JBI advocates that XML data based on a WSDL model should be flowing through the NMR. Hence, a reference to an appropriate SOAP framework capable of understanding WSDL and generating WSDL-compliant formatted data is important in any JBI discussion.

ServiceMix has the best integration with XFire, which is the new generation Java SOAP framework. Since the API is easy to use and supports standards, XFire makes SOA development much easier and straightforward. It is also highly performance oriented, since it is built on a low memory StAX (Streaming API for XML) model. Currently, XFire is available in version 2.0 under the name CXF. In this chapter, we will not discuss any JBI specific binding methods; instead we will concentrate on XFire and look at how we can use the same for integration solutions.

Once we appreciate this, we will better understand what part of the integration functionality can be done using XFire within the JBI architecture.

We will cover the...
