[Clustering/JBoss] - HAJMS Failover problem running within a Veritas cluster
by sheckler
Hi,
let me try to describe the architecture on the customers site and the observed behavior, which was categorized as an error by the customer.
An JBoss cluster is running within a Veritas cluster on Solaris (JBoss Version 3.2.8SP1)
There are two zones, each containing 1 application server and 1 oracle server. In zone A the HAJMS Master and the oracle server for the HAJMS is running. In zone B the second jboss cluster node, which is not HAJMS Master, is running and the standby database.
Now the zone A is killed and the following happens on the second jboss cluster node.:
- HAJMS Failover of running JMS Clients like MDBs etc. -> ok
- Ping database failure of connection pool -> ok
- a new cluster view is detected with only one member -> ok
- the node is not becoming HAJMS master -> not ok
After 1 minute the standby db is available and the errors of the connection pool stop
- The node is never becoming HAJMS master and has to be restarted, as there is no more JMS available.
This means downtime and manuel action.
Obviously the JMS master change does not work, when at the same time the database is not available.
My hope is, that some parametrization of JMS can avoid this situation. Has anyone an idea?

[JBossWS] - @WebFault and @XmlType issues for Exception classes
by yogeshkb
Hi Team,
I have many webservices with operations throwing a common exception (eg., SomeException) across all the services
I tried to annotate the SomeException class using various approaches but failed to generate the client stubs with a common target namespace different from the targetnamespace of the webservice itself.
Approach 1:
Used @XmlType(namespace="common.targetnamespace") in the SomeException class
Approach 2:
Used @WebFault(targetNamespace="common.targetnamespace")
In both the above approaches, the wsconsume generated a separate stub for SomeException class for each webservice in the same targetnamespace of the webservice and not on the specified common.targetnamespace.
My requirement is to generate a single SomeException client stub in the common.targetnamespace.
Pls let me know whether this is a bug or suggest some workarounds.
Regards,
Yogesh
