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
