Jbpm 6.3.0 as a module in Jboss 6.3 EAP

nareshiytha Dec 14, 2015 8:23 PM

Hi,

I am trying to use JBPM 6.3.0 as a module in JBoss EAP 6.3 and not able to succeed since I get ClassNotFoundException during deployment.

(I have developed a restful service using JAX-RS api which exposes process/task operations as services for external entities to consume.)

Below is the stack trace

Below steps have been done so far

[1] Configured MySQL in JBoss

[2] I was able to get the 6.3 modules from http://repository.jboss.org/nexus/content/groups/public/org/kie/kie-eap-distributions-bpms-layer/

[3] Defined the global-modules in standalone.xml

[4] Loading the persistence.xml from the WEB-INF/classes/META-INF of the war

[5] Included the jbpm module in jboss-deployment-structure.xml@

My module.xml is

<resource-root path="jbpm-executor-6.3.0.Final.jar"/>

<resource-root path="jbpm-shared-services-6.3.0.Final.jar"/>

<resource-root path="jbpm-audit-6.3.0.Final.jar"/>

<resource-root path="jbpm-human-task-audit-6.3.0.Final.jar"/>

<resource-root path="jbpm-query-jpa-6.3.0.Final.jar"/>

<resource-root path="jbpm-human-task-jpa-6.3.0.Final.jar"/>

<resource-root path="jbpm-workitems-6.3.0.Final.jar"/>

<resource-root path="jbpm-bpmn2-6.3.0.Final.jar"/>

<resource-root path="jbpm-flow-builder-6.3.0.Final.jar"/>

<resource-root path="jbpm-flow-6.3.0.Final.jar"/>

<resource-root path="jbpm-persistence-jpa-6.3.0.Final.jar"/>

<resource-root path="jbpm-runtime-manager-6.3.0.Final.jar"/>

<resource-root path="jbpm-services-api-6.3.0.Final.jar"/>

<resource-root path="jbpm-workitems-6.3.0.Final.jar"/>

<resource-root path="drools-persistence-jpa-6.3.0.Final.jar"/>

</resources>

</dependencies>

</module>

Included the below dependencies in pom.xml

<version>${jbpm.version}</version>

<scope>provided</scope>

<artifactId>kie-internal</artifactId>

</exclusion>

<artifactId>drools-core</artifactId>

<groupId>org.drools</groupId>

</exclusion>

<artifactId>protobuf-java</artifactId>

<groupId>com.google.protobuf</groupId>

</dependency>

<artifactId>hibernate-jpa-2.0-api</artifactId>

<groupId>org.hibernate.javax.persistence</groupId>

<version>1.0.1.Final</version>

<scope>provided</scope>

</dependency>

Below is the code snippet that defines the RuntimeManager

private RuntimeManager getRuntimeManager(List<String> processList) {

EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.domain");

RuntimeEnvironment environment = RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder()

.entityManagerFactory(emf)

.userGroupCallback(new UserGroupCallback() {

public List<String> getGroupsForUser(String userId, List<String> groupIds, List<String> allExistingGroupIds) {

...

}

Can anyone please help me to get this fixed?
