SOAP fault in SOA

A SOAP fault is an error in a SOAP (Simple Object Access Protocol) communication resulting from incorrect message format, header-processing problems, or incompatibility between applications.

When a SOAP fault occurs, a special message is generated that contains data indicating where the error originated and what caused it. This data is called a fault element. A message that includes a fault element is known as a fault message. A fault message can be generated by any node , and is transmitted to the first upstream node (the node immediately preceding it in the message path).

SOAP allows computer programs to communicate over a network even if they use different operating platforms. It employs the World Wide Web's HTTP (Hypertext Transfer Protocol)and XML (Extensible Markup Language) as the mechanisms for information exchange.

Difference between Route, Service Callout, Publish

When you are first starting with OSB it can be a little tricky to determine when to use a Route, Service Callout or a Publish node.  All three can be used to call either a Business service or a local Proxy service.  You can use the following lists to determine which will best fit your needs. Route Last node in request processing.  It can be thought of as a bridge between request pipeline processing and the response pipeline processing. You can only execute one route in your Proxy Service. Can only be created in a route node. OSB will wait for the Route call to finish before continuing to process. If you are calling a Business service  and  you specify  Best Effort  for QoS (Quality of Service), then OSB will release the thread it is holding while the business service executes. If you are calling a Business service  and  you specify  Exactly Once  or  At Least Once  for QoS, then OSB will hold onto the thread while the business service executes. If you are calling a l

OSB actions in proxy service

In this post we will see about different types of actions to message flows using the Oracle Service Bus Administration Console, such as route, publish, service callout, transport headers, conditional actions, error actions, and message transformation actions. Actions are the elements of pipeline stages, error handler stages, route nodes, and branch nodes that define how messages are to be defined as they flow through a pipeline            Action                           Description                     Dynamic Publish Publish a message to a service identified by an XQuery expression                          Publish Publish a message to a statically specified service.                        Publish Table Publish a message to zero or more statically specified services. Switch-style condition logic is used to determine at run time which services will be used for the publis
