I think that your problem is that you call FeatureCollection::addFeatures
before setting the transaction - I guess that this means your features are
being added in a different transaction than the one you have a handle to,
so when you commit there are no pending changes. If you reverse the order
of those operations, does it work better? It's also important to ensure
you close the transaction (just declare it outside of your try block and
close it in a finally block.)
BTW, this question would be better suited for the GeoTools users list - if
the above suggestions don't help you'll probably get better help there.
