java - Can we implement method overloading in web service class?

Question

I would like to implement method overloading in the Java web service class as follows:

public String myMethod(User user)
{
    // My code
} 

public String myMethod(User[] user)
{
    for(int i=0; i<user.length; i++)
    {
        myMethod(user[i]);
    }
}

If I forward a single User object to myMethod(), it should trigger the first method and if I send an array of Users, it should trigger the second method.

In the WSDL file it shows only a single method. However, if I try to call @WebMethod(operationName="") for both calls, I am unable to generate the WSDL file.

Answer 1

Operation overloading is not allowed for web services.
It is explicitely prohibited in WS-BP and WSDL 1.2 also disallows it.
Even if you found a stack that has some support for this I would recommend not to follow this approach.
Overloading is an OO concept. Don't try to apply them to Service Oriented paradigm
