Hi everyone,

I'm learning about web services, and while i'm reading some tutorials, i was hoping someone could write me a simple java code. The web service operation is Login(UserID, Password) and returns a boolean (that's what i was told). I would really appreciate if someone would write me an example on how to send the user and password and then read the boolean.

Thank you.

Hi!
What is the purpose with your exercise? To learn about web services or to implement a web service authentication mechanism?
If you want an authentication mechanism for web services, then basic authentication can be used.
I have written a document which both shows how to write JAX-WS web services as well as how to use basic authentication with JAX-WS web services.
The document can be freely downloaded at: http://www.javaforum.se/jforum/posts/list/549.page
Best wishes!

Hi, thanks for the reply, my purpose was to see how i can use Java to access a web service. I don't really care about implementing a web service

Hi again,

I'm having a problem with the tutorial, i created a web service that adds 2 ints, and a servlets that consumes it, it works great. But then i wrote the other example (using J2SE) and even tho it has the same settings as the servlet, it doesn't work, it says:

C:\Users\Infernal\Documents\Java\CalculatorWSClient\src\packa\Main.java:8: package pack does not exist
pack.CalculatorWSService service = new pack.CalculatorWSService();

when i try to run it. Like i said, both servlet and application have the same settings, using the same Web Service Client, one of them works, the other doesn't You have any ideea why ?

No idea, really. All the examples have been tested, so I know that they work. I suspect that you may have missed some detail in the instructions.
I do see that you have made modifications to the code from the document. I suggest starting over from scratch and making sure that you follow each step in the instructions exactly as they are written, without any modifications. Once you have the example up and running, you can start modifying it to your hearts content.
Best wishes!

Oh, forgot to post, it was a dumb thing, if i ran the application using Shift + F6 in NetBeans i get that error, if i run it using right click + Run, it works

Thanks for your help.
