(Sorry if this double posts, getting System Admin messages, not sure if
its my SMTP server or some loser on the list sending me that crap)
Most likely, your getTables() is returning null. You can check the
source for DefineTag if you like. I just finished an exhaustive test
suite for that tag, so I know it works 100%.
I would add some debug in your action to verify that its not null.
That's probably your quickest move to finding the culprit.

mfform.setEnd_date(admin.getEndDate());
mfform.setProduct_desc(admin.getProdctDescription());
mfform.setTableNames(admin.getTableNames());
if (mfform.getTables() == null){
LamLog.log(this, LamLog.FATAL,
"Problem getting TableNames from ejb " + e.getMessage());
}
}
catch (Exception e)
{
...
...
Hope that helps.
