Hi,

It's a bit difficult to say without the Activiti and Camel context XML files.
Can you include them?

Best regards,

Hi,

Thanks for your reply.

Actually I didn't have any separate Activiti and Camel context XML files. Because, I am using the activiti-explorer web application to test the activiti. In that I have configured

applicationContext.xml

like below. After I configured like below I could see the message like Apache Camel 2.10.0 (CamelContext: camelProcess) started in 0.188 seconds

Okay, and did you also include the Camel route classes in the classpath of the Activiti Explorer web application?
With your configuration it scans for routes in this package:

<package>org.activiti.camel.route</package>

Are there routes available in that package?

Best regards,

In the article there's the following line:

" If you want to test a bit with this example yourself you can checkout the activiti-camel module in our Github repository and execute the AsyncProcessTest in that project." Doesn't that work for you?

         I tried the same example but it does not work. My serviceTask has extensionElement of activiti:field. Also before adding camel, I had acitiviti:Class with a deletage class. So I also need my service task to execute some code in the delegate class. Here is an excerpt from my bpmn file
<serviceTask id="comb-rgb" name="combineimages2rgb" activiti:async="true" activiti:exclusive="false" activiti:type="camel">
          <extensionElements>
            <activiti:field name="ipField">
              <activiti:string><![CDATA[-ImageOut,-ImageR,-ImageG,-ImageB]]></activiti:string>
            </activiti:field>
</extensionElements>
        </serviceTask>

My routes code

public class AsyncCamelRoute extends RouteBuilder{
@Override
public void configure() throws Exception {


from("activiti:emetricsAlgParallel:receiveParamFileSubProc?copyVariablesToProperties=true")
     .setHeader("destination", constant("activiti:emetricsAlgParallel:receive1"))
     .to("seda:asyncQueue1");

   from("seda:asyncQueue1")
   .to("bean:sparky?method=execute")
      .to("seda:receiveQueue");

   from("activiti:emetricsAlgParallel:receiveImageFileSubProc?copyVariablesToProperties=true")
     .setHeader("destination", constant("activceimniti:emetricsAlgParallel:receive2"))
     .to("seda:asyncQueue2");

   from("seda:asyncQueue2")
   .to("bean:sparky?method=execute")
     .to("seda:receiveQueue");

Now I get the following error

Field definition uses unexisting field 'ipField' on class org.activiti.camel.impl.CamelBehaviorDefaultImpl
