DEBA for web services benefits from the decoupled nature of web services and the asynchronous nature of the Observer pattern.

The interaction between the target objects and the visitor can be implemented using DEBA.

The DEBA framework is an implementation of this unique capability.

There is a great deal of flexibility in the DEBA framework to handle exceptions.

Now let's look at some code to see how it all works.

It is the Observer pattern on top of the base web services infrastructure that gives DEBA its callback capability.

We've implemented a framework for DEBA for web services as set of Java classes.

In Figure 7, we combine some of the models already presented, illustrating DEBA's flexibility.

Follow the links in Resources below to download the DEBA framework code and the sample code that accompanies this article.

Thus, DEBA provides a truly dynamic workflow model that is highly decoupled and does not need to be described in advance.

DEBA is characterized by distributed active components waiting for events.

Using the DEBA framework, developers extend AbstractWebObservable to implement their own observable web services on top of the framework.

So the DEBA architecture is naturally complementary to Grid computing.

All messages in DEBA are request-response operations.

You can implement the Strategy pattern using DEBA for web services.

There are two layers of proxies in the DEBA framework: SOAP proxies and the framework's own, all packaged in deba. core.

Named said the reason is also quite backing: Deba is McDull the students, it would only naive cats, and the owner of the pet is a cat;

It can also serve as a basis from which you can implement your own DEBA framework applications. The classes in the example application are
