  • 7 Application Deployment Best Practices  (May 20, 2012)
    Someone just asked me to define ?best practices? for a collection of application deployments. The question was impossible to answer because the applications we were talking about were all bespoke, so each one had good and bad ways of deploying them. It would take an age to go through each one and explain which is the best way of doing their unique installation operations. Preview......   (read more)

  • Understanding How OSGI Bundles Get Resolved: Part I  (May 20, 2012)
    I?d like to review how OSGI bundles get resolved and use Apache Karaf to demonstrate. Karaf is a full-featured OSGI container based on the Apache Felix kernel and is the corner stone for the Apache ServiceMix integration container. For part one, I will discuss how bundles are resolved by an OSGI framework. In part two, I?ll demonstrate each rule using Apache Karaf. Let?s get started. ......   (read more)

  • Creating a Custom Spring 3 XML Namespace   (May 20, 2012)
    For me historically maybe the least approachable part of the Spring Framework is the system to define custom XML schemas to use in the configuration files for defining beans (The ones like aop, security, integration , util, etc).

  • NIO.2 I/O Operations on Asynchronous Channels Are Not Atomic   (May 20, 2012)
    This part of my NIO.2 series wasn't on schedule when I started writing about NIO.2 aasynchronous file channels. It deals with an important detail: read and write operations are not atomic. What that means is that AsynchronousFileChannel -> write() does not garantee to write all bytes passed as parameter to the destination file. Instead it returns the number of bytes written as return......   (read more)

  • Computer Algorithms: Karatsuba Fast Multiplication  (May 20, 2012)
    Typically multiplying two n-digit numbers require n2 multiplications. That is actually how we, humans, multiply numbers. Let?s take a look of an example in case we?ve to multiply two 2-digit numbers. Preview Text:  Typically multiplying two n-digit numbers require n2 multiplications.

  • Access WSO2 Registry Programatically  (May 20, 2012)
    When you have many services it is a good thing to register them somewhere so your consumers can easily find them, see what they are about, determine whether the service levels are good enough etc. When you look back at the heyday of SOA everyone was pusing registries (or repositories, but that terminology is a different subject). To fully do SOA you needed a UDDI registry to accompany your......   (read more)

  • Apache Camel Tutorial - Introduction to EIP, Routes, Components, Testing and other Concepts  (May 17, 2012)
    Data exchanges between companies increase a lot. The number of applications, which must be integrated increases, too. The interfaces use different technologies, protocols and data formats. Nevertheless, the integration of these applications shall be modeled in a standardized way, realized efficiently and supported by automatic tests. Such a standard exists with the Enterprise Integration Patterns (EIP) [1], which have become the industry standard for describing, documenting and implementing...   (read more)

  • Tracing Solaris Hosted Java Application without Changing Source Code?  (May 14, 2012)
    There are many good tracing tools for Java, for example, jvisualvm, which is included in the JDK release, is very handy and provides rich capabilities. Still, most of these tools lack the combination of extreme dynamism, nonintrusiveness, and broad capabilities of the DTrace framework....   (read more)

  • A Funny Thing Happened on Java?s Way to the Cloud  (May 17, 2012)
    On the surface, everything seems fine. If you do a search, you?ll see lots of people offering support for cloud-centric application frameworks. But, when I speak with companies actually moving Java applications into the Cloud or trying to create new Cloud services based on Java, I get a different story. It?s not the application in many cases that?s in the way, it?s the JVM. An example that highlights these issues comes from one of our partners, Intalio. Intalio offers Cloud solutions based...   (read more)

  • Java Jury Deliberating Google?s Patent Infringement  (May 16, 2012)
    Oracle?s Java patent infringement case against Google and Android went to the jury Tuesday afternoon. The jury, which delivered only a partial verdict on copyright infringement last week, deciding that Google infringed but unable to say whether that infringement made ?fair use? of the IP, is now down to 11 jurors. One juror reportedly called in from the San Francisco Bay Bridge with car trouble, unlikely to make court at all. The judge excused her from ever coming back, ZDnet said, and pushed...   (read more)

  • DSLs with Groovy for Beginners  (May 16, 2012)
    I've been neglecting my blog, but just a quick note to mention that my latest talk at JavaOne, DSLs with Groovy, is posted up on Slideshare.

I'm hoping (but not promising) to turn the talk into a series of Blog entries in the coming weeks.  So if you want, just wait, and I'll send you explanations in more digestible bits and pieces in the coming...   (read more)

  • Judge Finds Google Copied More Java Code than Jury Said  (May 15, 2012)
    District Court Judge William Alsup, who refused last week to decide whether Google had fairly used the Java IP a jury said Android infringed, had no trouble Friday deciding that the jury made a mistake in finding Google only copied nine lines of Java?s rangeCheck code as well as infringing the sequence, structure and organization of 37 Java APIs. In a judgment as a matter of law the good judge said Google directly copied eight other Java files and that it wasn?t a petty little thing. FOSS...   (read more)

  • Do Software Patents Stifle Innovation?  (May 12, 2012)
    Of late patents around mobile technologies have been in the news. Four high profile news items are (1) Oracle suing Google for Java patent violation, (2) Apple and Samsung fighting each other in different parts of the world, Microsoft, Apple, Rim and others jointly buying Nortel patent library for $4.5 billion and (4) Google buys Motorola Mobile and gets 17,000 patents. This is only the tip of the iceberg. This diagram from Reuters shows the complex battlefield of mobile patent and significant...   (read more)

  • Google Demands New Java API Trial  (May 10, 2012)
    Google, as expected, has put in its papers asking the court to declare a mistrial because the jury only decided it infringed 37 Java APIs in building Android and didn?t decide whether that infringement constituted so-called ?fair use? of the code. So it wants a whole new trial ?as to both infringement and fair use as to Oracle?s claim that Google is liable for infringement of its copyright on the structure, sequence, and organization of the 37 API packages.? Google claims the two issues ?...   (read more)

  • Functional thinking: Functional design patterns, Part 3  (May 14, 2012)
    The Gang of Four's Interpreter design pattern encourages extending a language by building a new language from it. Most functional languages let you extend the language in a variety of ways, such as operator overloading and pattern matching. Although Java doesn't permit any of these techniques, next-generation JVM languages do, with varying implementation details. In this article, Neal Ford investigates how Groovy, Scala, and Clojure realize the intent of the Interpreter design...   (read more)

  • Necessity is the mother of invention...  (Jul 17, 2011)
    While working in eclipse, I've often found myself with 20+ java, xml, wsdl, xsd, etc. editors open at one time. Finding the desired editor can get unwieldy so I FINALLY created a plugin to give me greater control over the open editors in the eclipse environment. I hope the java/eclipse community finds it as useful as I have.To be sure, there are other eclipse plugins out there that help out with this, but not to the extent that this plugin does. I think it provides a few extra levels of...   (read more)
