I have two application e.g) A, B
A has a Saga
B is just web application
A sent Command messages to B and
B sent exception for that Command to A's Saga and A's Saga received well
and B have a #ExceptionHandler which I hope to be invoked but it's not working
How can I make them be invoked?
EDIT
this is A application's Saga that sends command messages to B application
and deals with exception which B sent
#Saga
public class OrderSaga {
#Autowired
private transient CommandGateway commandGateway;
#StartSaga
#SagaEventHandler(associationProperty = "orderId")
public void handle(CreateOrderEvent evt) {
String paymentId = UUID.randomUUID().toString();
SagaLifecycle.associateWith("paymentId", paymentId);
commandGateway.send(new CreatedPaymentCommand(paymentId, evt.getUserId(),evt.getFoodPrice())).exceptionally(exp -> {
System.out.println("got it");
System.out.println(exp.getMessage());
return null;
});
}
}
this is B application that throws exception for test
#Aggregate
#NoArgsConstructor
public class PaymentAggregate {
#AggregateIdentifier
private String paymentId;
private String userId;
private PaymentStatus status;
#CommandHandler
public PaymentAggregate(CreatedPaymentCommand cmd) {
throw new IllegalStateException("this exception was came from payment aggregates");
// AggregateLifecycle.apply(new CreatedPaymentEvent(cmd.getPaymentId(),
// cmd.getUserId(),cmd.getMoney()));
}
#ExceptionHandler(resultType = IllegalStateException.class)
public void error(IllegalStateException exp) {
System.out.println(exp.getMessage());
}
// I want this #ExceptionHandler to be invoked
#EventSourcingHandler
public void on(CreatedPaymentEvent evt) {
this.paymentId = evt.getPaymentId();
this.userId = evt.getUserId();
}
}
A application catch exception well like below
2021-08-24 11:46:43.534 WARN 14244 --- [ault-executor-2] o.a.c.gateway.DefaultCommandGateway : Command 'com.common.cmd.CreatedPaymentCommand' resulted in org.axonframework.commandhandling.CommandExecutionException(this exception was came from payment aggregates)
got it
this exception was came from payment aggregates
but B is not I thought that B's #ExceptionHandler will catch that exception
in short, How can I make B's #ExceptionHandler to be invoked
It doesn't work right now because the exception is thrown from the constructor of your aggregate.
As you are using a constructor command handler, there is no instance present yet.
And without an instance, Axon Framework cannot spot the #ExceptionHandler annotated method you've set up.
This is the only missing point for the exception handlers at this stage. Honestly, the reference guide should be a bit more specific about this. I am sure this will change in the future, though.
There's a different approach for having a command handler that constructs the aggregate and that can use the #ExceptionHandler: with the #CreationPolicy annotation. The reference guide has this to say about it, by the way.
Thus, instead of having a constructor command handler, you would set up a regular command handler using the AggregateCreationPolicy.ALWAYS.
That would adjust your sample like so:
#Aggregate
#NoArgsConstructor
public class PaymentAggregate {
#AggregateIdentifier
private String paymentId;
private String userId;
private PaymentStatus status;
#CommandHandler
#CreationPolicy(AggregateCreationPolicy.ALWAYS)
public void handle(CreatedPaymentCommand cmd) {
throw new IllegalStateException("this exception was came from payment aggregates");
// AggregateLifecycle.apply(new CreatedPaymentEvent(cmd.getPaymentId(),
// cmd.getUserId(),cmd.getMoney()));
}
#ExceptionHandler(resultType = IllegalStateException.class)
public void error(IllegalStateException exp) {
System.out.println(exp.getMessage());
}
// I want this #ExceptionHandler to be invoked
#EventSourcingHandler
public void on(CreatedPaymentEvent evt) {
this.paymentId = evt.getPaymentId();
this.userId = evt.getUserId();
}
}
Please give this a try in your application, #YongD.
