Webservice invocation question ?

Question

hi,
i had never create nor call a webservice... here the work i have to do :
my environnement is : weblogic 8.1, J2EE 1.3, eclipse.
i am developping a web application, this web applciation has a login form to enable user to connect to the application.
A web service already exits in another weblogicserver (i have the ip, port number, methode name....), this webservice and more specialy its methode checkAuthorization takes two parameters (username,password) and send back 3 result parameteers (res1, res2, res3).
what i have to do, is to create a helper class, let's say "webserviceClient" which invoke thsi webservice and depending on the result, authorize or not the connection.
i began to read the sun tutorial, i understand that there is two ways to do this job, using JAX-RPC or SOAP!!!!
my question is : are this componenet applicationserver dependent, in another way, does weblogic server 8.1 conatins the necessary package to do that ?
my second question is, what is the more easiest way to that ?
i have not a lot of time for doing that :-))),
thanks for your help

Hi Abhi,
Are your Web Service and Enterprise Application which call the web service both are running on the same server?
I think you should check web service processing time of the web service at server side(inside your web service/method) not at the client side. This way you will get better idea about how much time client takes to connect to web service and getting response back.
get elapsed time as Chicon specified at client side, and put similar at server side to get web method processing time like:
// This is you web method
public String webMethod() {
    long webServiceStart = System.currentTimeMillis();
    // Web Service Implementation
    // Web Service Implementation
    long webServiceEnd = System.currentTimeMillis();
    System.out.println("Web Service processing time : " + (webServiceEnd-webServiceStart) + " milliseconds");
}You should get above time almost same in both the case.
Because standalone application needs to connect to server explicitly where as an enterprise application running on same server as your web service is will get it invoked fast compared to standalone application.
