Recently I had the „chance“ to consume an old school WebService in good old SOAP on top of that it was a C# WebService using the dataset construct which is in itself a world of pain… but we will not talk about that here

A more easy thing to tackle is the NTLM authentication, below is how I implemented it using Spring and Spring boot :

1. Define a set of custom properties in the application.yaml file

ws:
base-url: "http://host/ws.asmx?wsdl"
username: "myusername"
password: "mypassword"
authentication: "NTLM"
2. Map the properties in application.yaml to a Java class


import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.stereotype.Component;


@Component
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "app")
@Data
public class YAMLConfig {

private Ws ws;

@Data
public static class Ws {
private String baseUrl;
private String username;
private String password;
private String authentication;


}

}

//Injection and other properties omitted for brevity
public void consume(){

JaxWsProxyFactoryBean factory1 = new JaxWsProxyFactoryBean();
factory1.setServiceClass(EntityInformationSoap.class);
factory1.setAddress(yamlConfig.getWs().getBaseUrl());
factory1.setUsername(yamlConfig.getWs().getUsername());
factory1.setPassword(yamlConfig.getWs().getPassword());

EntityInformationSoap service = (EntityInformationSoap) factory1.create();
Client client = ClientProxy.getClient(service);

HTTPConduit conduit = (HTTPConduit) client.getConduit();
conduit.getAuthorization().setAuthorizationType(yamlConfig.getWs().getAuthentication());
conduit.getAuthorization().setUserName(yamlConfig.getWs().getUsername());
conduit.getAuthorization().setPassword(yamlConfig.getWs().getPassword());

HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setConnectionTimeout(36000);
httpClientPolicy.setAllowChunking(false);
conduit.setClient(httpClientPolicy);
}
