Unable to find a Constructor?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
First of all, i'm very new to and very impressed with HiveMind. The
documentaion is clear and consise for the most part, so i've had some
good success with strict JavaBean properties style wiring with hive
modules. Now I am seeing some weird behavior when i add a no-args
constructor. I have something like the following:
[com.myapp.Service]
interface Service {
~ public void doStuff();
}
[com.myapp.access.AccessService]
class AccessService implements Service {
~ private Map myMap();
~ public void doStuff() { /*do something*/ }
~ public AccessService () {
~ myMap = new HashMap();
~ }
}
And in my hivemodule:
<module id="ioc" version="1.0.0">
~ <service-point id="AccessService" interface="com.myapp.Service">
~ <create-instance class="com.myapp.access.AccessService"/>
~ </service-point>
</module>
So when i do the following in my unit test:
~ registry.getService("ioc.AccessService", Service.class);
I see something like this:
org.apache.hivemind.ApplicationRuntimeException: Unable to construct
service ioc.AccessService: Unable to find a constructor for class
com.myapp.access.AccessService.
Any idea what i may be doing wrong? If there's a default constructor,
do i need to invoke-factory instead of create-instance?
Any input would be appreciated,
Jason

Man do i feel like an idiot... it was package level.
We're doing a little Spring/HiveMind comparison, and Spring could
create those instances with package level visibility.
Thanks!

Is your class defined public or like in the pasted code only with
