Hi,

You can use the async="true" attribute to let the engine process request asynchronously.

Best regards,

Hi trademak,
Thanks for the reply.
I am using "SpringProcessEngineConfiguration" to initialize/start the Activiti engine.

This is what I have in my spring based config -
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
    <property name="dataSource" ref="dataSource" />
    <property name="transactionManager" ref="transactionManager" />
    <property name="jobExecutorActivate" value="true" />
</bean>

Where do I need to mention "async="true" to start the processing in parallel.

Hi,

If you use Activiti Designer, you can specify that in the properties view of each service task.

Otherwise configure it directly in the xml as described here http://www.activiti.org/userguide/index.html#asyncContinuations in the userguide.
