Made the changes specified in the userguide, but now it doesn’t send anything. I’m using the following:

MessageBuilder.createMessage().toSubject("Items").signalling().with("SerialNumber", "Test").noErrorHandling().sendNowWith(bus);

It still seems to be set up just fine since the in.erraiBus servlet is created and the client long polls it, but the code above doesn’t seem to send anything. I’m using the following way to make it for the DefaultBlockingServlet:

<listener-class>org.jboss.errai.bus.server.ErraiServletConfig</listener-class>

</listener>

Should I be using that? I figure it shouldn’t affect the client any though unless the servlet is incorrectly set up as a consequence, which it doesn’t seem to be since they communicate just fine for the initial setup. What should I look at to see why it’s not sending?

You should be aware we have made changes and are retiring the use of the CommandMessage API. Be sure to read the documentation in the userguide/src/main/docbook/en/master.xml file. You can use: mvn jdocbook:generate to create an HTML file from the userguide/ directory.

Hi Kevin, the compilation problems should be fixed already.

Yes, I am using trunk. Is there a more stable branch/version I should be using? I had updated again hoping it was just something with the time I checked out and then ran into the problems Heiko Braun ran into compiling it.

What version of ErraiBus are you using? Are you getting it from trunk?

DefaultBlockingServlet seems to have the same effect.

I will check into this. We're still working on getting the AIO stuff sorted, and I wouldn't consider the Tomcat or JBoss adapters to be production ready. You're best to use the DefaultBlockingServlet -- which will provide adequate performance for development while we get the AIO adapters squared away over the next few days.

I’m having trouble getting a message to go through using ErraiBus. I’m using this on the client side:

CommandMessage msg = (CommandMessage) CommandMessage.create().toSubject("Items").set("SerialNumber", serialInput.getValue());

bus.conversationWith(msg, new MessageCallback() {

@Override

public void callback(Message message) {

//throw new UnsupportedOperationException("Not supported yet.");

Item item = message.get(Item.class, "Item");

MessageBox.alert("Errai", item.getSerialNumber().toString(), null);

}

});

With this on the server side:

@Service("Items")

public class Items implements MessageCallback {

private MessageBus bus;

@Inject

public Items(MessageBus bus) {

this.bus = bus;

System.out.println("Got a bus...");

}

@Override

public void callback(Message message) {

//throw new UnsupportedOperationException("Not supported yet.");

System.out.println("Incoming message...");

Long serialNum = message.get(Long.class, "SerialNumber");

System.out.println(serialNum);

Item item = new Item();

item.setSerialNumber(serialNum);

ConversationMessage.create(message).set("Item",item).sendNowWith(bus);

}

However, all it seems to send is:

{"CommandType":"RemoteSubscribe","ToSubject":"ServerBus","Subject":"temp:Conversation:2","PriorityProcessing":"1"}

I don’t see where it actually sends my body or the subject that I fill out in my message. Nothing also gets to the Service class. Am I doing something wrong? I have Tomcat running NIO and everything else seems set up correctly. It will keep a GET connection open and do the POST of the JSON above, but nowhere does it seem to send what I want it to. I also seem to be getting these occasionally, usually on some of the first requests to in.erraiBus:

java.lang.NullPointerException

Can anyone point me at what I’m missing?
