Hi Scott,

Eveyrthing seems to work fine now, except one minor problem. 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));
        } else {
            params.addElement(new Parameter("thumb",
                    javax.activation.DataHandler.class, null, null));
            params.addElement(new Parameter("thumbFileName",
                    new String().getClass(), null, null));
        }
