Examples of org.apache.axis2.transport.MessageFormatter

org.apache.axis2.transport.MessageFormatter

MessageFormatter implementations are used by Axis2 to support serialization of messages to different message formats. (Eg: JSON). Users can register MessageFormatter implementations against a message type using the axis2.xml. Message type for a message can be specified by setting the "messageType" property in the MessageContext. This can also be given as a parameter in the service.xml/axis2.xml for a per service based/engine wide configuration.

            } catch (AxisFault axisFault) {
                throw new JMSException("Unable to get the message formatter to use");
            }


            String contentType = messageFormatter.getContentType(
                msgContext, format, msgContext.getSoapAction());


            boolean useBytesMessage =
                msgType != null && JMSConstants.JMS_BYTE_MESSAGE.equals(msgType) ||
                    contentType.indexOf(HTTPConstants.HEADER_ACCEPT_MULTIPART_RELATED) > -1;
