Intro to Oracle SOA Suite for GFESB Users

So, Oracle we are then.

If you are interested in trying out the Oracle SOA Suite from the perspective of someone who is familiar with GlassFish ESB, then attached are several documents which will get you started....

Creating Dynamic EJB Proxies to JAX-WS External WebServices using the Dispatch API

As a follow up to the last blog entry, how can we handle a similar situation for JAX-WS webservices where we need to change the value of the endpoint dynamically at runtime ? Using the Dispatch API again....[Read More]

Creating Dynamic EJB Proxies to JAX-RPC External WebServices using the Dynamic Invocation Interface (DII)

As a follow up to the last blog entry, how can we handle a situation where we do not have access to the WSDL at runtime or we need to change the value of the endpoint dynamically at runtime.

Well for JAX-RPC webservices we can use the Dynamic Invocation Interface (DII).....

Creating EJB Proxies to External WebServices Using the Dispatch API

Whilst JavaCAPS6, and specifically the HTTP Binding Component, have many useful features, there are currently limitations with it, notably calling JAX-RPC webservices using soap encoded arrays and calling webservices using SOAP1.2.

With JAX-WS you get access to the Dispatch API which makes it easy to call both of these use-cases from Java code.

Wrapping the Dispatch code inside an EJB, exposed as a doc/literal webservice, is a simple way to create a proxy to these external webservices, this EJB-WS can then be called from BPEL, for example, via the JavaEE SE making the overall process very efficient.

BPEL2.0 SE - Transactionality - Persistence and Atomicity

It is important to understand with the BPEL2.0 SE how the "atomic" flag and persistence affects transactionality.

See my entry on the JavaCAPS Grok which is equally applicable to OpenESB to understand when the combinations of atomicity and persistence should be used.

JavaCAPS6 / OpenESB Architectural Best Practices

As always with any new product, Architectural Best Practices are a must.

JavaCAPS6 provides the user with significant new features in terms of performance improvements, transactionality, scalability etc... but more than this, many more choices on how to architect solutions.

I've created a collaborative collection of pages on the JavaCAPS Grok outlining some of the architectural options and best practices using JavaCAPS6, some of which are equally appropraite for OpenESB.

There's a wish list on there as well, if you'd like to see something, add it to this or leave a comment on this blog and I can add it.

Creating Re-usable Business Services Using EJBs

JavaCAPS 6 / OpenESB offers a very flexible toolset when designing SOA projects. Reusable services can be created in BPEL 2.0, XSLT and EJBs.

A very powerful feature of JavaCAPS6 / OpenESB is the "late-wiring" possibilities that the Composite Application Service Assembly editor (CASA) offers, you can design reusable services and wire them up to multiple external systems using CASA, meaning your service is not just bound to a particular external system, for example.....

There are many tutorials and examples of how to do just this with BPEL and XSLT but little information on how to do this with EJBs.

The tutorial is attached below and is also available on http://wikis.sun.com/display/JavaCAPS/Grok+Java+CAPS where you will find many other useful tutorials and references for JavaCAPS6 in particular
