Resin application server - Java EE 6 Web Profile Certified

May 2014 News

Resin 4.0.40
 
Happy May! It has been a busy past few months for the Caucho team with exciting new developments. We are on the brink of a cool new open source project release as well as developing Resin 5 (more below). Check out our updated web site that features a better interactive look and feel. If you’ve had a chance to play around on the site, let us know how we did!

The current release is the most stable release of Resin to date and is a maintenance release. We fixed the following bugs:
 
-Resin Administration cross site scripting
-Resin remote deployment
-Quercus: We continue to improve the stability of Quercus as it is a useful tool for those looking to combine PHP and Java

Resin 4.0.40 is now available for download at http://caucho.com/download

 
Resin 5 – Faster and Lightweight
 

Resin 5 is currently under development with a roadmap release of early Q3 2014. With this version we are focusing in on the performance components of Resin including websocket optimizations, our asynchronous servlet implementation, incorporating HTTP 2.0, and Java EE spec updates. Resin’s new packaging will be inline with the anti-fragile and agile wave of technologies.

Resin 5 will feature an even smaller file size as we strip out our jms, ejb, jsf, jca, jcache, apache, and iis implementations. The reason behind this is twofold: it allows us to focus on the architecture vital to performance and reliability and also reduces the possibility of bugs within our codebase. Of course, Resin is pluggable and will still support these technologies (jms, ejb, jsf, jcache) if you need them.

Core Resin 5 development is focused around:

-Clustering revamp
-Deploying revamp
-Configuration revamp
-CDI, EL, other EE specs
-Proxy load balancer
-Http cache
-DB revamp

 …and more!
 

Looking to update your current or legacy architecture to a simple and more efficient model?

Resin 4 offers many advanced features and exceptional performance in a lightweight container. Users migrating from WebLogic or Websphere to Resin will initially find the workflow associated with development and administration differs greatly between the two products. However Resin users tend to find configuration and development to be very natural and efficient, especially compared with other application servers.
 
Architecture migration is slow and cumbersome. However, it is a necessary for highly competitive companies that want the ability to utilize the latest technologies within their product. Whether you are looking to cut back the expensive costs of licensing or want to begin moving your application to a more resource conscious environment, we have a detailed wiki guide that will get you started:
 
 
Who Should Migrate:
 

Current Application Status Action Next steps
Application developed on Resin or Tomcat, deployed to WLS or WAS Migrate to Resin Resin is used in production for highly demanding and heavy load sites. Migrating production deployment to Resin is fast and familiar to developers.
Application uses Servlets, JSPs, or frameworks like Spring, Struts, or Wicket Migrate to Resin Resin is known for its fast Servlet and JSP implementations that offer lightweight, low complexity, yet enterprise-ready stability and reliability
Next generation of the application will use JavaEE 6 Web Profile technologies like CDI or EJB 3.1 Lite Migrate to Resin Resin is a Java EE 6 Web Profile licensee and has high quality early access implementations of CDI (Resin CanDI) and EJB 3.1 Lite that are fully integrated into the application server.
Application uses clustered sessions for improved reliability Migrate to Resin Resin's Clustering implementation offers high reliability, easy configuration, and dynamic clustering for both internal and external cloud deployments
Application integrates or runs side-by-side with PHP applications Migrate to Resin with Quercus Resin include Quercus, Caucho Technology's reimplementation of PHP, written in Java. With Quercus, PHP applications can integrate and/or run side-by-side with Java application in the same container, often with vastly improved performance.
Application testing environment uses an embedded server such as Jetty or Tomcat Migrate to Resin Resin offers a sophisticated embedded test environment that allows not only HTTP request-style testing, but also unit testing for EJB and CDI components.

 
 
 
JDK 7 Certification
 

We are months away from passing Java 7 certification. Resin supports many of the new features in Java 7, including websocket.  Since Caucho was an early implementer of websocket, we are providing a code change for the final Java 7 TCK’s.

Development of Resin 4 has been finalized and we will continue to fix bugs. Our efforts are now focused on Resin 5 and our newest project Baratine http://www.baratine.io, a GPL in-memory service platform.

Java Users Group

We had a packed house for our April Java Users Group as John Clingan from Oracle presented what’s new in Java 8. He covered topics including Lambdas, Functional Interfaces, Type Interfaces, Streams, Java Profiles, and more. He presented cool demos to show what these code implementations look like.
 
The May JUG was a lively “Hands-on workshop for Better Unit Testing” presented by Llewellyn Falco (in Google Glass). We all look at unit testing in a different light. 
 
Caucho engineers Nam Nguyen and Sean Wiley to present the June San Diego JUG
 
Baratine offers unprecedented support for building distributed in-memory resource services and is a culmination of over 16 years of industry experience all packed into a 7MB file size. By allowing your resources to own their own data within the same JVM, Baratine presents a truly object orientated approach to building resource services without developers needing to worry about cache coherency, database migration schema, and performance. Don’t miss out!

New Community Support


 

Resin Google Group

Due to an influx of spam on our forums and improvements made surrounding Google groups, we have moved the community support for Resin to:
 
https://groups.google.com/forum/#!forum/caucho-resin
 
One common question seems to be surrounding the Resin Pro licensing. Resin Pro licensing is available on a yearly or enterprise basis. The optimized features within Resin Pro will function when a valid license is present. Upon expiration, Resin Pro automatically reverts to it’s GPL state. This means that to continue using and benefiting from the performance and administration that Resin Pro provides you will need to keep your license up to date.
 
If you have any questions about what we’re up to or are coming to San Diego in the future, feel free to contact us at sales@caucho.com or (858) 456-0300 and drop by office to say hello and talk code.

