Hi Drools Users,
I'm new member, Mujoko.
I got issue regarding my rules. Several times got exception when trying to
create KnowledgeSession. I used drools-core 5.3.0.Final and drools-compiler
5.3.0.Final.

Building Guvnor - Required Java version?
by Stephen Masters
Hi folks,
Having grabbed Guvnor from github and switched to the 5.3.1.Final tag, I'm getting test failures when in the IDE project. Now, I' am admittedly building with Java 1.7.0_02, so that may be the issue. Has anybody else tried building with Java 7? Did you experience success/failure in doing so?
I'm just wondering whether I need to install a version of Java 6 just to get this building or whether the issue is likely to be something else.
Many thanks,
Steve
p.s. Build summary below...

Re: [rules-users] AUTO MIGRATION Error when creating a new rule package
by the_ricker
I am attempting to use an existing Jackrabbit repository. To do so, I have
added a simple repository confuigurator as follows:
public class GuvnorCrxDavConfigurator extends JCRRepositoryConfigurator {
public GuvnorCrxDavConfigurator() {
log.info("Creating CRX configurator.");
defaultJCRImplClass = RepositoryFactoryImpl.class.getName();
}
@Override
public Repository getJCRRepository(Properties properties) throws
RepositoryException {
log.info("Creating CRX client repository.");
try {
String url = null;
if (properties != null) {
url = properties.getProperty(REPOSITORY_URL);
}
if (url == null) {
url = DEFAULT_URL;
}
log.info("Repository URL is " + url);
repository = JcrUtils.getRepository(url);
if (repository != null) {
log.info("Client repository created.");
} else {
log.error("Repository NOT created.");
}
return repository;
} catch (Exception e) {
throw new RepositoryException(e);
}
}
public Session login(String userName) throws RepositoryException {
log.info("Attempted login with username " + userName);
System.out.println("Logging in with username " + userName);
Credentials credentials = new SimpleCredentials(userName,
"password".toCharArray());
return repository.login(credentials);
}
@Override
public Session login(String userName, String password) throws
RepositoryException {
log.info("Attempted login with username " + userName + " and password " +
password);
System.out.println("Logging in with username " + userName + " and password
" + password);
return super.login(userName, password);
}
public void registerNodeTypesFromCndFile(String cndFileName, Session
session, Workspace workspace)
throws RepositoryException {
log.info("Manually load CND files to CRX");
}
/**
* {@inheritDoc}@see
* org.drools.repository.JCRRepositoryConfigurator#shutdown()
*/
public void shutdown() {
if (repository instanceof TransientRepository) {
((TransientRepository) repository).shutdown();
}
}
}
And I have registered the new configurator in
<component name="repositoryConfiguration">
<property name="properties">
<key>org.drools.repository.configurator</key>
<value>com.statestreet.rxp3.pilot.guvnor.GuvnorCrxDavConfigurator</value>
<key>org.apache.jackrabbit.repository.uri</key>
<value>http://localhost:7402/crx/server</value>
<key>org.drools.repository.admin.username</key>
<value>guvnor</value>
<key>org.drools.repository.admin.password</key>
<value>guvnor</value>
</property>
</component>
The root nodes are created in the repository, but then somewhere in the auto
migration process, it barfs.
I guess I am new territory here.

Need help with a simple predicate
by swaroop
Hi,
Iam trying to upgrade to 5.3.1 final from Drools 5.1 during the process came
across an issue where a simple rule detailed below has an issue when
migrating with respect to the "grade contains("A") || grade contains("B") ||
grade contains("C")" part, This was working in Drools 5.1, any inputs as in
how to restructure this will be helpful
rule "Some - Definitions"
when
$comp : Company()
$emp:Employee(grade contains("A") || grade contains("B") || grade
contains("C"))
then
System.out.println("EMployee is an operations executive");
end
Thanks
Swaroop
