Background

I call WebService in Java and report an error when I call new xxxxxxxservice().

Cause analysis

When WebService creates new xxxxxxxservice(), it needs to load the URL in xxxxxxxservice first. If the URL is not loaded or the URL is null, the above error may be reported.

There are two solutions

Method 1: Add the url of the webservice’s access address to the static method, as follows:

static {
        URL url = null;
        WebServiceException e = null;
        try {
            url = new URL("http://127.0.0.1:8088/ynhrs/services/info?wsdl");
        } catch (MalformedURLException ex) {
            e = new WebServiceException(ex);
        }
        BIZSERVICE_WSDL_LOCATION = url;
        BIZSERVICE_EXCEPTION = e;
    }

You can also configure the address of WebService file, etc

Method 2: directly add the URL to new xxxxxxxservice(), as follows:

Ynhrsspspservice pspService = new Ynhrsspspservice(new URL("http://127.0.0.1:8088/ynhrs/services/info?wsdl"));

http://127.0.0.1:8088/ynhrs/services/info?wsdl is the URL of webservice
