webservice返回base64Binary的字符串
axis自动生成的客户端使用DataHandler接收如何获取内容?
正常应该是返回给我的base64加密字符串，我现在获取出来的都是乱码

源码
org.apache.axiom.util.stax.XMLStreamReaderUtils.getDataHandlerFromElement(reader)

难道是因为使用了Base64DecodingOutputStreamWriter导致的？



   public static DataHandler getDataHandlerFromElement(XMLStreamReader reader)

        throws XMLStreamException

    {

        WritableBlob blob;

        Writer out;

        int event = reader.next();

        if(event == 2)

            return new DataHandler(new EmptyDataSource("application/octet-stream"));

        if(event != 4)

            throw new XMLStreamException("Expected a CHARACTER event");

        DataHandlerReader dhr = getDataHandlerReader(reader);

        if(dhr != null && dhr.isBinary())

        {

            DataHandler dh = dhr.getDataHandler();

            reader.next();

            return dh;

        }

        blob = new MemoryBlob();

        out = new Base64DecodingOutputStreamWriter(blob.getOutputStream());

        break MISSING_BLOCK_LABEL_101;

        ex;

        throw new XMLStreamException("Error during base64 decoding", ex);

        writeTextTo(reader, out);

        IOException ex;

label0:

        do

            switch(reader.next())

            {

            case 4: // '\004'

                writeTextTo(reader, out);

                break;



            default:

                throw new XMLStreamException("Expected a CHARACTER event");



            case 2: // '\002'

                out.close();

                break label0;

            }

        while(true);

        return new DataHandler(new BlobDataSource(blob, "application/octet-string"));

    }
