The IEP project system comes as a NetBeans
IDE 6.0 plug-in.
Handling Events
In the previous chapters of this book, we saw how to use the NetBeans Enterprise
Pack to build enterprise applications that can integrate with other systems. We saw
how developing systems, based upon receiving and sending messages, are defined
by a WSDL contract. In our approach so far, we have assumed that everything runs
as expected and that no errors occur. Of course, in the real world this is not the case
and so, our business processes defined by BPEL must take into account any errors
that may occur. This process is called fault handling. In this chapter, we will see what
support NetBeans offers to help us effectively manage fault handling within a BPEL
process. NetBeans Enterprise Pack provides support for several different types of
fault handlers and we will discuss each of them in this chapter.
In addition to fault handling, we will also take a look at event handling within a
BPEL process and see how NetBeans can help us in this area.
Within this chapter we will discuss:
Fault handling within WSDL documents
BPEL handlers
Fault handlers
Event handlers
Compensation handlers
Termination handlers
At the end of this chapter, you should have an understanding of the different types
of event handlers within a BPEL process and the support that NetBeans provides us
for managing these events.
