The JSR94 standard process was very long (more than 2 years) and very
complicated, with a lot of politics, and a lot of arguing. For me, the
most useful product was the understanding that rule engines are still
a growing, changing field that currently resists meaningful
standardization. 

I don't believe it would be prudent for me to discuss the details of
how the final private decisions about the shape of the package were
made. But the facts are that

1) the final package explicitly does *not* explicitly address the J2EE
environment, and therefore omits those features that are specifically J2EE
oriented. This means that not only the RI excludes J2EE features; it
means that the javax.rules API acknowledges that it's not designed
specifically for J2EE use; and

2) comparatively little of Jess's functionality is conveniently
available through the API defined by JSR94, and so using Jess through
javax.rules makes sense only if you definitely intend to switch rule
engines, and don't mind writing to the lowest commono denominator.
