Hi Mark,

Thanks for the reply. I created a packagebuilder.conf file that simply had name/value pairs in it as follows:

drools.dialect.java.compiler=JANINO

and I placed into one of each of the following locations:

WEB-INF
WEB-INF/classes
META-INF

I tried each one, one after the other but I still receive the same error message at application startup. Do I have the entries correct? Should I be placing this somewhere else? Is there something that I am still overlooking?

Thanks for the help...

Chris

Subject	Re: [rules-users] The Eclipse JDT Core jar is not in the classpath

I'm using JBoss Rules 4.01 with Spring 2.5 and I'm utilizing the JSR-94 interfaces provided by Spring Modules. When deploying my application I receive the error:

The Eclipse JDT Core jar is not in the classpath

I've searched through the postings and found that setting the compiler to drools.dialect.java.compiler should resolve the issue but I am having trouble figuring out where to set this property on the JSR_94 interfaces. I've tried passing a Map into

ruleAdministrator.getLocalRuleExecutionSetProvider(providerProperties);

with the following specified in my Spring configuration:
<prop key="drools.dialect.java.compiler">JANINO</prop>

but I believe the initialization occurs long before this point.

I've also tried dropping into the applications WEB-INF/lib directory a copy of the jasper-compiler-jdt.jar into the WEB-INF/lib directory, which should satisfy the dependency, but it didn't seem to resolve the issue.
Either that's the wrong classpath location, or that jasper compiler isn't hte same thing, try the jdt.jar supplied with drools.
I would prefer it if there was some way of setting this property without having to use the JDT libraries.
This should be possible, have you tried adding a packagebuilder.conf to tbe WEB-INF directory as the propperties loader checks for one of those first.

I saw that I can provide system properties to make Drools aware of the requested compiler setting but this is not really an option as I am running inside of a J2EE container and I am unable to modify the settings that are provided to the application server. Is there a default location in the classpath that Drools looks for a properties file that I can specify these values? Or better still, is there a way that I can supplied them to the JSR-94 interfaces to ensure proper initialization?
no and it is for this reason that I tell people to stay away from the abomination that is JSR94.

Thanks very much for the help.

Chris
