Proxied Drools

[jpuro <jp...@sterlingtesting.com>]

I would like to use the jsr181:proxy configuration to proxy a call to a
lightweight drools component that I have configured, but I'm not sure I
understand how to do this.  The purpose of doing this is that I would like a
particular web service that I am exposing in ServiceMix to be able to call
an interface's method which when called calls into the ESB and then invokes
a drools component and returns a result from it.  Let's say I have the
following annotated web service.  I do not want the web service to know that
it is calling into ServiceMix to invoke the drools component.

@WebService
public class OrderService {

    private RuleService ruleService;

    @WebMethod
    public void submitOrder(Order order) {
        
        if ( ruleService.isValidOrder(order) ) {
                // Let's save the order now
                ...
        }

    }
}

Here's the interface for the RuleService:

public interface RuleService {
    
    public boolean isValidOrder(Order order);

}

Here is what I'm guessing the configuration may look like:

<sm:activationSpec>
	<sm:activationSpec componentName="droolsComponent"
service="test:droolsService">
		<sm:component>
			<bean class="org.apache.servicemix.components.drools.DroolsComponent">
				<property name="ruleBaseResource">
					<value>classpath:META-INF/rules/rulebase.xml</value>
				</property>
			</bean>
		</sm:component>
	</sm:activationSpec>
</sm:activationSpec>

<jsr181:proxy id="ruleServiceProxy"
  container="#jbi"
  service="test:droolsService"
  type="com.sterling.test.RuleService"/>

Any help would be appreciated.

Thanks,

Jeff

Currently, the jsr181 proxy only supports JBI endpoints that
expose a WSDL.  This should be easy to fix, please raise a
JIRA for that.

As a workaround, you may want to write a simple WSDL
according to your java interface and override the
DroolsComponent to return this wsdl to the JBI container by
overriding:
    public Document getServiceDescription(ServiceEndpoint endpoint) {
        return null;
    }
