This approach is the simplest way and is only suitable for transferring a small amount of binary data. The following picture depicts this process: Upon receiving the SOAP message, the receiver decodes the encoded String in order to re-construct the original binary data. In other words, the raw binary data is converted to an encoded String which is value of an XML element in the SOAP message. In the approach employed by this article, the binary data is embedded directly in the SOAP envelop using base64 text encoding. Understand how to transfer binary data via web services The web services library to be used is JAX-WS ( Java API for XML Web Services) which is a built-in technology in Java EE family and is also available in Java SE 6 or later. content of an arbitrary file) using base64 encoding/decoding approach. The getEncoder() method returns the Base64.Encoder class instance that encodes using the Basic type Base64 encoding scheme.In this tutorial, we are going to provide an example of a web services-based application that transfers binary data (e.g. ![]() The basic encoder keeps the things simple - no line feeds are added to the output and the output is mapped to a set of characters in the Base64 Alphabet ( a-zA-Z0-9+/). The simplest way to Base64 encode a string in Java is by using the basic encoding scheme. Let us start with the basic encoding example. Now it is time to do the actual Base64 encoding in Java by using the Base64 class. The decoder ignores all line separators or other characters not found in the base64 Alphabet. Every line, except the last line, is separated from the next line by using a carriage return \r followed by a linefeed \n. ![]() The encoded output is represented in lines of no more than 76 characters each.
