Hi,

I am new to camunda BPM, I have downloaded wildfly 10 full distribution and tried to deploy the below camunda-spring shared process engine application.But i was not able to deploy it.
https://github.com/camunda/camunda-get-started-spring/archive/Bonus.zip

It throws the following error.

ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool – 94) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host."/loanapproval-spring-0.1.0-SNAPSHOT": org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host."/loanapproval-spring-0.1.0-SNAPSHOT": java.lang.RuntimeException: org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.camunda.bpm.BpmPlatform] for bean with name ‘processEngineService’ defined in ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: org.camunda.bpm.BpmPlatform from [Module “deployment.loanapproval-spring-0.1.0-SNAPSHOT.war:main” from Service Module Loader]

Appreciate the response.

Hi @mallagam,

SpringServletProcessApplication does not work on JBoss/Wildfly as stated here. Instead, create a custom subclass of ServletProcessApplication similar to

github.com

camunda/camunda-bpm-examples/blob/master/deployment/spring-servlet-pa-jboss/src/main/java/org/camunda/bpm/example/spring/servlet/pa/SpringServletProcessApplication.java#L24-L40


@ProcessApplication
public class SpringServletProcessApplication extends ServletProcessApplication {


@PostDeploy
public void startProcess(ProcessEngine processEngine) {
  System.out.println("Invoking @PostDeploy annotation in " + getClass().getName());
  System.out.println("Starting testResolveBean processdefinition");
  processEngine.getRuntimeService().startProcessInstanceByKey("testResolveBean");
  System.out.println("Starting testResolveBeanFromJobExecutor processdefinition");
  processEngine.getRuntimeService().startProcessInstanceByKey("testResolveBeanFromJobExecutor");
}


@PreUndeploy
public void remove() {
  System.out.println("Invoking @PreUndeploy annotation in " + getClass().getName());
  System.out.println("Undeploying SpringServletProcessApplication-Example");
}

See the entire example for clarification.

Cheers,
Thorben
