What I do is I have an object that I store in the Servlet application scope
memory that interface with my Axis WebService.
In the JSP that do the work. I simply do:
// Retreive the WebService interface object that we cache as an
// application scoped object.
WSInterfacews = (WSInterface)application.getAttribute("ws") == null
? new WSInterface(endPoint, application)
: (WSInterface)application.getAttribute("ws");
ws.doTheThing("parmam1");
....
Where WSInterface.java looks like:
class WSInterface {
// ReportNet service
MyServiceLocator service = null;
MyPortType binding = null;
// Application context
ServletContext application = null;
// Tranformation factory
TransformerFactory tf = null;
public WSInterface(String endPoint, ServletContext app) throws Exception {
// Did we received a valid endPoint
if ( endPoint == null)
throw new Exception("Invalid endPoint provided: ["+ endPoint +"]");
// Instantiate the transformer factory
tf = TransformerFactory.newInstance();
// Retreive the service
service = new MyServiceLocator();
binding = service.getMyPort(new java.net.URL(endPoint));
// Keep a handle to the application context to retreive the ressources
application = app;
}
public void doTheThing(String thing) {
// Implement doTheThing
}
}
Enjoy!
Sylvain.

Hello, Juergen
Thank you very much.
Actually, I have studied Web Service for a long time.
I am familiar with the concept of Web Sercice and have read most article
on
http://www.ibm.com/developerWorks/webservices/ and other sites.
I have tried to use WSTK(IBM),jwsdp(JAVA) and AXIS(APACHE) and the
examples on them.
But, my problem is how to call the example or other service on internet
like
StockQuote within a JSP page.
Because I am not familiar with Java and JSP technique, I don't get the
point how to implement a service call via JSP page.
Do I need to write a service call Java and compile to a class and use it
like a
<jsp:useBean> ?
Thanks again...
Jayhung
