In the previous article (part 1 in WebSphere Journal vol: 3. iss: 4) we began
to build an SCA project in WebSphere Process Server. Here in part 2 we pick
up the discussion. To see the associated images, please view the article
online at www.ibm.com/developerWorks/websphere.
d. The business object is defined using standard XML schema type. You can
open the business object using an XML editor to see it. (You can open the
business object in a text editor by right clicking it and selecting Open with
=> and the editor of your choice.)
e. Save and close the Business Object Editor.
f. The XML schema should look something like the code in Listing 1.
3. We will now create a second business object to represent the response.
a. Create another business object following the same steps above. This
business object will have three fields:
customerId of type string creditScore of ty... (more)
My JSF article series and Meet the Experts appearance on IBM developerWorks
received a lot of feedback.
I would have to say, the most common question or feedback came along the
lines of comparing Struts to JSF. I thought it would be a good idea to
compare JSF to Struts by evaluating various features that an application
architect would look for in a Web application framework. This article will
compare specific features. Those on which I will focus include:
Maturity Controller Flexibility/Event Handling Navigation Page development
Certainly, there are othe... (more)
In this article, WebSphere consultant Roland Barcia answers questions on
developing J2EE and Web services applications on IBM Rational Application
Developer V6 and deploying and testing those applications on WebSphere
Application Server V6. Topics include using the various wizards,
perspectives, and tools in Rational Application Developer to develop
different types of J2EE applications, using the new Service Integration Bus
Messaging Platform in WebSphere Application Server V6, differences from V5 of
WebSphere Studio or WebSphere Application Server, using the default WebSphere
AJAX Requests – Data or Markup?
I just got back from the Real World AJAX seminar in NYC on Monday. Pretty
good event with lots of good stories.
One issue that caught my attention was the issue of how the back-end returned
the data to AJAX applications. Most of the speakers preferred data, except
for David Hansson from Ruby on Rails seemed to favor markup as the return
type (at least that is what I understood him to say).
This debate is pretty interesting. From an Enterprise Java standpoint, the
decision I believe has implications to the usage of the JSF, Struts, and
You may be thinking, oh great, not another programming model. What about Web
services? What happened to Enterprise JavaBeans? Well, Service Component
Architecture (SCA) is not meant to replace or compete with any existing
programming models. Instead, SCA gives you a model to define interfaces,
implementations, and references in a technology neutral way, letting you then
bind these elements to whichever technology specific implementations you
For example, we can define our interface in Java, and our implementation can
be applied as a BPEL process, or we can have my interf... (more)
