[JBoss Remoting Users] - Re: is JBoss remoting good choice for me ?

I think you're on the right track.

That's a matter of configuration, and how you do the configuration depends on the transport you're using. In the socket transport, which is the most commonly used transport, the parameter "maxPoolSize" determines the maximum number of worker threads, where each worker thread services one invocation at a time. The default value is "300", so that you could have up to 300 clients connected simultaneously.

The Remoting code is thread safe. It's up to you to make your ServerInvocationHandler thread safe.

That looks reasonable. Note that, in addition to the parameter, you can pass an entire map of objects by calling

in org.jboss.remoting.Client. In the ServerInvocationHandler the map can be retrieved with org.jboss.remoting.InvocationRequest.getRequestPayload().
Good luck.

[EJB 3.0 Users] - Session EJB and MDB Configuration
by kyle.bober
JBoss 5.1.0.GA
I am attempting to configure my Stateless MDB via the instrcutions provided at the following link : http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/...
Here is my mydoamin-aop.xml :
| <?xml version="1.0" encoding="UTF-8"?>
| <aop xmlns="urn:jboss:aop-beans:1.0">
| <domain name="Strictly Pooled Message Driven Bean" extends="Message Driven Bean" inheritBindings="true">
| <annotation expr="!class((a)org.jboss.ejb3.annotation.Pool)">
| @org.jboss.ejb3.annotation.Pool (value="StrictMaxPool", maxSize=2, timeout=10000)
| </annotation>
| </domain>
| </aop>
|
Here is my jboss.xml :
| <?xml version="1.0" encoding="utf-8"?>
| <jboss xmlns:xs="http://www.jboss.org/j2ee/schema"

Both of these are included in my ejbname-ejb.jar file in the META-INF folder. My EJB Jar file is included in my EAR file which I can deploy to JBoss. When I start up the application server I receive the following exception:

[Installation, Configuration & Deployment] - Starting javax.ejb.timer causes java.lang.IllegalStateExcept
by lvonk2000
Hi,
We are migrating from jboss 4.2.3 ot jboss 5.1.0 jdk6. In 4.2.3 we had a @Service bean that started a timer in the start() method. In jboss 5.1.0 we get this exception when the start() method is called:

Is this intentional in jboss 5.1.0? I know it is against the spec for EJB's constuction methods, but I thought for the @Service is allowed (or at least not against the spec)?
Are there any other ways to use the ResourceMonitorServiceBean to start the timers? Or do I need to create a WAR file that calls a method on the ResourceMonitorServiceBean to start the timers?
Thanks in advance