Caucho Newsletter – January 2014

Resin application server - Java EE 6 Web Profile Certified

January 2014 News

Resin 4.0.38
 
We hope everyone is off to a great beginning in 2014! With the start of the New Year we thought it would be beneficial to begin an in-depth review of Resin’s architectural stack. For Part 1, we will dive into the world’s fastest web server that, if you aren’t already, should be taking advantage of! Resin is meant for data-rich and intensive enterprise web applications. As such, the internal components are coded to provide the extra performance and insight needed to give your applications a true edge.
 
General feature updates and bug fixes in 4.0.38:

  • Resin Cluster – Dynamic server improvements to aid in the automatic restart after a triad server has been restarted
  • Resin Cache – Configuration added to maintain minimum thresholds in cloud environments
  • Resin Health – Thread pool analysis from PDF reports now available in new formatting

Visit http://caucho.com/resin-4.0/changes/changes.xtp for a complete list of bug fixes and improvements in this release.
 
Download Resin 4.0.38

 
Resin Essentials (Part 1) – Resin Web Server
 
Resin is engineered to work from end to end with specific thread optimizations made at each level of the architecture. Often is the case that applications will include components chosen by familiarity rather than performance. If your application includes an Apache Web Server, your architecture will handle 40-150% more load with fewer errors by utilizing Resin’s Web Server. If your application includes an NginX server, your architecture will handle 20%-25% more load with fewer errors by utilizing Resin’s Web Server.  In deployment you not only pay this fine in dollars spent on hardware and resources, but also on time managing multiple configuration files. Resin’s Web Server is yet another finely crafted component in an architecture that simply works.
 
Resin Web Server functionality:

  • Powerful and Easy to configure URL rewrite rules
  • Added security and functionality through Virtual Hosting
  • FastCGI so you can work with Python (Django), Ruby (RoR), native PHP, and more
  • Built-in HTTP Proxy Cache so you can speed dynamic pages to near-static speeds
  • Built-in mod_php like support via Quercus
  • Cluster aware load balancer that auto shares loads to new application server nodes
  • Security: Immune to buffer overflow attacks that plague other Web Severs (mostly Java with small, tight, fast JNI/C)  

Resin’s Web Server can make the difference in your application’s ability to seamlessly scale from one to millions of concurrent sessions. As an added benefit, the load balancing and clustering ensure that your application optimizes its resources redundantly across your stack.
 
Scott Ferguson, Chief Architect of Caucho said the following:
 
“For years Resin has not needed Apache httpd as a load balancer or to serve static HTML files and images. With Resin you get a complete web solution. Resin pieces are designed to work together, and designed to be fast and scalable. Performance is easy to demonstrate with our web tier, and it is the same type of performance you can expect throughout our product for session replication, proxy cache, object cache, and more. Using Resin means you value craftsmanship, and are a discerning, informed developer.”

San Diego Java User's Group – January 21

This months San Diego Java User’s Group focused on “Simple and Fun Functional Programming in Java” by Allan Schougaard. It was a very interactive JUG, with audience members debating different code segments and best practices (exactly the kind we want!). On the basis of maintainability, readability, and abstraction we’re sure participants left the meeting with some code refactoring of their own to do!  
 
Abstract: Functional programming is all the rage right now, and for good reason. It promises simpler and faster programs. Some of the holdbacks are that many people believe that it requires you to change programming language. Not so! In this talk I will show that you can use functional programming techniques and reap many benefits in the current incarnation of the Java language.
 
Check out the slide deck on the SDJUG’s site!
 
Please join us at the next JUG scheduled Feb 18, 2014 for a great night!

Moving to the Cloud?
 
As cloud environments continue to mature, more companies are benefiting from migrating towards newer infrastructure. Flexibility, increased collaboration, and disaster recovery are among the top reasons fueling the movement. However, concerns about sensitive user data and having to rearchitect legacy apps mean in house systems will not be going away anytime soon. Whether a public, private, or hybrid environment is right for you, Resin is architected to work in all environments. For those wanting to port certain applications to the cloud, check out our cookbook on how to deploy Java apps on Amazon EC2:

Tip of the Month


 

Enabling Resin Web Administration

Since the resin-admin is just a web-app implemented with Quercus/PHP, enabling it is just adding an appropriate <web-app> tag.
 
To enable the /resin-admin, you'll need to create an admin user and password.

  1. Create an admin user following the prompt at /resin-admin.
  2. Copy the conf/admin-users.xml.generated to conf/admin-users.xml.
  3. Change the resin_admin_external to true if you need access from a non-local IP address.
  4. Browse /resin-admin with an HTML 5 browser. 

The steps are for security reasons. Copying the admin-users.xml verifies that you have access to the server. And the default resin_admin_external=false makes sure you're not exposing the /resin-admin to the internet.
 
A detailed walkthrough can be found here!

Quercus Corner


As the PHP adoption rate continues to grow, we continue to make improvements to Quercus.  The Agile movement has led to more client-side scripting and Quercus continues to bridge the gap to the server side Java components. Quercus highlights: 

  • Meets or exceeds the performance of the C PHP implementation with common PHP applications
  • Optimized compilation of PHP to Java
  • Single process model of Java reduces unnecessary switching overhead
  • Shared data allows for caching across multiple requests
  • Java implementation eliminates many traditional security problems such as buffer overflows
  • Input/output filtering for cross site-scripting and other attacks is simple with Java EE
  • Natural, high performance integration of Java libraries in PHP applications
  • Allows Java developers to use PHP as a front-end technology
