How deserialize XML data in application

Hi,
I have this problem:
I use Apache SOAP for Java. I create a request on a client and send it on
a server. But aplication, which is as server doesn't run under a Tomcat. It
is classic Java aplication, which listen on a specific port.
And here is problem. I don't know, how deserialize a data,
which I get and how serilaize a response.
It's possible with Apache SOAP, or I must use any other XML parser
(xerces?).

Thanks,

Jarda
