Hi @fatma_wings,
it seems that your BPMN process is not valid. Please have a look at the reference guide how to use service tasks and exclusive gateways.
Does this help you?

Hi @fatma_wings,
this error says that you must configure the service tasks and choose one option how the Java code should be called. For example:
<serviceTask id="javaService"
name="My Java Service Task"
camunda:class="org.camunda.bpm.MyJavaDelegate" />
Please have a look at the BPMN Get Stared.
Best regards,
Philipp
