New Releases, Partnerships and Success Stories!

“Resin Pro has the advantages of being lightweight and fast. Thanks to the fast and precise support of Xest Information Technology, Caucho’s Korean partner, we have been able to create our current Resin operating environment. I've used WebLogic, Jeus, JBoss and other app servers. Resin is the most satisfying of all of them.”

These changes are being implemented at the request of developers. Send us your bugs at http://bugs.caucho.com/main_page.php

Case Study – Korea's largest media company increases performance by 30% and reduces TCO by 40% by migrating from WebLogic to Resin

Check out these impressive performance and cost savings results for ChosunILBO, Korea’s largest media company that also publishes the most influential newspaper in the country.

“Before Caucho, we used WebLogic in our main business systems. By migrating to Resin, we 'caught two birds with one stone’ and successfully achieved high performance. We also reduced our total cost of ownership (TCO) by 40%.”

- SeongHyun, Song, Sir. Development Team, ChosunILBO

Working with our Korean partners, Xest Information Technology, ChosunILBO replaced WebLogic with Resin. Engineers benefitted from the following changes in productivity, performance and scalability:

They could increase work efficiency rapidly by a simple setting method and configuration change
They could apply app source changes without downtime even if application source code was altered frequently
By using Resin’s lightweight and rapid restart in less than 10 seconds, they could minimize downtime and increase efficiency by over 30%

Because Resin provides seamless integration with popular frameworks including Spring, iBatis and Struts, developers used Resin as the core for their vital applications while successfully integrating their legacy applications.

The Intramart Figtree Innovation Centre will seek to develop upon the existing product IP offered by NTT DATA Figtree Systems, NTT DATA Intramart and Caucho to provide a mutually beneficial sales model and growth strategy throughout the over 5,500 existing clients, distribution channels and NTT DATA Group companies.

Caucho is honored to join the Intramart Figtree Innovation Centre. We look forward to working with our friends in Australia!

Cool Resin Tip: Dispatch Rules

Controlling flow, access, and authorization within individual web-apps is simple with Resin.

Resin's dispatching is based on a list of dispatch rules configured in the resin-web.xml or the resin.xml configuration files. Each rule has a regular expression matching request URLs. The first dispatch rule that matches takes control of the request. For example, a <resin:Redirect> sends a HTTP redirect, and a <resin:Dispatch> dispatches the request as normal.

Each matching rule can rewrite the URL using a target attribute that accepts Java regular expressions. The following rule flips the first two segments around, so /foo/bar would become /bar/foo.

Basic conditions check the request and return true if the condition matches. Conditions can check on authentication (<resin:IfUserInRole>), the remote IP (<resin:IfNetwork>), check for SSL (<resin:IfSecure>), and check for activation time (<resin:IfCron>) or if a file exists (<resin:IfFileExists>).

The rewrite conditions can also be used as security conditions, e.g. for <resin:Allow> or <resin:Deny>.An action tag can have zero condition tags or at most one. If you want combine multiple conditions, then you'll need to use composite conditions like <resin:And>, <resin:Or>, <resin:Not>, <resin:NotAnd>, and <resin:NotOr>.

Example: send 403 Forbidden if port is 80 and user is not admin

<web-app xmlns="http://caucho.com/ns/resin"
xmlns:resin="urn:java:com.caucho.resin">

<resin:Forbiddenregexp="^/secret">
<resin:And>
<resin:IfLocalPort value="80"/>
<resin:Not>
<resin:IfUserInRole role="admin"/>
</resin:Not>
</resin:And>
</resin:Forbidden>

</web-app>
