Re: Using hivemind in servlets and pointing modules locations in general

[Achim Huegen]

The full service name is xxx.services.Counter since
you defined id="xxx.services" .
Try : registry.getService( "xxx.services.Counter", Counter.class );

Hi!
I have such problem:

In web-application I use HiveMindFilter as showen in hivemind documentation. there is xxx.services and xxx.servives.impl packages, where first contains interfaces

and second implementations. In web.inf i have such entry:
----------
<filter>
  <filter-name>HiveMindFilter</filter-name>
  <filter-class>org.apache.hivemind.servlet.HiveMindFilter</filter-class>
</filter>
<servlet>
  <servlet-name>App</servlet-name>
  <servlet-class>org.apache.tapestry.ApplicationServlet</servlet-class>
</servlet>
<filter-mapping>
  <filter-name>HiveMindFilter</filter-name>
  <servlet-name>App</servlet-name>
</filter-mapping>   ----------
in WEB-INF there is hivemodule.xml file which looks like that:
----------
<?xml version="1.0"?>
<module id="xxx.services" version="1.0.0" package="xxx.services">
   <service-point id="Counter" interface="Counter">
       <create-instance class="impl.CounterImpl" />
   </service-point>
</module>
----------

there is xxx.services.Couner.java and xxx.services.impl.CounterImpl.java files

and my code looks like:
----------
Registry registry= RegistryBuilder.constructDefaultRegistry();
Counter test= (Counter) registry.getService( "Counter", Counter.class );
----------

but I got such exceptions:

org.apache.hivemind.impl.RegistryInfrastructureImpl.getServicePoint(RegistryInfrastructureImpl.java:177) org.apache.hivemind.impl.RegistryInfrastructureImpl.getService(RegistryInfrastructureImpl.java:203)

org.apache.hivemind.impl.RegistryImpl.getService(RegistryImpl.java:68)

I think I miss something but really can't understand what.

Documentaion claims that filter will inicialize registry using WEB-INF/hivemodule.xml but I am not sure about it. Maybe module description is incorrect? I am stuck...
