Hi Gary,
There are a number of missing links in your mail but I would guess that the NPE
is caused because in MLDocGenerator you have something like
try {
...
source = resolver.resolveURI(src);
}
catch(Exception ex) {
// ignore
}
}
public void recycle() {
resolver.release(source); // source == null here when exception
}
You have to propagate exception out of setup / generate.
Otherwise the container try to recycle and returns it to the component pool.
HTH, Alfred.

Subject: Enviroment missing in cron class?
I'm attempting something new for me in Cocoon 2.1.9 and would appreciate some
advice. Basically it's a cron class which not seem to have complete access to
the Cocoon environment.
The class extends ServiceableCronJob and runs this code to execute the pipeline
request:
resolver = (SourceResolver)
this.manager.lookup(SourceResolver.ROLE);
resolver.resolveURI(sb.toString());
This returns a result but does not include parts of the aggregation, it just
returns the result of the XSL transformation without data.
<map:part src="cocoon:/doc/db/{1}/params/{2}"/>
<map:part src="context:/appdata/data-query/{1}/{2}"/>
When I run the request with a browser the pipeline works ok. Another symptom
is a couple of exceptions:
org.apache.cocoon.ProcessingException: Unable to remove component from
automatic release: no environment available.
at
org.apache.cocoon.components.CocoonComponentManager.removeFromAutomaticRelease(CocoonComponentManager.java:489)
.
java.lang.NullPointerException
at org.apache.cocoon.environment.AbstractEnvironment.release(AbstractEnv
ironment.java:560)
at org.apache.cocoon.environment.wrapper.MutableEnvironmentFacade.releas
e(MutableEnvironmentFacade.java:313)
at com.envisn.nv.serialize.MLDocGenerator.recycle(MLDocGenerator.java:10
9)
Thanks for any suggestions,
gary
