ComponentLoader problem
Hi,
I am using t-2.2, and am trying to use some fulcrum based services I have
written. I am having a problem because the ComponentLoader which is meant to
load fulcrum services defined in the fulcrum properties file, won't load
anything.
When I try to use the service, the TurbineServiceBroker returns an "unknown
service" error.
The component loader also wont log because it requires a log4j appender, and
log4j is not used this way in t2.2.
I dont think it is even finding my Fulcrum.properties file. But without
logging this is difficult to determine.
The component loader is defined in my tr-props as:
${webappRoot}/WEB-INF/conf/Fulcrum.properties
Has anybody managed to use a fulcrum style service with 2.2 sucessfully?
Please help!
Gareth

Again, I haven't actually tried this stuff so these
suggestions are educated guesses...

I think that's correct. Something like this:
import org.apache.fulcrum.Fulcrum;
import org.apache.fulcrum.intake.IntakeService;
...
return (IntakeService)Fulcrum
.getInstance().getService(IntakeService.SERVICE_NAME);

My guess here is that the Fulcrum.properties file might
have different logging levels set. Or perhaps that there
is something about the path to the log file that's missing.

Here is a stack trace from turbine.log:
Exception: org.apache.turbine.util.TurbineException: Instantiation failed
for com.majorband.project.tool.IntakeTool: ServiceBroker: Unknown Service
'IntakeService' requested
Stack Trace follows:
org.apache.fulcrum.InstantiationException: ServiceBroker: Unknown Service
'IntakeService' requested
at org.apache.fulcrum.BaseServiceBroker.getServiceInstance(Unknown Source)
at org.apache.fulcrum.BaseServiceBroker.getService(Unknown Source)
at
com.majorband.project.services.intake.ProjectIntake.getService(ProjectIntake
.java:253)
I have created an intake like pull tool of my own, and from this pool tool,
I am calling the service I have created (which worked succesfully in t3).
At the moment in my code I am getting an instance of the service by:
return (IntakeService)TurbineServices
.getInstance().getService(IntakeService.SERVICE_NAME);
Should I be using the fulcrum.Fulcrum class instead?
None of the services in my Fulcrum properties file appear in the services
initialisation section of the turbine.log.
Any help would be greatly appreciated.

I haven't actually tried to use fulcrum services from T2 yet, but
I think the usual access through the services static facade methods
should work. Either that, or through the Fulcrum class's static
methods. I have several other things I need to get to first, but
I'll try to take a look this afternoon unless you figure it out
before I get to it.

Ok.
I know now (from debugging the ComponentLoader) that it is working perfectly
and loading the component.
So I must be doing something wrong.
I assumed that services within the fulcrum.properties file would just be
exposed as normal services, but clearly this is not correct.
How should I use fulcrum services within my code???? (in t-2.2)
