Handling custom exceptions - java web services

My first post here, please be patient and correct me when necessary ...

I am building a simple NetBeans web service with GlassFish. NetBeans helps a lot in creating code for new web services and their operations, but one thing drives me crazy, though - handling web service exceptions. Operation like:

@WebMethod(operationName = "checkUserExist")
public String checkUserExist(@WebParam(name = "login") String login, @WebParam(name = "password") String password) throws LoginException {

    String auth_code = "";
    bk_end.Validate val = new bk_end.Validate();

    boolean isValidated = val.check(login, password);

    if(isValidated)
    {
        auth_code = val.return_AuthCode();
        bank_services.CustomerSerice.setAuth_Code(auth_code);
        return auth_code;
    }

    throw new LoginException("Something is wrong!");

}

and exception class:

public class LoginException extends Exception
{
    String message;


    public LoginException(String message)
    {
        super();
        this.message = message;
    }

    public String getErrorMessage()
    {
        return this.message;
    }
}

throws a massive Exception Details: java.lang.reflect.InvocationTargetException plus tons of other exceptions .. I understand this is a very dangerous question, but after many hours of trying all kinds of things I just don’t know what to do. I read about @WebFault stuff, but had no idea how to specify it correctly (attach my exception to a specific method ..)

Please help, all ideas are more than welcome!

LoginException.toString() - :

@Override
public String toString() {
    String s = getClass().getName();
    return (message != null) ? (s + ": " + message) : s;
}

- :

try {
