Method Detail

process

public void process()
             throws ProcessingException

Description copied from interface: IProcessingComponent

Performs the processing required to fulfill the request. This method is called once per request.

Specified by:

process in interface IProcessingComponent

Overrides:

process in class ProcessingComponentBase

Throws:

ProcessingException - when processing failed. If thrown, the IProcessingComponent.afterProcessing() method will be called and the component will be ready to accept further requests or to be disposed of. Finally, the exception will be rethrown from the controller method that caused the component to perform processing.
