I am developing a project in jsf and JPA

I have one table called employees with column
Name,Job_code,Dept_code
For employee table I have a entity

I have another table called ListOfValues with column
Prefix,Lov_code and Lov_desc
Prefix can be JOB(for job) and DEP(for department)

I want to display these columns
Name
Job desc(=lov_desc, comes from ListOfValues for prefix-JOB and lov_code=job_code)
dept_desc(=lov_desc, comes from ListOfValues for prefix-DEPand lov_code=dept_code)

I have got a session bean which does query(em.createquery(....)) and shows data using jsf datatable. It shows Name,Job_code,Dept_code fine. now I want to get job_desc and dept_desc in same table

Can anyone please tell me how to do it. Any help will be highly appreciated.Thanks...
