Hi,

I have two bundles:
activiti-osgi-karaf that starts process engine, listen for JavaDelegates (ref. Activiti In Action).
activiti-osgi-process: contains process .bpmn20.xml files and java delegates

I am using BluePrintELResolver to resolve OSGi reference of JavaDelegates using the syntax:
<serviceTask id="foo" activiti:delegateExpression=${javaDelegateService} />

The above works (as explained in Activiti In Action book)

I would like to define a bean (not an OSGi service) in the activiti-osgi-process blueprint context xml file:
  <bean id="greetingsBean"
      class="com.dell.pg.merlin.workflow.applyprofile.GreetingsBean" />


I would like to be able to call a particular method on this bean.
In other words, I would want the following to work in the process Service Task definition:
activiti:expression=#{greetingsBean.getFoo()}

However, I am getting error that greetingsBean property could not be resolved.

Do I need to chain another ELResolver to resolve beans in the blueprint context? BlueprintELResolver seems to be resolving only JavaDelegates.

Any help is greatly appreciated.

thanks

In the activiti config, you can define "beans" which are exposed in expressions. This is a map of beans on the config (http://activiti.org/userguide/index.html#exposingConfigurationBeans). If you're in spring-context, all spring-beans are exposed UNLESS you define any value in the ProcessEngineCOnfiguration.beans property.
