• RESTful error handling with Tomcat and SpringMVC 3.x

    Updated: 2011-02-28 21:43:00
    Handling errors in a REST way is seemingly simple enough: upon requesting a resource, when an error occurs, a proper status code and a body that contains a parseable message and using the content-type of the request should be returned. The default error pages in Tomcat are ugly. Not only they expose too much of [...]

  • JavaFX 2.0 Roadmap

    Updated: 2011-02-28 07:27:17
    In case folks did not notice the JavaFX Script Language has been converted to pure Java APIs for JavaFX 2.0. I’ve recently been fortunate to be able to take things out for a spin (JavaFX 2.0 EA). To my surprise I am very impressed by the work of the JavaFX teams and the amount that had been done so far. James Sugrue

  • JMS Performance Comparison

    Updated: 2011-02-24 22:42:00
    This white paper from Fiorano presents a performance analysis of publish/subscribe and PTP messaging throughput of the following JMS Servers: FioranoMQ® 9.1.1, SonicMQ 7.6, Tibco EMS 4.4.0, ActiveMQ 5.3.0, Jboss Messaging 1.4.4, Sun JAVA MQ 4.3, IBM WebSphere MQ 7.0 All comparisons are performed using the independent benchmark test harness and tests released by Progress Software, Inc. The tests include a number of scenarios for both Publish/Subscribe (Topics) and Point to Point (Queue) message scenarios, stressing out the JMS Servers in a variety of simulated real-world scenarios. These JMS tests and test harness have been the international standard for JMS testing since 2003. read more

  • Java SE 7 Preview Build

    Updated: 2011-02-23 22:36:36
    >Oracle has made a developer preview release of Java SE 7 (formerly JDK 7) available for use. Not only is this the first time I've seen Oracle refer to JDK 7 as Java SE 7, they're asking for all Java developers to beat on it and report any bugs before it becomes finalized. The final release is planned for July, and with JavaFX 2.0 moving along as scheduled, I hope to see it bundled in there (at least optionally) as well. Read more about Java SE 7 (including a link to download the pre-release) here: http://blogs.oracle.com/java/2011/02/java_se_7_developer_preview_release_now_available.html Happy coding! -EJB

  • Terracotta Adds Search to Ehcache

    Updated: 2011-02-17 04:35:42
    Terracotta had added native high-performance search to Ehcache, the open source de facto cache for enterprise Java, making it possible to do simple queries and real-time analysis on terabytes of in-memory data, overcoming in the process the latency of making queries to comparatively far distant databases. Leveraging in-memory data stores in support of both transactional and analytical applications is supposed to make real-time query and analysis development costs cheaper because they both use the same native object level APIs. It could also save on hardware like Oracle’s Exadata machines.read more

  • Oracle Nominates User Group to Replace Apache on Java EC

    Updated: 2011-02-03 12:00:00
    Oracle has proposed replacing the Apache Software Foundation with SouJava, the Brazilian Java User Group, on the Java SE/EE Community Process (JCP) Executive Committee (EC). The big 20,000-strong user group would be represented by Bruno Souza. There is no other user group on the committee, never has been. Even the usually contrary Simon Phipps, Sun’s former open source advocate, who enjoys throwing brickbats at Oracle from off-stage, couldn’t find anything bad to say about the nomination, blogging that Bruno and SouJava may be able “to use their new position of influence to fix the broken things (like the opaque decision-making and the ability to have FOSS-hostile licensing terms on JSRs).”read more
