hi craig,
is that something i can do at runtime? i don't want to sound unappreciative of the idea, but bundling the same class files into multiple JAR files probably isn't something i could get away with.
regardless, the idea of having persistence.xml embedded in a JAR file is not realistic for standalone use. the consumer of the persistence unit will need to customize persistence.xml to point to the database server they are interested in. unjarring, rejarring isn't practical.
thanks.

if i am using java persistence stand alone, am i able to choose the persistence unit at runtime?
i can't see how to do this, because it appears that the persistence.xml file is read from the classpath.
any ideas?
thanks.
