the config is
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource"/>
<property name="transactionManager" ref="transactionManager"/>
<property name="jobExecutorActivate" value="false"/>
<property name="asyncExecutorEnabled" value="true"/>
<property name="asyncExecutorActivate" value="true"/>
<property name="deploymentResources" value="pathtoresourses"/>
</bean>
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration"/>
</bean>
…
Maybe someone can help if there is a problem with the setup.
