my first web service implementation…wicket in action early access pdf-edition by manning

Hi,

I was given a web service implementation request to faciliate one specific order process and give it entry into the Web Service hemisphere. Well, learned from previous experiences from pervious employer I had itching feeling about the technologies that might help me to find solutions to the given problem given the limitation of not been able to use JEE specific implementations and the light web-container specific environment like apache tomcat and my lack of experience of implementing web services.  Fortunately, Myeclipse provides good tooling to utilize Xfire impelentation…so I take a look at the Xfire user guide and the job was done in no time….but also Matt Raible’s Appfuse specific web services section implemented in appfuse gave me good starting point. The Xfire is nowdays known also as Apache CFX..but given the JVM 1.4 limitaitons I could not implement the web service interface using annotations as in the simple CFX web service sample…so XFire specific quick start guide provieds the steps needed  to take in order to implement and test the web service WSDL file. I carried out the testing using SOAPUI- free testing tool for web services.

 

Other given task at hand is about implementing user interface using Apache Wicket framework - the Serverside article Introducing Apache Wicket by Nick Heudecker gives good head start…and good companion to that is also Mannings early access editon of Wicket in action…fortunately appfuse-light specific implemantation provides good code base to start impelenting your wicket project…other possibility is to create wicket quick start templete using maven2. Maven specific issues are explainde in guite in detail in Java World article Maven 2 POM demystified….and read also the follow-up article Get the most out of Maven 2 site generationor you could also use ant with maven ..to enable maven to take care of the jar depenencies and then to the excat beploy phase using ant maven tasks…as was done in appfuse-light implementaiton.  I faced still the diallemma of how to enable the usage of maven with Weblogic server 8.1…the problem was solved in an blog post- How to deploy Weblogic 8.1 Portal on Cargo Maven2. Those who use Weblogic server 9.x might find maven2 article Using Appc with Maven on Hussein Badakhchani’s Blog or using maven 2 to build bea weblogic portal applications …bood online maven book - nicly categorized .

Or in case you are not much fun of learing the maven internals–you could either use maven plugin with netbeans…it has wonderful integration with netbeans….as written in Maven is Magic in Netbeans in Gertjan blog

new enchancments to EJB 3 in the form of Singleton pattern

The article about the futher enhancments in EJB 3 specific spectrum by Reha Rahman highlits the new dimensions the EJB 3 specification is heading…added pattern of Singletons…you could send your feedback about the planned new features of EJB 3.1…give your feedback….also big influence in the whole was the Oracle’s Bea aqusition…the the Spring supporters are now one mammunt….read more about Rod Jhonsson’s feelings about this merge. Planning to attend some major Java seminars in Europe…why not to attend Java Sympohisum held In Prague during next Summer -

Attending Developing Bea Portal 9.2 course…web services in XFire way

Hi,

This week I have become familiar with the way Bea Portals are developed by attending a course - Bea Weblogic Portal 9: Developing Enterprise Portals. The course have given broad view how to utilize the broad set of services and tools provided by Bea Weblogic Portal. The ease of developing portals by using these tools is quite robust…but it takes a hands-on experience in some project before I could say that I would be proficient in developing the portals in first place. In addition, in order to expose Web Services in Spring…XFire is good choice for that purpose. Take a look at the streaming video sessions about XFire Web services hosted by Parleys.com site. Good way to become familiar with the concept of Web services is to read free publication from Java Blueprints - Designing Web Services with the J2EE 1.4 Platform: JAX-RPC, SOAP, and XML Technologies
