IllegalArgumentException when configuring annotated services
perissf
I am trying to move a CometD web application from inherited services
to annotated services.
On GlassFish 3.1 I have this exception:
org.apache.catalina.LifecycleException:
java.lang.IllegalArgumentException: javax.servlet.ServletException:
com.sun.enterprise.container.common.spi.util.InjectionException: Error
creating managed object for class: class
org.jboss.weld.servlet.WeldListener
The basic web app has the following 2 classes taken from CometD
reference guides:
@Service("echoService")
public class EchoService {
@Session private ServerSession serverSession;
@Listener("/echo")
public void echo(ServerSession remote, Message message) {
remote.deliver(serverSession, message.getChannel(),
message.getData(), null);
}
}
public class ConfigurationServlet extends GenericServlet {
private final List<Object> services = new ArrayList<Object>();
private ServerAnnotationProcessor processor;
@Override
public void init() throws ServletException {
BayeuxServer bayeux = (BayeuxServer)
getServletContext().getAttribute(BayeuxServer.ATTRIBUTE);
processor = new ServerAnnotationProcessor(bayeux);
Object service = new EchoService();
processor.process(service);
services.add(service);
}
@Override
public void destroy() {
for (Object service : services) {
processor.deprocess(service);
}
}
@Override
public void service(ServletRequest req, ServletResponse res)
throws ServletException, IOException {
throw new UnsupportedOperationException("Not supported yet.");
}
}
and here is the web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<servlet>
<servlet-name>cometd</servlet-name>
<servlet-class>org.cometd.server.CometdServlet</servlet-class>

</servlet>
<servlet-mapping>
<servlet-name>cometd</servlet-name>
<url-pattern>/cometd/*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>cometconfiguration</servlet-name>
<servlet-class>servlets.ConfigurationServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
</web-app>
Any hints?
Thanks

The error says it cannot create an instance of WeldListener. Does not
seem related to CometD.

Finally, no matter how good the architecture and design are,
to deliver bug-free software with optimal performance and reliability,
the implementation technique must be flawless. Victoria Livschitz

somewhere else!
The code reported above, if deployed after restarting the application
server, works fine.
But when I try to inject the BayeuxServer instance into an EJB
Singleton called MySingleton, I get this exception when deploying:
javax.ejb.CreateException: Initialization failed for Singleton
MySingleton
Caused by: org.jboss.weld.exceptions.IllegalArgumentException:
WELD-001324 Argument bean must not be null
The other exception reported above is thrown after removing the
injection of BayeuxServer, and will always be thrown until I restart
the application server.
I then tried to inject the BayeuxServer in an ApplicationScoped bean,
but I got the following exception when deploying:
org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied
dependencies for type [BayeuxServer] with qualifiers [@Default] at
injection point [[field] @Inject private beans.MySingleton.bayeux]
So my question is: isn't it allowed to inject the BayeuxServer in one
of these Java EE 6 beans?
Thanks again

CDI is quite (over)complicated, and I spent only little time on
integrating CometD into CDI, so it's a new terrain that needs to be
explored.
Can you please file a bug at http://bugs.cometd.org so that we won't forget ?
If you find a solution, please keep us posted.
