After analysis I found that in *wmq.jmsra.rar\META-INF\ra.xml* file there is reconnectionRetryCount = 5 and reconnectionRetryInterval = 300000 that is causing the server to auto reconnect to MQ every 5 mins.
Using RAR software, I extracted the ra.xml file and modified those properties. Again packaged to .rar file.
After the deployment of .rar file and restarting the server the deployment of .rar fails due to the below errors.
Please let me know how to resolve this.

[JBoss AS 7 Development] - jboss as7 clustering - need help with setting up maven and finding documentation

Hi.
I'm trying to set up a new demo project to do some jboss clustering PoC based on the latest and greatest (as 7.1.1 right now).
I basically need 3 things (that i know of) in my build - a dependency on the j2ee6 spec, a dependency on the jboss ejb3 ext api, and some dependency to allow me to write jboss services - because they seem to be the only way to do clustered singletons? (see https://community.jboss.org/message/646537#646537 https://community.jboss.org/message/646537)
for the j2ee specs, i already know i can do this in my parent pom:
this will allow me to add dependencies on various j2ee6 specs with the exact versions taken from the above pom.
is there a similar aggregation for jboss extensions?
for the ejb-ext-api, for example, i know i can do this:
but thats just a single jar, and i have no idea what the proper dependency is for the service API (s ?).
also, how do i keep these consistent with each other and with the particular jboss version i plan to deploy on?
for example, jboss-javaee-6.0:3.0.1 is under jboss-parent:0 while jboss-ejb3-ext-api:2.0.0 is under jboss-parent:7 - which might cause issues?
how do i tie the spec versions im building against to the spec versions supported by the jboss version im to deploy on?
and a last question - where do i go to to learn how to write jboss services?
thanks in advance for any pointers,
Radai.

Hi All,
I have implemented a statlessBean with Timer service. The timer is getting created without any issue, but when the @Timeout method is getting invoked I am getting the below excetion:

[Clustering Development] - Session Scope (war project without EJB) bean does not replicate but @Stateful (Ear project with EJB)
by Mahadev Sawale

Hi,
I have a seam web application(war project) with one session scoped bean:
@Name("crudAction")
@Scope(ScopeType.SESSION)
public class CrudActionBean implements Serializable{
private String msg; //with getter and setter methods
public String crudAction(){
msg= "Content to be displayed on crudAction page after this action"; // this will be displyed in <h:outputText../> on crudAction page.
return "/crudAction.xhtml";
}
}
web.xml has <distributable/> tag defined.
components.xml has distributable="true" defined in <core:init.../> tag.
I am using Seam 2.2, Jboss 5.1 server and JDK 1.6 and Windows XP OS.
After killing jboss of node1, if I try to reload page or do some action, I get following error message on jboss console of node2:
And does not replicate session.
+ClassNotFoundException occurred unmarshalling value java.lang.ClassNotFoundException: org.domain.seamdemo.session.CrudAction+
Detailed stack trace has been attached here with this post.
But replication works successfully, if I try above by creating Ear project and modifying the bean to SFSB like:
@Stateful
@Name("crudAction")
@Scope(ScopeType.SESSION)
@Clustered
public class CrudActionBean implements CrudAction,Serializable{ "same code as above"} //CrudAction is @Local interface.
The value of msg variable were displyed even after realoding page.
Can someone please help me for the above.
Let me know if additional information is needed.
Thanks.
