I checked on server and found Axis was not prperly configured whenver i open http://localhost:7001/axis/happyaxis.jsp
likn say Error 503--Service Unavailable and on the weblogic console i am getting following exception

<Aug 13, 2009 12:53:43 PM IST> <Error> <Deployer> <BEA-149231> <Unable to set th

Even i have set <prefer-web-inf-classes>true</prefer-web-inf-classes> into weblogic.xml file in Axis application and copy /web-inf/lib folder (xml-apis.jar,xercesImpl.jar) after that it's not able to set.

Thanks for suggestion but Sammeta Calculator class is simple interface...so from my side there is no fault in the Calculator ...it might be some thing else....

I have created my web service using Axis 1.4 and it's sussces fully deployed on weblogic 8.1.

I am not able to understands what is reason behind it...?
Client code is ---

CalculatorService service = new CalculatorServiceLocator();
Calculator calc = service.getcalculator();
System.out.println("15 + 6 = " + calc.add(15, 6));
System.out.println("15 - 6 = " + calc.subtract(15, 6));
