This is a "quirk" of the MimePartSerializer. It is used to serialize InputStream, DataSource, MimeBodyPart and DataHandler. When a null value is passed in for serialization, the serializer (for some reason) chooses to serialize it as an Object. That's why you get the mismatch.
I'm going to change the code to use the type specified to the serializer when serializing a null. You can either grab the source (http://cvs.apache.org/viewcvs.cgi/*checkout*/xml-soap/java/src/org/apac he/soap/encoding/soapenc/MimePartSerializer.java?rev=HEAD&content-type=t ext/plain), compile it and use it, or wait until tomorrow and get a nightly build (http://cvs.apache.org/dist/soap/nightly/).

When there is nothing to send as argument I am passing in null and thats throwing exception. Please look at the bold lines of my code below. I am passing in the type of the argument as javax.activation.DataHandler.class, but it still takes it as Object. See the exception after the code. Look at the 6th argument of the method. It is assuming the object type as "Object" not "javax.activation.DataHandler" Vector params = new Vector(); params.addElement(new Parameter("sessionID", long.class, new Long(sessionID), null)); params.addElement(new Parameter("containerID", containerID.getClass(), new String(containerID), null)); params.addElement(new Parameter("xmlString", xmlString.getClass(), new String(xmlString), null)); DataSource ds = new ByteArrayDataSource(sourceBytes, "application/octet-stream"); DataHandler dh = new DataHandler(ds); params.addElement(new Parameter("source", javax.activation.DataHandler.class, dh, null)); // params.addElement(new Parameter("encodedSource", encodedSource.getClass(), new String(encodedSource), null)); params.addElement(new Parameter("sourceFileName", sourceFileName.getClass(), new String(sourceFileName), null)); if (thumbBytes != null && thumbFileName!=null) { ds = new ByteArrayDataSource(thumbBytes, "application/octet-stream"); dh = new DataHandler(ds); params.addElement(new Parameter("thumb", javax.activation.DataHandler.class, dh, null)); params.addElement(new Parameter("thumbFileName", thumbFileName.getClass(), new String(thumbFileName), null));
