Enable server to send attachment via MTOM is very easy, just annotate the web service implementation class with javax. S The first wsdl request is omitted to save space. Client send request :. Enable client to send attachment via MTOM to server is required some extra efforts, see following example :. Thanks for this great example!

Comment 1. MTOM is designed for optimizing the electronic transmission of attachments. It must also use base64 encoding, where the binary data is present, and then embed it in the XML document, which will, in turn, increase the size of XML payload. An MTOM-enabled web services engine detects the presence of baseencoded binary data types.
Once the XML data is received at the receivers end, XOP package will de-serialize the infoset along with the extracted content and replace it in the XML where the corresponding external reference is present. Now drag and drop the following components from the palette in the same order onto the canvas:. Please note that it copied only the few portions of the response string.
In fact, it has 40, characters. If you look carefully, the data is part of the SOAP envelop message itself, no attachments are added. See the below picture:. We need to make some changes to the services to make use of MTOM.
There are many different implementation mechanisms to use MTOM. As mentioned earlier, now the SOAP message has just the reference s. This reference points to the MIME attachment. See the screenshots below. Integration Zone. Over a million developers have joined DZone. Let's be friends:. DZone 's Guide to.

Once these such operations are performed, the binary data can be converted to raw bytes for transmission. Now, it is time to get to the action. Create a new project viz. Create project in Anypoint Studio, by selecting the top menu bar. DataHandler; import javax. WebMethod; import javax. WebParam; import javax. IOException; import javax. FileDataSource; import javax.

Sending and receiving attachments with JAX WS and MTOM
By enabling MTOM, you can send and receive binary data optimally without incurring the cost of data encoding needed to embed the binary data in an XML document. MTOM optimization is not enabled by default. MTOM annotation on the endpoint. The MTOM annotation has two parameters, enabled and threshold.
JAX-WS attachment with MTOM
Processing of large incoming SOAP requests can be made more efficient with some additional effort. This allows you to read the SOAP message on-demand lazily, without needing to buffer the whole message in memory. MTOM and XOP allows you to send and receive binary attachments such as files and images efficiently and in an interoperable manner. Perhaps the best way to understand the pros and cons of MTOM is to see an actual on-the-wire message.
Enabling MTOM for JAX-WS web services
It provides an efficient mechanism for transmitting the binary data like Image,pdf etc between client and web service It uses XOP to serialize and deserialize the binary data in a more efficient way. On the other side, XOP package is deserialized to get the required binary data. In this way XOP packages the binary data in an efficient way. We have just created the web service interface and added a method for downloading the image. In this web service implementation class, we have provided the implementation for downloadImage method which takes imageName as a parameter and returns the image read from the specified path.
