Time to execute method in EJB

[ptheron]

Hi

Below are two methods in a Remote SessionBean:

from a servlet it takes:
+/- 0.1 ms to call helloWorld()
+/- 0.4 ms to call helloWorldWithLocal()

from a java client it takes:
+/- 3.0 ms to call helloWorld()
+/- 6.0 ms to call helloWorldWithLocal()

The time spend inside helloWorldWithLocal is +/- 0 ms - the question is: why is there such a big time delta between helloWorld() and helloWorldWithLocal()??

public String helloWorldWithLocal () throws RemoteException {


String localStr = "LOCAL BEAN NOT FOUND";
long time1 =System.currentTimeMillis();

try {
LocalHelloHome hh = null;
LocalHello hl = null;
hh = (LocalHelloHome) (new InitialContext()).lookup("java:comp/env/ejb/LocalHelloBean");
hl = hh.create();
localStr = hl.helloWorld();
} catch (Exception e) {
localStr += ", " + e.toString();
}

long time2 =System.currentTimeMillis();
localStr += "; Local time = " + (time2-time1) + " ms";

return "Hello from myEjb.HelloBean" + localStr;
}

public String helloWorld () throws RemoteException {
return "Hello from myEjb.HelloBean";
}
