Hi,
see:
<code>
ServiceTaskValidator.java
protected void verifyType(Process process, ServiceTask serviceTask, List<ValidationError> errors)
…

</code>

if you provide a type for your service task it should be one of the following:
mail, mule ,camel, shell

Understood the error.

But then, how do I specify the implementing class of the serviceTask ?

In XML it is seen as :
<code>
<serviceTask id="someRandomTask" name="Awesome Service Task" activiti:class="ServiceTaskSample"></serviceTask>
</code>

Here we could specify the implementing class as "activiti:class".

But, I couldn't find any method in ServiceTask class, that lets me set this value in code.

Any pointers?

Hi,
this should be enough:
<code>
serviceTask.setImplementationType("class");
serviceTask.setImplementation("be.stacktrace.activiti.dynamicprocess.DynamicActivitiProcessTest.ServiceTaskSample");
</code>

Thanks.

This worked. I didn't find any example/documentation in the official docs about this though.

No, because this is not 'public api'. Most people will not create a process programmatically.
