Subject [jira] Created: (AXIS2-755) base64Binary is not encoded
Date Sat, 20 May 2006 11:41:29 GMT
base64Binary is not encoded
---------------------------

         Key: AXIS2-755
         URL: http://issues.apache.org/jira/browse/AXIS2-755
     Project: Apache Axis 2.0 (Axis2)
        Type: Bug

  Components: databinding  
    Versions: 1.0    
    Reporter: Kent Tong


In my WSDL (as attached), I have a message element of type base64Binary like:

			<xsd:element name="uploadRequest">
				<xsd:complexType>
					<xsd:sequence>
						<xsd:element name="id" type="xsd:string" />
						<xsd:element name="file" type="xsd:base64Binary">
						</xsd:element>
					</xsd:sequence>
				</xsd:complexType>
			</xsd:element>

When the client sends a file to the service, what the service gets is the base64 encoded representation
of the bytes, not the bytes themselves:

	public void upload(com.foo.schema.UploadRequest req) throws IOException {
		InputStream in = req.getFile().getDataSource().getInputStream(); //this is the encoded string,
not bytes
		...
 	}

In the generated UploadRequest.java, the factory's parse() method is like:

		if (reader.isStartElement() && new javax.xml.namespace.QName("", "file").equals(reader.getName()))
{
			java.lang.String content = getElementTextProperly(reader);
			object.setFile(org.apache.axis2.databinding.utils.ConverterUtil.convertTobase64Binary(content));
			...
		}

The convertTobase64Binary() should decode the string, but it doesn't:

    public static javax.activation.DataHandler convertTobase64Binary(String s) throws Exception{
        // reusing the byteArrayDataSource from the Axiom classes
        ByteArrayDataSource byteArrayDataSource = new ByteArrayDataSource(s.getBytes());
        return new DataHandler(byteArrayDataSource);
    }

All it does is to convert the string to bytes using the system's default encoding which is
unlikely to be base64 (it may be ISO-8859-1, UTF-8, Big5, ...).
