Managing Datasource in struts Application

Hi i need to know how to do set up of Oracle data base with struts using Data source.I have defined datasource in struts-config.xml as

data-sources>
        <data-source type="oracle.jdbc.pool.OracleConnectionPoolDataSource">
            <set-property property="URL" 
   value="jdbc:oracle:thin:@192.168.11.106:1521:server"/>
            <set-property property="user" value="SCOTT"/>
            <set-property  property="password" value="TIGER"/>
        </data-source>
    </data-sources>

Then in my action class i am retrieving as

public ActionForward execute(
            ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        System.out.println("In Action of accept");
        String agregno = request.getParameter("agregno");
        System.out.println(agregno);
        boolean valid = Validation.acceptAgent(agregno, getDataSource(request));
        System.out.println("After val");
        System.out.println(valid);
        if (valid) {
            return mapping.findForward("success");
        }
        return mapping.findForward("fail");

    }

I am getting error like getDatasource method does not exist.
