing you from upgrading. Resin 3 support will be sunset in January 2016, we’d like to offer an upgrade path for our current users. If you are currently running Resin 3 and would like a review of your application stack to gauge what would be necessary in an upgrade, contact  Our developers will work with you to mitigate any potential conflicts with your current stack and also help layout similar configurations to get you up and running on Resin v.4 in no time!

Resin 5 is currently in alpha as we continue to implement the Servlet 3.1 (4.0 when available), HTTP 2.0, and WebSocket specs.

Resin 4 Tip

REST config for Nagios

Looking to setup remote monitoring software with your Resin installation?
The /resin-admin directory, contains an index page with a “rest” example toward the bottom. You can customize this rest page to get the information about your application that you are interested in.
Equivalently, by browsing to the /php/admin/WEB-INF/php/*.rest pages, you can get an example of how JMX values can be extracted from Resin in simple PHP pages. These can then return the result in a format for one of the standard monitoring software plugins such as Nagios.

San Diego Java Users Group

Our last meeting of the year was a great presentation by Brian Sletten entitled Doing REST “Right”. Brian has been speaking on REST for the past 9 years and his presentation focused on how a properly decoupled REST system should function and the benefits it would withhold. 

After two years of hosting the San Diego Java Users Group we are passing the torch to ResMed for the new location of SDJUG meetings.

Baratine News

Baratine: 0.8.7 In Progress!

With technologies such as Docker, Mesos, Finagle, and etc., becoming more prevalent in enterprise architectures, Microservices have become more than just another buzz word. Baratine’s premise to lower what is needed in terms of lines of code as well as complexity will undoubtedly push us towards a truly agile and reactive age of infrastructure. Why deal with complex multi-tiered caching when you can have a fully redundant, writable file system, capable of speaking any protocol over REST, Websocket, or HTTP and is capable of sharding and sharing its data to multiple clients asynchronously? Of course, that is just a slice of what Baratine is capable of doing and we are excited to continue pushing forward on this project.

The latest Baratine release will feature a simplified deployment structure allowing for multiple jar deployments to a single pod as well as simplified configuration. Head over to to download and get started with it today!

Also, we are currently answering questions on our Google Groups forum at:!forum/baratine-io
