Subject RE: Struts and webservices
Date Mon, 19 Jan 2004 20:31:39 GMT

Hi Guido,

I have recently migrated a proprietary(non-standard) web service
implementation in a Struts based web app using Apache Axis
http://ws.apache.org/axis/.

Struts and Axis are both servlets, Axis handles all XML messages and
Struts handles all form processing. If all you need is another way to
process your web service calls just use Axis or some other web service
framework and leave Struts for form processing, templating/tiles and
validation. The code snippet you have provided is exactly what a web
service framework will do for you.

HTH,

Greg
