Issue with with spring frame work Integration with Camunda BPM

[suresh.t...@gmail.com]

Hi,
I deployed spring framework integration tutotrial to the tomcat server and BP Engine pointing to H2 database. i could not see any process defintions in cockpit or tasklist that are provided in spring framework integration Application. I provided database infomation in application-context.xml and process definitions mentioned processes.xml. even i tried with Auto-deployment also.
Please provide me is it possible see spring framework application process definitions in cockpit or tasklist or do i need to do any thingfor displaying process defintions in cockpit or tasklist.

regards,
suresh

Hi Suresh,

have you got a message at the console that your processes have been deployed successfully? Do you use an embedded or a shared process engine?

Cheers,

Roman

Hi,
Yes, I got message that process deployed successfuly but i could not see that that process from cockpit or tasklist. Please give details of how we can configure embedd. or shared process Engine.

Hi Suresh,

you are using an embedded process engine, so that in that case this engine will not be registered with the BpmPlatform and cockpit has no access to this process engine and will not show the your deployed processes. Use therefore instead of an embedded process engine a shared process engine, see here how to configure a shared process engine in context of spring:

http://docs.camunda.org/latest/guides/user-guide/#spring-framework-integration-process-engine-configuration

Furthermore, see here how to configure a spring process application:

http://docs.camunda.org/latest/guides/user-guide/#process-applications-the-process-application-class-the-springprocessapplication

Does it help you?

Cheers,

Roman

Hi,
Thank you for providing Information and i tried with configuring org.camunda.bpm.engine.spring.container.ManagedProcessEngineFactoryBean in application-context.xml but process definitions are not reflecting cockpit or tasklist.

regards,
suresh

Hi Suresh,

try the following configuration (I assume that you want to definie and use a shared engine):

META-INF/processes.xml

<?xml version="1.0" encoding="UTF-8" ?> 

<process-application 

     xmlns="http://www.camunda.org/schema/1.0/ProcessApplication" 

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 

  <process-archive name="loanspringtest">

    <properties> 

      <property name="isDeleteUponUndeploy">false</property> 

      <property name="isScanForProcessDefinitions">true</property> 

    </properties> 

  </process-archive> 

   

</process-application>

(1): The process archive loanspringtest will be deployed to the process engine with the name engine. (see http://docs.camunda.org/latest/guides/user-guide/#process-applications-the-processesxml-deployment-descriptor)

(2): Configure a process engine and set the name of the process engine to engine.

(3): Configure a shared (container-managed) process engine using the class ManagedProcessEngineFactoryBean (see http://docs.camunda.org/latest/guides/user-guide/#spring-framework-integration-process-engine-configuration-configuring-a-container-managed-process-engine-as-a-spring-bean)

(4): Configure a SpringServletProcessApplication to bootstrap the SpringProcessApplication (see http://docs.camunda.org/latest/guides/user-guide/#process-applications-the-process-application-class-configuring-a-spring-process-application).

Furthermore, you have to set the scope of the Maven dependency of the camunda-engine dependency to provided inside your pom.xml (see http://camunda.org/get-started/spring-framework.html#bonus-chapters-use-shared-process-engine-on-apache-tomcat).

Then build your process application and deploy it to your tomcat distribution, open cockpit and change the process engine from default to engine (that is the process engine you defined inside the applicationContext.xml), see http://docs.camunda.org/latest/guides/user-guide/#cockpit-start-page-view-multi-tenancy. There you have to create an initial admin user, login with this new user to the process engine engine and switch back to cockpit. There your deployed process definitions should be visible.

Hi,
I followed below steps still i could not see deployed process definition on cockpit. Do i need change any thing in bpm-platform.xml.

Hi Romon,
Now i am able to see deployed process definitions in cockpit with below steps.
Earlier i missed camunda-spring jar file in pom.xml. Thank you for your help.
