Can't test drools-insurance with BRMS 4.0.7
by Fred Machin
Hi,
I can't get drools-insurance to work with the latest Drools BRMS 4.0.7. I
followed the installation instructions in the drools doc, got the
drools-insurance from SVN (trunk), installed the repository in BRMS, but
when I test it, i get the following error :

Re: [rules-users] Can't test drools-insurance with BRMS 4.0.7
by BrycePC
Hi,
I am currently getting the same error when trying to run insuranceDemo,
using the latest versions of components. Have you had any success since in
getting this working? It looks to me like the drools engine can't read the
repository built within BRMS, from the imported repository_export.xml...?
Regards,
Bryce

MSB Example
by Steven Núñez
Greetings Drools Users,
Does anyone have, or know of, an example of using drools, fronted by a MDB?
A stateful example would be fantastic, but any example welcome. I'm under a
very tight deadline, and would like to leverage anything that's already been
done to speed things up. Production quality not required; I just need to
prove it will work.
Regards,
- Steve

The Eclipse JDT Core jar is not in the classpath
by Christopher.Mathrusse＠sybase.com
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. I
would prefer it if there was some way of setting this property without
having to use the JDT libraries.
I saw that I can provide system properties to make Drools aware of the req
uested 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?
Thanks very much for the help.
