[jboss-user] [Clustering/JBoss] - Caching, hybernate and using enums => no go
Hi,
We have JBoss AS 5.1.0 and use hibernate to store our session beans in MySQL DB. Also pojo
caching is used to make the objects available throughout the cluster.
For both hibernate and caching we use annotations.
@Replicable for classes that need to go into cache and
@Entity for objects that need to be stored using hibernate.
We compile everything and the @Replicable classes with aopc.
If we deploy the created jar file and start JBoss we get a java.lang.VerifyError.
This error originates from a switch statement that is using an enum to switch.
The enum is defined in a @Replicable class called HelperClass
the switch method is defined in the bean called Request
Disabling hibernate OR @Replicable OR both there is no problem starting JBoss.
I can not imagine that this is an unknown problem, one of you probably must have had the
same problem. If so what was the solution?
Kind regards,
Werner van Mook
