Error While Deploying the pizza-order project

Hello All,

I am new to Camunda community and trying to learn the same. While following steps of “EJB Service Task” through “https://docs.camunda.org/get-started/javaee7/service-task/” I am getting the below error while deploying the .war file.
I am using
1)7.9.0 Camunda Wildfly for my practice.
2) Eclipse version - Version: 2020-03 (4.15.0)
