Thanks Bobby. I would really appreciate if you can give me some ideas to work around this problem.

Since I've seen your original email look different after it's been
replied to with other people's emailers, I'm not going to use the
"ampersand" sign here but will use "[AMP]" to mean the sign so things
stay how I wrote them (hopefully).

I tried a simple echoString() method with no handlers and sent "bert
[AMP] ernie" and got back:

result: "bert [AMP] ernie"
Request has:
bert [AMP]amp; ernie
Response has:
bert [AMP]amp; ernie

So far, so good.

When I throw a simple handler like yours on there I get:

result: "bert [AMP]amp;[AMP]amp; ernie"
Request has:
bert [AMP]amp;amp;[AMP]amp;amp; ernie
Response has:
bert [AMP]amp;amp;[AMP]amp;amp; ernie

When you don't use handlers, the jaxrpc runtime creates the xml itself
and parses the response, so it encodes the symbol and decodes it later.
When you add a handler, even if the handler does nothing, the runtime
has to create a SOAPMessage to pass into the handler's handleXYZ()
methods. So I think [AMP]->[AMP]amp;->[AMP]amp;amp; since the symbol is
being escaped twice. (Not sure how it gets doubled as well.)

I can't think of any workaround now, but will look at the way we create
the SOAPMessage to see what we can do about it.
