No JQPL entity name - database table name mismatch, but it also says The abstract schema type 'Movie' is unknown - spring

Question

I want to build a simple web application using Spring, Eclipselink and MySQL, running on Wildfly 8.2. I want to run a simple query, but I'm keep getting this error:
13:47:37,144 ERROR [io.undertow.request] (default task-9) UT005023: Exception handling request to /MovieTimeProject/hello: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager:
Exception Description: Problem compiling [SELECT m FROM Movie m WHERE m.title LIKE 'Eternal sunshine of%'].
[14, 19] The abstract schema type 'Movie' is unknown.
[28, 35] The state field path 'm.title' cannot be resolved to a valid type.

Answer 1

You have not specified the name of the persistence unit to use within your annotation, which should then use a "default" persistence unit. Try specifying your "MovieTime" persistence unit instead:
#PersistenceContext(unitName="MovieTime")
private EntityManager em;
