Java – Soap client service using java without WSDL – How to

javasoapweb serviceswsdl

I use JAX-WS thats ships with jdk to create soap client. Now, the service provider isn't exposing the wsdl. How to create soap client without wsdl, if I know the provided services?

Edit: I have the freedom to use any soap api/tool, not restricted to JAX-WS.

Edit2: Here is the message that is shown when the service url is hit.
Metadata publishing for this service is currently disabled.
And suggests to configure service behavior configuration. I understand the service is done in .Net. But How do I use the provided service behavior related details to access the service in Java?

You can use HttpClient directly but you must hand-code each xml message you send and parse each message you receive. You can also manually create your objects that match your xml and use jaxb to marshall/unmarshall messages.

Java – How to call one constructor from another in Java

Yes, it is possible:

public class Foo {
    private int x;

    public Foo() {
        this(1);
    }

    public Foo(int x) {
        this.x = x;
    }
}

To chain to a particular superclass constructor instead of one in the same class, use super instead of this. Note that you can only chain to one constructor, and it has to be the first statement in your constructor body.
