May be I do something wrong.
I wrote in the server.xml in
<GlobalNamingResources>
<Resource name="bean/HivemindRegistry" auth="Container"
type="org.apache.hivemind.Registry"
description="Global Hivemind registry"
factory="com.intersolved.hawk.web.HiveMindFactory"
/>
</GlobalNamingResources>
In the log file I see that my factory is invoked. I can see my registry
via jconcole (because tomcat registries it in the JMX)
But in the filter of the web application I can not get it
Context initCtx = new InitialContext();
Context javaCtx = (Context)
initCtx.lookup("java:comp/env");
registry = (Registry)
javaCtx.lookup("bean/HivemindRegistry");
I get NameNotFound exception.
By the way how can I stop this registry (constructed in such way) when
tomcat will be shutdown.
Best Regards,
Dmitry

I think, the canonical way to do this in Tomcat, is defining a global
Resource in Tomcat with a custom ResourceFactory which sets up your Registry
using
RegistryBuilder. In server.xml that would look like
<Resource name="HivemindRegistry" auth="Container"
type="org.apache.hivemind.Registry"
description="the HivemindRegistry"
factory="some.package.MyRegistryFactory" />
Note, that afaik Webapps cannot access global JNDI-Ressources directly.
You'll have to map it into the local namespace (java:comp/env) via
resource-env-ref / ResourceLink in your web.xml / context.xml.

Subject: Re: Hivemind+Tomcat
I tried to put registry to the JNDI int the LifecycleListener
Context initCtx = new InitialContext();
initCtx.bind(HIVEMIND_REGISTRY_KEY,registry);
but I can not access to it at any web aaplication.
Code generate unboun exception
Context initCtx = new InitialContext();
initCtx.lookup(HIVEMIND_REGISTRY_KEY);

Hi Dmitry,
the registry itself is threadsafe. you only need to take care when
constructing it.
that means you can either run it as a singleton or add it to a jndi
context.
these are probably the simpliest solutions, i think.
btw. does someone know about any performance issues
when running a single registry in a heavily mutlithreaded
environment?

Hi
Hivemind has filter which can be set for web application
and can be used for working with registry.
But I want to setup Registry for all application which
will be started
under Tomcat. It is possible to write LifecycleListener for Tomcat
and init/shutdown Registry there. But how to access that registry
in the web applications. I did not find any solutions.
May be somebody
confront with this problem?

Dmitry
