Driver not found Exception in Web Service example

Hi

I am creating a web service and web service client in Eclipse IDE.

From the client I am able to access the methods of the web service, but when I write some code related to database( in the method of web service), I get Error that It is unable to locate the driver, But I have set the related jar file in the class path of the web service project.

After the above error I get the following Error:

[INFO] Unable to sendViaPost to url[http://localhost:5050/NewOracleMod1/services/Account.AccountHttpSoap11Endpoint/]
