Using hivemind in servlets and pointing modules locations in general
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...

No, the beta should be fine for this. Can you show us the code you use to
ask the registry for the Counter service and then subsequently call methods
on it? Show us the code you use to do it multiple times?

I am using 1.1beta2. Do I need to use 1.0? How stable beta2 is?

Having such simple service description as:
-----
<service-point id="Counter" interface="mediena.services.Counter">
<create-instance class="impl.CounterImpl" model="singleton"/>
</service-point>
-----
where Counter interface looks like this:
-----
int getCounter();
void increaseCounter( int value );
-----
and CounterImpl keeps counter value and logs each method I found that
every time
I ask registry for Counter service and call any method, registry creates
new instance of
Service. I call them from the same thread and even from the same
method... By default service
is sigleton, but even not defining model at all behaviour is still the same.

It can be placed in either location, using the HiveMindFilter.

The problem was in incorrect documentation.
As described here http://jakarta.apache.org/hivemind/filter.html
hivemodule.xml
must be placed in WEB-INF catalog, but later I found that it is required in
WEB-INF/classes/META-INF. I must say, that it is not very easy to find
something
in project documentation :(

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