In this chapter, you l earned the capabilities of SOA Suite to enable unit testing. You learned how to define a unit test with an initiating message, emulation of an external reference, and adding both successful and failed assertions. You learned how to execute the unit test in the EM console.

[ 332 ]. Download at WoweBook.Com Adding Exception Handling The goal of every good programmer is to write unbreakable software programs. The extent to which this goal is achieved largely depends on how well one is able to handle and manage expected as well as unexpected exception conditions. Object-oriented languages such as C++ and Java provide an efficient way for handling exceptions using constructs such as try, catch, and finally.

With service-oriented applications, most of what is available at the language level is still valid and usable, but raises different challenges once you start orchestrating services and creating composite applications.. Introducing exception handling With service-oriented applications, the need for strong exception handling is even more important as the quality of service becomes a critical factor in service reusability. Inadequate or faulty exception handling can severely impact the usability of a service. How exceptions are handled depends on the type of exceptions that can possibly occur.

Exceptions that occur in a service-oriented composite application can be broadly classified into two categories System Faults and Business Faults.. Download at WoweBook.Com Adding Exception Handling The terms Exception an jar PDF417 d Fault tend to be used interchangeably. For example, the BPEL specification uses the term Fault, whereas Java uses the term Exception for anticipated and unexpected errors that occur during the execution. Oracle SOA Suite 11g uses the term Fault for exceptions occurring during execution of a composite.

. System faults System faults are gene jvm PDF 417 rally thrown by the underlying infrastructure when a runtime, system-level error occurs. For example, if a service being invoked is not reachable either because of network issues or due to unavailability of the service provider, the SOA infrastructure will throw a connection exception. Given the nature of these exceptions, you can generalize exception handling across all components as well as composite applications.

For example, you may create a single exception handler that notifies system administrators about service unavailability for all connection-related errors.. Business faults Business faults are th j2se PDF-417 2d barcode rown when an exception condition occurs during processing of a service operation, in the business logic of the service. This exception condition may be due to the violation of certain business rules, to invalid data, or to other non-system related conditions. Generally, business exceptions are handled specifically by the invoker of the service and not as generic exceptions as is done for system faults.

. Exception handling in Oracle SOA Suite 11g For example, BPEL prov jboss pdf417 2d barcode ides constructs as a part of the specification for catching and handling exceptions, whereas the Mediator doesn"t. Using the constructs available in BPEL, one can define exception handlers for handling all types of exceptions. BPEL supports two levels of granularity when it comes to attaching exception handlers Scope-level and Process-level.

BPEL also defines, as part of the specification, a list of runtime exceptions. runtimeFault and bindingFault are some examples of BPEL runtime exceptions..

Oracle SOA Suite 11g p rovides comprehensive exception handling and management features. Some are component specific and some are more general and available at the infrastructure level..
