I have a Repositiory query in my SpringBoot/JPA appliction:

@Query("SELECT w.userId, firstname, lastname "+
            " FROM  WorkflowStep w, User  "+
            " WHERE User.userId = WorkflowStep.userId and workflowId = 145 "+
            " GROUP BY  w.userId, firstname, lastname ")

public List<Activity> getRecentActivity(@Param("workflowId") Integer workflowId)

Which throws an Exception:

“java.lang.IllegalArgumentException: org.hibernate.query.SemanticException: Could not interpret path expression ‘User.userId’ntat org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:138)ntat org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:162)ntat org.hibernate.internal.ExceptionConverterImpl

I feel like the issue is in the Join syntax? Or a problem with my Entity classes?