I am trying to write a Spring WS client using WebServiceGatewaySupport. I managed to test the client for a successful request and response. Now I wanted to write test cases for soap faults.
public class MyClient extends WebServiceGatewaySupport {
public ServiceResponse method(ServiceRequest serviceRequest) {
return (ServiceResponse) getWebServiceTemplate().marshalSendAndReceive(serviceRequest);
}
#ActiveProfiles("test")
#RunWith(SpringRunner.class)
#SpringBootTest(classes = SpringTestConfig.class)
#DirtiesContext
public class MyClientTest {
#Autowired
private MyClient myClient;
private MockWebServiceServer mockServer;
#Before
public void createServer() throws Exception {
mockServer = MockWebServiceServer.createServer(myClient);
}
}
My question is how do i stub the soap fault response in the mock server, so that my custom FaultMessageResolver will be able to unmarshall soap fault?
I tried couple of things below, but nothing worked.
// responsePayload being SoapFault wrapped in SoapEnvelope
mockServer.expect(payload(requestPayload))
.andRespond(withSoapEnvelope(responsePayload));
// tried to build error message
mockServer.expect(payload(requestPayload))
.andRespond(withError("soap fault string"));
// tried with Exception
mockServer.expect(payload(requestPayload))
.andRespond(withException(new RuntimeException));
Any help is appreciated. Thanks!
Follow Up:
Ok so, withSoapEnvelope(payload) I managed to get the controller to go to my custom MySoapFaultMessageResolver.
public class MyCustomSoapFaultMessageResolver implements FaultMessageResolver {
private Jaxb2Marshaller jaxb2Marshaller;
#Override
public void resolveFault(WebServiceMessage message) throws IOException {
if (message instanceof SoapMessage) {
SoapMessage soapMessage = (SoapMessage) message;
SoapFaultDetailElement soapFaultDetailElement = (SoapFaultDetailElement) soapMessage.getSoapBody()
.getFault()
.getFaultDetail()
.getDetailEntries()
.next();
Source source = soapFaultDetailElement.getSource();
jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("com.company.project.schema");
Object object = jaxb2Marshaller.unmarshal(source);
if (object instanceof CustomerAlreadyExistsFault) {
throw new CustomerAlreadyExistsException(soapMessage);
}
}
}
}
But seriously!!! I had to unmarshall every message and check the instance of it. Being a client I should be thorough with all possible exceptions of the service here, and create custom runtime exceptions and throw it from the resolver. Still at the end, its been caught in WebServiceTemplate and re thrown as just a runtime exception.
You could try with something like this:
#Test
public void yourTestMethod() // with no throw here
{
Source requestPayload = new StringSource("<your request>");
String errorMessage = "Your error message from WS";
mockWebServiceServer
.expect(payload(requestPayload))
.andRespond(withError(errorMessage));
YourRequestClass request = new YourRequestClass();
// TODO: set request properties...
try {
yourClient.callMethod(request);
}
catch (Exception e) {
assertThat(e.getMessage()).isEqualTo(errorMessage);
}
mockWebServiceServer.verify();
}
In this part of code mockWebServiceServer represents the instance of MockWebServiceServer class.
In my project based on Spring Boot 1.3.3, I integrated MyBatis with mybatis-spring-boot-starter 1.1.1 as persistence layer, all CRUD operation seems working fine separately, but the integration tests failed and I found the DB operation gets blocked in asynchronous task.
The test code looks like this:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = SapiApplication.class)
#Transactional
public class OrderIntegrationTest {
#Test
public void shouldUpdateOrder() throws InterruptedException{
Order order1 = getOrder1();
orderService.createOrder(order1);
Order order1updated = getOrder1Updated();
orderService.updateOrderAsync(order1updated);
Thread.sleep(1000l);
log.info("find the order!");
Order order1Db = orderService.findOrderById(order1.getOrderId());
log.info("found the order!");
assertEquals("closed", order1Db.getStatus());
}
}
The expected execution order is createOrder() -> updateOrderAsync() -> findOrderById(), but actually the execution order is createOrder() -> updateOrderAsync() started and blocked -> findOrderById() -> updateOrderAsync() continued and ended.
