I guess my mail was way too long for people to actually read it :) Anyway, based on the input of one kind soul, I explored further and finally hit on something that worked. It might not be the right way but it worked for now and I just want to share with the list, in case someone else is banging his head on the wall:
1. Using a customized Encoding Style URI besides Constants.NS_URI_SOAP_ENC always result in an exception something like "Caught SOAPException (SOAP-ENV:Client): No Serializer found to serialize a 'org.apache.soap.rpc.Parameter' using encoding style 'http://xxx.com/test'. 2. Using Constants.NS_URI_SOAP_ENC works. I made a mistake in my serializer. I forgot the end tag "</PurchaseOrder>". So if I had added sink.write("</" + context + '>'); It worked for me.
