    problem serialize byte[] property as base64Binary

    Manfred Möbus Newbie

      Have set up web service in JBoss 4.0.2 of type document/literal,
      the argument of my method is a user defined type which contains a field of type byte[].

      class DataDTO() {
       public byte[] data;

      the wsdl (generated with wscompile as recommended) contains the schema for this and looks as follows:
      <complexType name="DataDTO">
       <element name="data" type="base64Binary" nillable="true" />

      To my understanding this should define that the byte array is converted to a base64 encoded string on the wire, and converted back on receiving side. I have no custom serializers or other stuff.

      When this DataDTO structure is used as return value, JBoss returns on the wire
      i.e. for every single byte a data tag is transmitted. This is then not understood by a .NET client set up after the generated wsdl.

      On the contrary when .NET invokes such web service and has a DataDTO as argument, it correctly sends

      but JBoss evidently insists on something like it has sent, therefore thinks that AQIDBAU= is the decimal reprecentation of a single byte in the data array and encounters a NumberFormatException, with following stack trace:

      Did I make something wrong here,
      or is byte[] not correctly supported in this circumstances?
