Examples of java.io.ByteArrayOutputStream

java.io.ByteArrayOutputStream
ByteArrayOutputStream is a class whose underlying stream is represented by a byte array. As bytes are written to this stream, the local byte array may be expanded to hold more bytes. @see ByteArrayInputStream

        // if a WSDL was found
        if (wsdlElement != null) {
            OMNamespace wsdlNamespace = wsdlElement.getNamespace();


            // serialize and create an input stream to read WSDL
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            try {
                if (trace()) trace.info("Serializing wsdlElement found to build an Axis2 service");
                wsdlElement.serialize(baos);
                wsdlInputStream = new ByteArrayInputStream(baos.toByteArray());
            } catch (XMLStreamException e) {
