[aspectj-users] Use Aspectj during web services invocation

[Shanmuga Priya R]

Hi,

     I wanted to use aspectj during invocation of web service from other
service. For that i wanted to know how to specify the jointpoint.

*Web services code:*


*import org.apache.axis2.AxisFault;import
org.apache.axis2.addressing.EndpointReference;import
org.apache.axis2.client.Options;import
org.apache.axis2.client.ServiceClient;import
org.apache.axiom.om.OMAbstractFactory;import
org.apache.axiom.om.OMElement;import org.apache.axiom.om.OMFactory;import
org.apache.axiom.om.OMNamespace;public class MiddleSimpleInterest{
public static void main(String[] args) throws AxisFault    {
 ServiceClient client = new ServiceClient();       Options opts = new
Options();       opts.setTo(new
EndpointReference("http://localhost:8088/axis2/services/SimpleIntJava
<http://localhost:8088/axis2/services/SimpleIntJava>"));
 opts.setAction("urn:findInterest");       client.setOptions(opts);
 OMElement res = client.sendReceive(createPayLoad());
 System.out.println(res);    }   private static OMElement createPayLoad()
 {        OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs = fac.createOMNamespace("http://simpleintjava
<http://simpleintjava>", "ns");        OMElement method =
fac.createOMElement("findInterest", omNs);        OMElement value =
fac.createOMElement("p", omNs);        value.setText("1000");
method.addChild(value);        return method;    }}*

*Corresponding Aspectj code:*
public aspect MiddlewareAspect
{
pointcut beforeaspect():execution(* *.sendReceive(..));

        pointcut beforeexeaspect():execution(* EndpointReference(..));
*        before():beforeaspect()        {
System.out.println("~~~~~~~~~~~~~~~~~~~~~~");
System.out.println("====Before sendReceive=====");
System.out.println("~~~~~~~~~~~~~~~~~~~~~~");         }*
         before():beforeexeaspect()
         {
               System.out.println("~~~~~~~~~~~~~~~~~~~~~~");
               System.out.println("====Before *EndpointReference*=====");
               System.out.println("~~~~~~~~~~~~~~~~~~~~~~");
         }
}

*Error:*

      For the above aspectj code i got the exception "*Advice didn't match*
".


 How can i specify those 2 join points? Is it possible in aspectj?

Thanks,
