Is anyone already working on moving this to Axon 3?

Now we have a groovy based auto trader, we want to have a button to start auto trading with the available users/companies etc.

In the architecture wiki document you state that:

One important part for the users of the system is that the username's must be unique. When receiving a command to create a new user, we first check against a special collection to see if the username is still available. After validation we actually create the user.

However, I cannot find that check in the code, and I can easily create a test that attempt to create two users with the same username.

    @Test
    public void testHandleCreateUserTwice() throws Exception {
        UserId aggregateIdentifier = new UserId();

        UserEntry userEntry = new UserEntry();
        userEntry.setUsername("buyer1");
        userEntry.setIdentifier(aggregateIdentifier.toString());
        userEntry.setName("Buyer One");
        Mockito.when(userQueryRepository.findByUsername("buyer1")).thenReturn(userEntry);

        fixture.given(new UserCreatedEvent(aggregateIdentifier, "Buyer 1", "buyer1", DigestUtils.sha1("buyer1")))
                .when(new CreateUserCommand(aggregateIdentifier, "Buyer 1", "buyer1", "buyer1"))
                .expectEvents();
    }

The test gives:

For Axon Framework users it's beneficial to see an Axon Framework application which follows (what we regard) the best practices of such an application.
This work will thus entail stuff like:

• Updating most/all versions to the latest, especially the framework version.
• Incorporate Kotlin for the core-api module, as this provides a more concise solution for immutable objects.
• Introduce @QueryHandler annotated functions to Query Handling Components.
• Move the @CommandHandler annotations to the Aggregates i.o. a separate Command Handling Component.
• Use the @EventSourcingHandler annotation in Aggregates i.o. the @EventHandler annotation.
• Steam line configuration classes by using several of the automatically created beans through a Spring Boot Axon application.
• An overall style code update of all the classes.
• And very likely, a whole bunch of other adjustments as well.

1. Log in as buyer1
2. Go to Companies
3. Go to BP
4. Click Buy
5. Enter 1000 for price to trade and amount of items to trade
6. Click place order
7. Site redirects to company page, but no orders display.
8. An exception is logged...here is the log.

In the past jetty integration with maven was a lot easier than Tomcat. Since we use tomcat for most of our projects, we prefer to use tomcat. We are going to move to Tomcat 8 for their web socket support.

I downloaded the axon-trader demo today. When i run mvn tomcat7:run in the main folder, i get this error message:

After logging in, I'm redirected to http://localhost:8080/favicon.ico which shows

HTTP ERROR 404

Problem accessing /favicon.ico. Reason:

NOT_FOUND

Manually navigating back to the home page works, and I'm logged in, but it's a disconcerting error.

Hi!

I would like to clarify some points of using repositories and aggregates.
What I see from javadoc for the execute and handle methods:

* Note that the use of this method is not recommended as the wrapped aggregate instance is not meant to be
* exposed. Relying on this method is commonly a sign of design smell.

However, I see them used in this sample project, for instance in CompanyCommandHandler, line 46:

Aggregate<Company> company = repository.load(command.getCompanyId().toString());

company.execute(aggregateRoot -> aggregateRoot.addOrderBook(command.getOrderBookId()));

So is this ok to to use them in such way?

I deploy sample into tomcat, it throws error

How can you change the current database hsqlDb to Mysql database? Thank you for your advice.

Cloudfoundry does not support free hosting anymore, therefore we remove the classes needed for cloud foundry.

Is there a default login name/password for the sample app?

I am getting this error. I have tried to run it multiple times and after reading the documentation too.
I am missing something ? i am not able to see any pages at 8080. Please comment if you are able to run or any of the branches are working.

I downloaded the project . went into Axon-trader folder and run mvn tomcat7:run

below lines should be removed:
long available = obtainCurrentAvailableItems(event.getOrderBookIdentifier());
availableItems.put(event.getOrderBookIdentifier(), available - event.getAmountOfConfirmedItems());

Within the sample the idea is that a company can have multiple order books. At the moment this is not really the case. The order book is correlated to the company, they share the same identifier.

We want to refactor this to a solution where the relation ship between an order book and a company is taken care of within the company context.

Could these be updated to use the latest release of your Axon Framework and Spring/Spring Boot?

when start with mvn tomcat7:run, the hsql is used. How can I switch to mongo db?
