So, I'd like to have a ruleset that returns true or false. The way I set that
up in one of the version 5 candidate releases is to use a Boolean global and
use drools.getWorkingMemory().setGlobal(result, new Boolean(false)) to
change the value of the global. I could then access the updated value

I'm using various KnowledgeBase objects in a J2EE environment, using JBoss
4.2 as the application server. Currently, I keep a list of KnowledgeBase
objects in a stateless session bean. The thought being that to keep the
application scalable, we don't want contention around rule sessions.
In the M5 release, I could use a Boolean global as an Out type parameter and
changes I made to the global would be maintained in the results. In CR1, I
use the CommandFactory to add the global with out set to true, and I get
back the initial value of the Boolean, not the updated value.

Thanks for the response. I used the eclipse workbench (5.0.0.CR1) to create
the runtime jars, putting the jars into my JBoss server's lib directory. The
jars don't have the version# on them (ie drools-compiler.jar).
Looking in guvnor.war, I see drools-compiler-5.0.0.CR1.jar. These
I built a rule package in Guvnor and downloaded the binary. When I use:
builder.add(ResourceFactory.newInputStreamResource(inStream),
ResourceType.PKG);
I get a NullPointerException. But, if I use Guvnor's view source, copy the
source to a file, and use:

Yes, the exception occurs on both the filesystem and Guvnor, and it happens

It is my intention to build all rule packages in Guvnor (or some other
process) before deploying the packages to a production environment. I see
that I can use a KnowledgeBuilder with a PKG type resource to create
KnowledgePackages, and then initialize a KnowledgeBase with the
KnowledgePackages.
Is there any recommended Best Practice for instantiating and accessing a

One use case for this type of session is it will act as a Complex Event

Charlie,
I'm not sure why your function doesn't compile as it looks fine to me. Do
you have any other details about the message you're getting from the

In any case, you may want to consider solving the problem a different way.
In general, you should try to avoid eval statements

Unfortunately, we can't use the results of the update in the when clause of
other rules if we put it in a global.

You'd probablt also have to prevent the Close Facts rule from firing
when there's just no ChargeTrackers in working memory, too.
Give that a try.
