Comet on Tomcat 7 is not recommended. Tomcat 7 comet support is
extremely buggy, especially with NIO connector and/or under load.

At the very least, make sure you are using the very latest tomcat
release. Even so - my experience recommends you use Jetty for this
application.

It looks like you are using the APR. I wouldn't be surprised if it
suffers from the same problems are NIO.

Well, you did not show us your code, so we can't help you.

You're mixing the inherited style with the annotated style, not
recommended. Choose one only. See
http://docs.cometd.org/reference/#java_server_services.

Should be:

getBayeux().getChannel("/message/demo").publish(getServerSession(),

"Hello", null);

Thanks.

I use  annotated services , with jetty7 and springmvc3.1。

my web.xml code：

<servlet>

        <!-- <servlet-class>org.cometd.server.CometdServlet</servlet-class> -->

        <servlet-name>cometd</servlet-name>

        <url-pattern>/cometd/*</url-pattern>

}

}

run the web application, the EchoService not works. My own log and "system.out" is not print.

I use jetty7 and the spring3.1mvc.

I see my spring config with cometD is error, bug I not found the error.

I'm so sorry, I distrub you. I like the cometD. I hope you can help me. 

Run cometD service on the jetty7 and spring3.1mvc.

In addition, I hope that the official website provide springmvc3.x and  annotated services examples code,

In this way, to make learming easier. Will have a lot of people use.

Thank very much.

Hi,

You do not really want to have both a @Listener and a @Subscriber for
the same channel.
Use either, not both.

Where is your client code ?

[古木天琪]

Thanks,  Bordet .

I seem to have run successfully.

I removed the spring-config.xml configuration.
But the inexplicable emergence of: sessionRemoved operation. 
I would now like to to use cometD in springmvc controller inside, how can I use it.

Here is my code:
EchoService code:

@Service

public class EchoService {

@Inject

private BayeuxServer bayeux;

@Session

private ServerSession serverSession;

@PostConstruct

void init() {

System.out.println("Echo Service Initialized!!!");

bayeux.addListener(new BayeuxServer.SessionListener() {

@Override

public void sessionRemoved(ServerSession session, boolean timeout) {

String user = (String) session.getAttribute("user");

session.deliver(serverSession, "/message/demo", user + "disconnected !", null);

session.removeAttribute("user");

}

@Override

public void sessionAdded(ServerSession session) {

session.setAttribute("user", bayeux.getContext().getHttpSessionAttribute("user"));

String user = (String) session.getAttribute("user");

session.deliver(serverSession, "/message/demo", user + "disconnected !", null);

}

});

}

@Configure("/**")

void configure(ConfigurableServerChannel channel) {

channel.addAuthorizer(GrantAuthorizer.GRANT_NONE);

}

@Configure({"/message/**", "/service/**"})

void configureMsg(ConfigurableServerChannel channel) {

channel.addAuthorizer(GrantAuthorizer.GRANT_ALL);

}

@Listener("/service/message")

void deliverReceive(ServerSession remote, ServerMessage.Mutable message){

@SuppressWarnings("unchecked")

Map<String, String> data = (Map<String, String>) message.getData();

String userName = (String) remote.getAttribute("user");

remote.deliver(serverSession, data.get("room"), userName + " 说:" +data.get("msg"), null);

}

}

web.xml code:

    </servlet-mapping>

I used the above code, run successfully cometD. You think is right?
1.  I would now like to to use cometD in springmvc controller inside, how can I use it?

For example: I query the database and return some data to the page in this controller.

@Controller

@RequestMapping(value="/user")

public class UserController {

     @RequestMapping(value="/test", method={RequestMethod.GET})

public String test(Model model){

//coding ....use cometD EchoService?

                //EchoService.publishReceive(? , ?);  //how to write this parameter

}

}

2.  I‘s provided using lombok.jar use in EchoService, the @Log4j is not print log. is bug?

Thank you very much for your help

Not sure why you removed the Spring config. If you keep it, you can
inject the EchoService into this controller, which I think it's the
best way to go.

Not a CometD bug for sure, we do not use @Log4j annotations.

[古木天琪]

this is my Spring config:

<!-- Spring CometD config -->

    <bean id="nonLazyService" class="com.aosatech.j2ee.nms.service.nonLazyService" />

    <bean id="bayeux" class="org.cometd.server.BayeuxServerImpl" init-method="start" destroy-method="stop">

        <property name="options">

            <map>

                <entry key="logLevel" value="3" />

                <entry key="timeout" value="15000" />

            </map>

        </property>

    </bean>

    <bean id="echoService" class="com.aosatech.j2ee.nms.service.EchoService">

        <constructor-arg><ref local="bayeux" /></constructor-arg>

        <constructor-arg><ref local="nonLazyService" /></constructor-arg>

    </bean>

    <bean class="org.springframework.web.context.support.ServletContextAttributeExporter">

   <property name="attributes">

    <map>

    <entry key="org.cometd.bayeux">

    <ref local="bayeux" />                

    </entry>            

    </map>        

   </property>    

    </bean>

I reserve Spring conf, I do not know nonLazyService what the use.
So, how to the write the Spring Controller?

Hi,

I am not that familiar with Spring MVC, so should perhaps asks in Spring forums.

I think you can just @AutoWire your EchoService in your Spring
controller, but I never tried.

[古木天琪]

Thanks

I will then try to run in springmvc with cometD .

I will tell you my test results, and then help others.

One day, to obtain I think I could create a cometD the Chinese community. 
Help more people use cometD.

If I were in the other servlet use the EchoService the then serverSession how to obtain it？

Not sure I understand, however: you have the problem of obtaining the
EchoService reference in another servlet.

You have several solutions for this:

A) use Spring injection
B) store the EchoService instance in the ServletContext as an
attribute, and retrieve it where you need it.

There are others, but these two are the ones I recommend.

Solution A is if you're using annotated services with Spring.
Solution B is if you're using inherited services.

Have you tried to @Autowire the EchoService in Spring MVC controller ?

[古木天琪]

I remove spring config ,use annotated services at EchoService

@Named

@Singleton

@Lazy

I use @Autowire the EchoService in Spring mvc controller.

bug have a error:

Your error is below:

It is all written above, you have a Spring configuration problem.

Really, you can't expect us to help without knowing your exact code
and configuration.
Please try to spend a bit more time understanding Spring and how it works...
None of your problems is a CometD problem, so far.

The first Google hit for "spring mvc inject bean" is:
http://stackoverflow.com/questions/3735762/how-do-you-inject-a-bean-into-a-controller-class,
which like I said, allows you to autowire the EchoService.

Figure this out, and you'll see that CometD will work.

[古木天琪]

if I use the Spring config,

hava a this error:

Error creating bean with name 'echoService' defined in class path resource [spring-config.xml]: Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

this is my spring config code:

<!-- Spring CometD config -->

    <bean id="nonLazyService" class="com.aosatech.j2ee.nms.service.nonLazyService" />

    <bean id="bayeux" class="org.cometd.server.BayeuxServerImpl" init-method="start" destroy-method="stop">

The problem is written clearly above, in the error message.
Please google for it.