Log:

The problem you see is caused by the fact that the whole test method shouldUpdateOrder is executed in one transaction. This means that any update operation that is executed in the thread that runs shouldUpdateOrder locks the record for the whole duration of the transaction (that is till exit from test method) and that record cannot be updated by another concurrent transaction (that is executed in async method).
To solve the issue you need to change transactions boundaries. In your case the correct way to emulate real life usage is to
create order in one transaction and finish the transaction
update order in another transaction
check that update is executed as expected in yet another transaction
I'm trying to get EJB to work with Glassfish v3. I'm working on a Java EE Web application with Servlets.
When I deploy this web app to Glassfish, it registers the EJB class into the
java:global JNDI tree. But, when I try to inject an instance of this into my
Servlet I got a NameNotFoundException.
When I look at the logs of my server, the Servlet tries to do the look up in java:comp/env.
Can someone help me to solve this?

My guess is that you specified names, mapped names and what have you. This is not needed.
Something like the following should work:
EJB:
#Stateless
public class MyBean {
// ...
}
Servlet:
#WebServlet(urlPatterns="/someurl")
public class MyServlet extends HttpServlet {
#EJB
private MyBean myBean;
#Override
public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// ...
}
}
UPDATE:
After seeing your code, the problem is not the injection of the EJB into the Servlet, but the injection of JpaUserDao in Authenticator.
You are injecting it by class, but this will not work since JpaUserDao implements a business interface: UserDao. Because it implements such an interface, there will be no local-view created. As a result, you have to inject using the interface:
#Stateless
public class Authenticator {
private String userFullName;
private Long userId;
#EJB
private UserDao userDao;
// ...
}
As an extra note, the concept of your Authenticator bean is not going to work. It's a stateless bean and its instance variables will have no meaning to the outside world. Thus, getUserFullName() is not guaranteed to return the result you think it will return. It may happen to work momentarily for you in a test when the container happens to select the same bean instance, but this will not work in general.
Even when you hold on to the reference of an Authenticator, it will still not work. The thing is you get a proxy, and the container will potentially direct every call to it to another instance. Think of it as a URL to servers in a web farm where a browser does a call to. You have no guarantee that two successive will go to the exact same physical server.
The authentication that you're trying to do there should be handled by a bean in the web layer and the authentication details put in the HTTP session (additionally, you should maybe use container authentication as well, but that's a whole other thing that's too off-topic here)
There are several ways for injecting a EJB. The most common and simplest solution would be via Dependency Injection as mentioned Arjan Tijms answer.
Another way would be to get a reference via InitialContext.lookup().
In this approach you can choose which lookup name you pass:
Use the class-name of the declaring Bean-Interface:
String jindiName = BeanInterface.class.getName();
InitialContext ctx = new InitialContext();
BeanInterface bi = ctx.lookup(jndiName);
This also works for a remote lookup from any stand-alone client because the interface is public.
Use the JINDI name of the component naming environment:
String jndiName = "java:comp/env/yourejb"
// same as shown above
This will only work inside the same container because the "outside world" do not have access to to the component naming environment.
For a better understanding of jndi names have a look at this.
I hope this helpes, have Fun!
How do I access a Remote EJB component from a stand-alone java client?
Step 1. Use the no-arg InitialContext() constructor in your code.
The most common problem developers run into is passing specific JNDI bootstrapping properties to InitialContext(args). Some other vendors require this step but GlassFish does not. Instead, use the no-arg InitialContext() constructor.
Step 2. Pass the global JNDI name of the Remote EJB to InitialContext.lookup()
Stand-alone java clients do not have access to a component naming environment (java:comp/env) or to the #EJB annotation, so they must explicitly use the global JNDI name to lookup the Remote EJB. (See here for more information on how global JNDI names are assigned to EJB components) Assuming the global JNDI name of the Remote EJB is "FooEJB" :
For Beans with a 3.x Remote Business interface :
Foo foo = (Foo) new InitialContext().lookup("FooEJB");
Note that in the EJB 3.x case the result of the lookup can be directly cast to the remote business interface type without using PortableRemoteObject.narrow().
