This quick fix for next error markers:
1. Non-static method <method>() of a session bean class <class> has a parameter annotated @Disposes, and the method is not a business method of the session bean [JSR-299 §3.3.6]
2. Non-static method <method>() of a session bean class <class> has a parameter annotated @Observes, and the method is not a business method of the EJB [JSR-299 §10.4.2]

Quick fix should make the method a business method of the EJB
