Web service XML-Java conversion

Question

Hello,
It's said in BEA documentation that "web services tries to convert the XML
data inside the body of the SOAP message into one of the Java data types
listed
in "Supported Data Type...." see link for quote source.
Does this mean, BEA SOAP servlet does javaBean serialization/deserialization
automaticly
without user defining any data type mapping ?
in Apache SOAP implementation, user has to add a mapping element to specify
how SOAP
server should handle custom parameters such as a java object.

ur prompt response is most appreciated.
thank you and regards.

webservice receives xml data as parameter or webservice use SOAP XML letter to receive data?
if you get xml as parameter then you have to process XML to get java objects, if it is SOAP letter, then webservice has done job for you and you get set of java objects that should be persisted.
To persist data easiest way is to use EJB 3.0 and JPA. Webservice create using EJB 3.0 is easy as well.
to convert data in XML into java objects you can use DOM document + xPath or http://commons.apache.org/digester/ or something else, depending on size of XML doc
No need to be muddying the waters with such a heavyweight solution at this point. The guy's a relative newbie, and also has stated that the number of messages is very small. The simple APIs suggested above are much more in order, otherwise the guy's got a massive learning curve ahead of him, for no real benefit. Besides, you've not mentioned ESBs, message routing, EIP and the like, so your buzzword-compliance score has dropped dramatically :-)
