I am new to calling Rest services and using drools-server. I configured the camel-server.xml and knowledge-services.xml rest service to use xstream marshalling, added my rules and pojo model to the war, and deployed it on tomcat. I wrote a java http client to run the rest service. This is the batch command that I'm sending: <set-global identifier="logger"> <org.apache.commons.logging.impl.Log4JLogger> <name>com.abclegal.rules.integration.StatusChangeTestIntegration</name> </org.apache.commons.logging.impl.Log4JLogger> </set-global> <insert> <com.abclegal.domain.step.VenueValidationStep> <id>0</id> <parentTaskId>0</parentTaskId> <status>PENDING</status> <activatable>false</activatable> <abortable>false</abortable> <completable>false</completable> </com.abclegal.domain.step.VenueValidationStep> </insert> <fire-all-rules/> </batch-execution> this is the rule: rule "Activate VenueValidationStep" dialect "mvel" when $step : VenueValidationStep(activatable == false, status == Status.PENDING) then logger.debug("activating VenueValidationStep"); modify($step) { setActivatable(true), setStatus(Status.ACTIVE); }; return($step); end when I run the client, I can see on the server log that the global was set and the correct rule is running (it writes to the log using the global logger), and i get a 200 response on the http post. However, the response body is empty except for the enclosing xml tags. it contains only: <?xml version='1.0' encoding='UTF-8'?><execution-results/> The behaviour I would like to happen is that the modified $step would be returned from the http post. Apologies if this is another dumb noob question - I hope it's just something simple I've missed. thanks for the help. -- View this message in context: http://drools.46999.n3.nabble.com/drools-server-empty-response-body-tp319...
