no. Restructure that monstrosity first, think about what it is you want, and give a LOT more information.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

I am sorry that you don't understand this code. The entire program works beautiful. I asked a simple question. It's clear you don' know . Thank you anyway.

I don't even bother to read such huge reams of code, especially if it's all in a single class.
It indicates a total lack of interest on your part in not only doing a decent job at your assignment but also in showing what your problem is.

Chapter 9. Queries and EJB QL

Querying is a fundamental feature of all relational databases. It allows you to pull complex reports, calculations, and information about intricately related objects from persistence storage. Queries in Java Persistence are done using both the EJB QL query language and native Structured Query Language (SQL).

EJB QL is a declarative query language similar to the SQL used in relational databases, but it is tailored to work with Java objects rather than a relational schema. To execute queries, you reference the properties and relationships of your entity beans rather than the underlying tables and columns these objects are mapped to. When an EJQ QL query is executed, the entity manager uses the information you provided through the mapping metadata, discussed in the previous two chapters, and automatically translates it to one (or several) native SQL query. This generated native SQL is then executed through a JDBC driver directly on your database. Since EJB QL is a query language that represents Java objects, it is portable across vendor database implementations because the entity manager handles the conversion to raw SQL for you.
9.1. Query API

A query in Java Persistence is a full-blown Java interface that you obtain at runtime from the entity manager:
Code View: Scroll / Show All
Java Syntax (Toggle Plain Text) 
  1. package javax.persistence;
  2.  
  3. public interface Query {
  4.    public List getResultList( );
  5.    public Object getSingleResult( );
  6.    public int executeUpdate( );
  7.    public Query setMaxResults(int maxResult);
  8.    public Query setFirstResult(int startPosition);
  9.    public Query setHint(String hintName, Object value);
  10.    public Query setParameter(String name, Object value);
  11.    public Query setParameter(String name, Date value, TemporalType temporalType);
  12.    public Query setParameter(String name, Calendar value, TemporalType temporalType);
  13.    public Query setParameter(int position, Object value);
  14.    public Query setParameter(int position, Date value, TemporalType temporalType);
  15.    public Query setParameter(int position, Calendar value, TemporalType temporalType);
  16.    public Query setFlushMode(FlushModeType flushMode);
  17. }
In that one class. can someone tell me to where to add a new query?

public interface EntityManager

Interface used to interact with the persistence context.

An EntityManager instance is associated with a persistence context. A persistence context is a set of entity instances in which for any persistent entity identity there is a unique entity instance. Within the persistence context, the entity instances and their lifecycle are managed. This interface defines the methods that are used to interact with the persistence context. The EntityManager API is used to create and remove persistent entity instances, to find entities by their primary key, and to query over entities.

The set of entities that can be managed by a given EntityManager instance is defined by a persistence unit. A persistence unit defines the set of all classes that are related or grouped by the application, and which must be colocated in their mapping to a single database.

hopefully this will explain a little about entity.createQuery();
