Hi there,
I am using POJO Services to initialize different parts of an application that is deployed
in JBoss AS 5. I got the Service POJOs as such working just fine, but now I have a problem
making some of them accessible to "unmanaged" code that is deployed in the same
AS instance.
From what I could find online the only way to do that is to add a JNDI
binding aspect to the service POJO.
My first question would be, is that really the way to do it? Or is there a better way for
local client code to obtain a reference to the service?
I used the SimpleBean AOP example from the microcontainer documentation as a template but
when I deploy this in AS I get an error during server startup complaining that there is
already an AspectManager bean installed:

I removed the following section from the deployment descriptor:
| <bean name="AspectManager"
class="org.jboss.aop.AspectManager">
| <constructor factoryClass="org.jboss.aop.AspectManager"
| factoryMethod="instance" />
| </bean>
|
But that yields a different error on server startup:

I read that org.jboss.aop.deployers.AspectManagerJDK5 is what has to be used with AS 5.
Any help on how to do service lookup differently or how to solve the above problem is
greatly appreciated!
Thanks
Ralf
