To build:
    Even if you are not using an entity manager, building this requires a
    JPA implementation (since the mock entity manager still uses JPA
    interfaces). Download an implementation (e.g., the reference implementation
    from GlassFish) and in your environment set

    JAVAX_PERSISTENCE=path_to/javax.persistence.jar

    Then run
    ant

To run:
    In general, to use a MockEntityManager, run

    java <jvmargs> -DMockEntityManager=MockEntityManager \
        -jar jars/StockBatchingPool.jar \
	[core size] [max size] [0|1|2]

    where 
    core size -- optional, default 1, core size of ThreadPoolExecutor
    max size -- optional, default # of CPUs on machine, max size of TPE
    0|1|2 -- optional, default 0
        0: Use a LinkedBlockingQueue
	1: Use a SynchronousQueue
	2: Use an ArrayBlockingQueue of 10,000 elements

Notes on Examples:

Example 9-1:
    java <jvmargs> -jar jars/StockBatchingPool.jar N N
    where N is the number of threads desired in the pool
