Things are slowing down for the holidays.

Here’s are my picks for this week:

From a recent JavaWorld article:

“New business divisions focused on Application Platform Software and Cloud Computing and Developer Technologies demonstrate renewed commitment to software, with open source products like Glassfish, MySQL, and NetBeans at the fore.”

Currently I’m working on refactoring the Camel router to two BPELs example to add a BPEL front-end.  (I’ll be updating this post soon with links to the tutorial steps and screen captures.)

Previously I created/tested separate Composite Application projects for testing the database and file processes.

Then I created/tested a Composite Application project for testing the Camel router using the above processes.

What I’ve now done is create a new Composite Application project reusing the Camel and BPEL projects.   In the next tutorial I show how to create a “front-end” BPEL process to invoke the Camel router in this new application.

Working on the Open ESB Camel SE, developing a more real world content-based-routing example, the new example now provides some logging.

By using the multiple String argument form of to (Fluent Builders Java DSL) I was able to have some POJOs get control before and after a message was sent to a target BPEL process.

PORouter3/PORouter/PORouterCamelJBIModule/src:
org/camelse/examples/porouter/AppRouteBuilder.java

  // Routes based on expression evaluation
  //(POJOs write messages to log)
  from(jbiInURI).
    choice().
      when(orderPriceGT500).
        to("bean:LogPOJO1", jbiBpel2DbURI,"bean:LogPOJO1").
     otherwise().
        to("bean:LogPOJO2", jbiBpel2FileURI,"bean:LogPOJO2");

Each POJO logs the message with the POJO’s name (so I can see which route was taken).  This is a slightly different approach to Apache Camel’s wire-tap EIP.

The order in which the messages appear within the log (and the timestamps) distinguish before from after for each POJO.

The early Open ESB Camel SE examples use a simple input message with an Apache Camel Enterprise Integration Patterns (EIPs) content-based-routing XPath expression.

I needed to work on a more realistic example involving messages with namespace qualified elements, so I updated the routing logic to pass a Map of namespaces to the XPathBuilder before configuring Fluent Builders Java DSL content-based-routing.

  // Sets up a namespace-qualified XPath expression
  XPathBuilder orderPriceGT500 =
    new XPathBuilder("//po:OrderInfo/po:OrderPrice > 500");
  Map nsm = new HashMap();
  nsm.put("po", "http://www.globalcompany.com/ns/order");
  orderPriceGT500.setNamespaces(nsm);

and:

  // Routes based on expression evaluation
  from(jbiInURI).choice().when(orderPriceGT500).to(jbiBpel2DbURI).
    otherwise().to(jbiBpel2FileURI);

From this week’s edition of the Netbeans Weekly Newsletter,

here are a couple of highlights:

1. Under Calendar:
   • Celebrate Software Freedom Day with NetBeans! (September 20)

Under Projects:

• Project OpenESB to Graduate to Open Source with Commercial Support

“Project OpenESB is an Open Source project that is building an ESB that consists of both a runtime and a design time tooling based completely on NetBeans. In the last few years, OpenESB has made important contributions to the NetBeans IDE, for example, the WSDL editor, the CASA editor, the BPEL editor, and more. GlassFish ESB, the first milestone of a commercially supported binary distribution, is now available. The distribution includes NetBeans and adds extra components, such as JAXB based code seeding, a JCA wizard, and more, that are not available in the IDE’s standard downloads.”
