Hi,
I am trying to get a stateful drools session to work, based on the current
servicemix 5.1.0 camel-drools example. Building and deploying the bundles /
features work fine. If I change the spring or blueprint to try to create a
stateful instance, I get a NPE exception thrown when I attempt to deploy the
bundle.
Is this broken, or am I missing some other configuration?
spring.xml snippet - changed type="stateless" to type="stateful"
<drools:ksession id="ksession1" type="stateful" name="ksession1"
kbase="kbase1" node="node1">
<drools:configuration />
</drools:ksession>
