Error invoking a Web service in bpmn using activiti

Dear Everyone,

Please help me.

I want to invoke web service in bpmn process.
I try with javadelegate, it works. However, using this java delegate, we have to restart the server every time a new business process is implemented.

So, I try with invoking wsdl directly into bpmn process.
I follow the tutorial in activiti book but I get this error:

errors while parsing:[validation set:'activiti-executable-process'|problem:'activiti-servertask-missing-implementation']': one of the attributes 'class', 'delegateExpression','type','operation' or 'expression' is mandatory on service task. [extra info: processDefinitionId=myProcess|processDefinitionName=my process||id=iservicetask1||activitiname=addition service|]

Here my wsdl content:
