com.volantis.xml.pipeline.sax.XMLProcessingException
Exception class used to indicate a Processing Error occured.
A Processing Error is generated if a problem is encountered by an XML XMLProcess which prevents it from generating any events. Recovery from a processing error requires that there is a process in the pipeline after the process which reported the error. The least that this process must do is to trap the error and not forward it onto the rest of the pipeline. @deprecated The distinction between a {@link XMLStreamingException} and an{@link XMLProcessingException} is irrelevant in terms of error recovery so{@link XMLPipelineException} should be used instead.


            // this process cannot execute with either of these two objects so
            // throw an exception if either one or both is missing
            if (request == null || response == null) {
                Locator locator = context.getCurrentLocator();
                XMLProcessingException xmlException =
                        new XMLProcessingException(
                                "Null request and response objects in context",
                                locator);
                fatalError(xmlException);
            }


            // Get valid a RequestDispatcher to dispatch to
            RequestDispatcher dispatcher = getRequestDispatcher(request);
            try {
                dispatcher.include(request, response);
            } catch (Exception e) {
                Locator locator = getPipelineContext().getCurrentLocator();
                XMLProcessingException xmlException =
                        new XMLProcessingException("Failed to include URI ",