For EJB 2.1 and earlier session/entity beans :
Object homeObj = new InitialContext().lookup("FooEJB");
FooHome fooHome = (FooHome)
PortableRemoteObject.narrow(homeObj,FooHome.class);
Foo foo = fooHome.create(...)
Step 3. Include the appropriate GlassFish .jars in the java client's classpath.
For GlassFish 3.
Include $GLASSFISH_HOME/glassfish/lib/gf-client.jar in the client's classpath.
E.g., assuming the application classes are in /home/user1/myclasses and the main client class is acme.MyClient :
java -classpath $GLASSFISH_HOME/glassfish/lib/gf-client.jar:/home/user1/myclasses acme.MyClient
Note that the Java EE 6 API classes are automatically included by gf-client.jar so there is no need to explicitly add javaee.jar to the classpath. gf-client.jar refers to many other .jars from the GlassFish installation directory so it is best to refer to it from within the installation directory itself rather than copying it(and all the other .jars) to another location.
Note: gf-client.jar is located in $GLASSFISH_HOME/modules/gf-client.jar in GlassFish v3.
I had been using jmock with seam all these days, but its not sufficient to mock final/static/enums. So I tried working with JMockit. However everytime I run, I get NPE. Can't even debug, below is sample code
public class TestJmockit extends SeamTest {
#Mocked Dependency dependencyInCodeToTest;
CodeToTest bean = new CodeToTest();
#Test
public void testSaveSectionChangesJMockit() throws Exception {
new AbstractSeamTest.ComponentTest() {
#Override
protected void testComponents() throws Exception {
new NonStrictExpectations()
{
{
dependencyInCodeToTest.getLabel(); result = "Normal";
}
};
bean.execute();
}
}.run();
}
}
Actual Code..
package com.abc.action.account.information;
import com.abc.vo.account.ExternalAccountStatus;
import com.abc.vo.account.information.ExternalAccountStatusClosedInfo;
import com.abc.vo.account.information.ExternalAccountStatusInfo;
import mockit.Mocked;
import mockit.NonStrictExpectations;
import org.jboss.seam.mock.AbstractSeamTest;
import org.jboss.seam.mock.SeamTest;
import org.junit.Test;
public class ConsumerAccountInformationActionTestJmockit extends SeamTest {
#Mocked ExternalAccountStatus mockExternalAccountStatus;
#Mocked ExternalAccountStatusInfo mockExternalAccountStatusInfo;
// ConsumerAccountInformationAction bean = new ConsumerAccountInformationAction();
#Test
public void testSaveSectionChangesJMockit() throws Exception {
new AbstractSeamTest.ComponentTest() {
#Override
protected void testComponents() throws Exception {
new NonStrictExpectations()
{
{
mockExternalAccountStatus.getLabel(); result = "Normal";
mockExternalAccountStatusInfo.getClosedInfo(); result = new ExternalAccountStatusClosedInfo();
}
};
// bean.saveSectionChanges();
}
}.run();
}
}
If I put a breakpoint at class declaratiom (Public Class Consumer..), stepping over to next line causes NPE. If I take out the commented lines in the code, it fails at the first uncommented line.
I am using Java 1.6 and IntelliJ IDE. Wonder if it has to do with IDE configuration.
With TestNG I dont even get the stack trace, with JUnit I see the below..

General Objection: mocking is there to isolate you from external code,
especially from those coming from your server wendor ( like AbstractSeamtest ) - so
you do not have to initialize them or have server runing or whatever.
Treat mocked test as saved debug session. In your case you like to assure (I'm guessing), that method
bean.saveSectionChanges();
interacts correctly with seam infrastructure, or other collaborators. This is easily achieved by something like:
public static testProperInteraction(#Mocked final Collaborator collaborator) {
new Expectations() {
{
collaborator.doThis(with some parameters);
returns(something you like);
}
};
Bean bean = new Bean(collaborator);
assertSomething(bean.saveSessionChanges());
// nothing else shall be called
new FullVerifications() {
{
}
};
}
