[aspectj-users] Intercepting web services... ;)

[Sunny Saxena <matrixsu_in@xxxxxxxxx>]

If i run this with aspectJ compiled classes, I am getting the following message:

 

java.lang.reflect.InvocationTargetException

 

if compiled using normal java, it runs absolutely fine.

 

can anyone tell me what is it that i am doing wrong??

 

The codes are as given...

 

The webservice client code:

 

public class Client
{
    public static void main(String [] args)
    {
        try {
           
            String endpointURL = "http://localhost:8080/axis/services/MyService";
            String textToSend = "Sunny";

           
            Service service = new Service();
            Call call = (Call) service.createCall();

            call.setTargetEndpointAddress( new java.net.URL(endpointURL) );
            call.setOperationName( new QName("http://example3.userguide.samples", "serviceMethod") );
            call.addParameter( "arg1", XMLType.XSD_STRING, ParameterMode.IN);
            call.setReturnType( org.apache.axis.encoding.XMLType.XSD_STRING );

            String ret = (String) call.invoke( new Object[] { textToSend } );
           
            System.out.println("You typed : " + ret);
        } catch (Exception e) {
            System.err.println(e.toString());
        }
    }
}

 

The service code:

 

public class MyService
{
    public String serviceMethod(String arg)
    {
        return arg;
    }
}

 

The aspect code:

 

public aspect Cept {

   before () : execution(public String serviceMethod(String)) {
       System.out.println("print this");
   }

}
