Gunnar,
While WF doesn't include infinispan-cdi integration, you can inject
Infinispan caches defined within the Infinispan subsystem as standard
EE resources via the their JNDI bindings. This approach has the
advantage of container-managed lifecycle of the cache, even when
referenced by multiple deployments.
e.g.
@Resource(lookup = "java:jboss/infinispan/cache/foo/bar")
private Cache<?, ?> cache; // References the "bar" cache of the "foo"
cache container
or
@Resource(lookup = "java:jboss/infinispan/cache/foo/default")
private Cache<?, ?> cache; // References the default cache of the
"foo" cache container
Unfortunately, a long standing weld integration bug prevents @Resource
lookups from working correctly when the containing class is
instrumented by CDI. To workaround this, move the JNDI lookup to a
<resource-ref/> or <resource-env-ref/> in your deployment descriptor
and reference your cache resource via its reference name.
e.g.
<resource-env-ref>
<resource-env-ref-name>my-cache<resource-env-ref-name>
<resource-env-ref-type>org.infinispan.Cache<resource-env-ref-type>
<lookup-name>java:jboss/infinispan/cache/foo/bar</lookup-name>
</resource-env-ref>
@Resource(name = "my-cache")
private Cache<?, ?> cache;
