I made a WSS4JInInterceptor in a spring bean configuration file as follows
<?xml version="1.0" encoding="UTF-8"?>

The ServerPasswordCallBack.java looks like the following
package net.ma.soap.ws.service;
import java.io.IOException;
import java.util.ResourceBundle;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;
import org.apache.wss4j.common.ext.WSPasswordCallback;
public class ServerPasswordCallback implements CallbackHandler {
private static final String BUNDLE_LOCATION = "zuth";
private static final String PASSWORD_PROPERTY_NAME = "auth.manager.password";
private static String password;
static {
final ResourceBundle bundle = ResourceBundle.getBundle(BUNDLE_LOCATION);
password = bundle.getString(PASSWORD_PROPERTY_NAME);
}
#Override
public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException {
WSPasswordCallback pc = (WSPasswordCallback) callbacks[0];
pc.setPassword(password);
}
}
With the password verification, everything work just fine.
I'd like to know if there's any other way to enhance the handle(Callback) method to make it more sophisticated so it would be able to check more than just one parameter, for example if i can make it check an access token, it would be much more better.
the password property is defined in zuth_fr_FR.properties file as follows
auth.manager.password=najah
If you want to do some custom validation on your username and token (such as verify against a directoryservice using LDAP or something similar) you can write your own custom UsernameTokenValidator overriding verifyPlaintextPassword(UsernameToken usernameToken) of UsernameTokenValidator and hook it up to your WSS4JInInterceptor adding the following to your bean definition
<property name="wssConfig">
<ref bean="usernameTokenWssConfig"/>
</property>
And add the referenced class to your codebase:
#Component("usernameTokenWssConfig")
public class usernameTokenWssConfigWSSConfig {
public usernameTokenWssConfig() {
setValidator(WSSecurityEngine.USERNAME_TOKEN, new CustomUsernameTokenValidator());
setRequiredPasswordType(WSConstants.PASSWORD_TEXT);
}
}

This is the client code that consumes the soap web service.
before adding the security configuration, the server was up and running and the client consumed the function of the soap api successfully but after the security modification, when the client attempts to use the web service function i get this error

I tried to manually add some wsse headers in the soap envelope but it didn't work.
I solved my problem by modifying the AuthServiceFactory.java class and the ClientPasswordCallback.java and the descriptor deployment file and i added a auth2_Fr_fr.properties file.

public static void main(String[] args) {
AuthServiceFactory authSer = new AuthServiceFactory();

I'm new to Spring and trying to get a example to work. But my application loads twice each time it starts. I think it could be a context problem because of my internet research and I have just one context.xml.

My code of the TraderApplication Class is:
... skipped imports ....
#SpringBootApplication
public class TraderApplication implements CommandLineRunner{
private static final Logger log = LoggerFactory.getLogger(TraderApplication.class);
#Autowired
protected ObjectMapper objectMapper;
#Autowired

TraderApplication app = (TraderApplication) applicationContext.getBean("TraderApplication");
app.run(identifier, password, apiKey);
} catch (Exception e) {
log.error("Unexpected error:", e);
}
}
You mention in your comments above you got this working by removing SpringApplication.run(TraderApplication.class, args); but this would be removing spring-boot from your application so I'm going to assume since your question has a tag of [spring-boot] that this is not what you wanted. So here is an alternative way that you can configure beans using your xml.
#ImportResource({"classpath*:public-api-client-spring-context.xml"}) //Proper way to import xml in Spring Boot
#SpringBootApplication
public class TraderApplication implements CommandLineRunner {
...code you had before goes here
#Autowired
TraderApplication app;
#Override
public void run(String... args) throws Exception {
.. your parsing logic here
app.run(identifier, password, apiKey); //Now uses the autowired instance
}
}
You didn't list your pom.xml or build.gradle but it's important to remember that components you have registered in your context xml may be automatically configured in Spring Boot and you may not need to register them yourself in your xml.(Depending on which items you have starters for in your build file)
I browsed around 30 webpages and 50 articles about this and it's still not working.

And in resources folder is my application.properties file which contains only app.name=Phil
Exception in thread "main"
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
Line 12 in XML document from class path resource [SpringBeans.xml] is
invalid; nested exception is org.xml.sax.SAXParseException;
lineNumber: 12; columnNumber: 81; cvc-complex-type.2.4.c: The matching
wildcard is strict, but no declaration can be found for element
'context:property-placeholder'.
I really tried most of solutions which I found at stackoverflow and few other forums. I`m really new in spring and I will appreciate any help.
In your springbeans.xml you've specified the location as "classpath*:application.properties" classpath with a * whereas in your HelloWorldService.java you've specified the location as "classpath:application.properties". There is a discrepancy in the two locations.
Besides the problem lies in the SpringBeans.xml schema declaration. It is incorrect & incomplete.
After the context declaration http://www.springframework.org/schema/context/spring-context-4.0.xsd is missing
check this this & this
Ideally it should be
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
I am unable to comment -
What i see is you are writing : <context:property-placeholder location="classpath*:application.properties"/>
Why is there a * after classpath.
It should work with - <context:property-placeholder location="classpath:application.properties"/>
Else -
You can use -
<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:application.properties</value>
</list>
</property>
<property name="ignoreUnresolvablePlaceholders" value="true"/>
</bean>
In you Heloworld bean
<bean id="helloworld" class ="package.HelloWorldService" >
<property name="name" value="${app.name}" />
</bean>
I've been looking around and haven't found any examples of using spring annotations to generate JMX notifications. I have found examples using #ManagedAttribute and #ManagedOperation.
Thanks
-Bill
Here you go:
import java.util.concurrent.atomic.AtomicLong;
import javax.management.Notification;
import org.springframework.jmx.export.annotation.ManagedOperation;
import org.springframework.jmx.export.annotation.ManagedResource;
import org.springframework.jmx.export.notification.NotificationPublisher;
import org.springframework.jmx.export.notification.NotificationPublisherAware;
#ManagedResource
public class JMXDemo implements NotificationPublisherAware {
private final AtomicLong notificationSequence = new AtomicLong();
private NotificationPublisher notificationPublisher;
#Override
public void setNotificationPublisher(
final NotificationPublisher notificationPublisher) {
this.notificationPublisher = notificationPublisher;
}
#ManagedOperation
public void trigger() {
if (notificationPublisher != null) {
final Notification notification = new Notification("type",
getClass().getName(),
notificationSequence.getAndIncrement(), "The message");
notificationPublisher.sendNotification(notification);
}
}
}
And in your Spring configuration file you must use something like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

You can then access above bean with JConsole and trigger notifications with the operation trigger(). Be sure to subscribe to the notifications. :)
You can add notification details (Notification MetaData) to the exposed JMX MBean as well using #ManagedNotifications annotation.
Apply bellow annotation on Class JMXDemo along with #ManagedResource annotation
#ManagedNotifications({ #ManagedNotification(name = "javax.management.Notification", notificationTypes = { "notification type" }, description = "notification description") })
Above details will show the notification details under JConsole Notification details option.
