The Java based SOAP products include Cape Clear, Shinka, Glue and Juice. I would begin your research with those -- it really depends upon what MOM you are referring to. SOAP by itself is not transport protocol specific, so you could implement the command/control logic in Java, and in theory this would be transparent to HTML, CORBA or MQ Series.
