    Both XML-RPC and SOAP both support transporting binary data using base64-encoding. You can use Apache s XML-RPC implementation found here:

      Both XML-RPC and SOAP both support transporting binary data using

      You can use Apache's XML-RPC implementation found here:
      You'll be interested in the org.apache.xmlrpc.Base64 class.

      Apache's SOAP implementation can be found here:
      You'll be interested in the org.apache.axis.encoding.Base64 class.

      Additionally, the XML Schema encoding specifies two other binary
      data types:

      base64Binary (Base64-encoded binary data)
      hexBinary (hexadecimal-encoded binary data)

      Apache has a custom class for supporting the primitive XSD data type
      hexBinary called org.apache.axis.types.HexBinary.

      The Apache projects are open source so you can take out optional
      classes to meet the requirements of your embedded environment.

      SOAP with Attachments (SwA) is another option but you will have to
      use SwA APIs or the JavaMail APIs. The JavaMail APIs require the
      JavaBeans Activation Framework package so for both of those packages
      you are looking at about a 350 KB footprint.

      J2ME does not provide a SOAP implementation. However, there are a
      lot of open source SOAP implementations for Java that you could
      possibly port to J2ME, but to save you the headache there are
      already XML-RPC and SOAP implementation for J2ME from Enhydra.

      Enhydra has an XML-RPC API for J2ME found here:
      The org.kobjects.base64 package provides support for Base64 encoding
      of byte arrays.

      Enhydra has a SOAP API for J2ME called kSOAP which you can find
      here: http://ksoap.enhydra.org/index.html
      There is a Base64 (de)serializer class called

      kSOAP does not support SwA so if you really want SwA, you can
      combine kSOAP with JavaMail or some other mail attachment API
      available for J2ME. I heard Nextel has one but I can't seem to find
      it. There is a commercial product that offers it here:

      Transporting Binary Data in SOAP -
