Thanks, Forrest. I am using the Ration OSGi tool. I somehow forgot to check the box to compile the servlet class into the WEB-INF/classes folder.
Now, I'm trying to figure out how to write to a Postgres db using jdbc. I haven't been able to find any good examples. Can you point me to one or give me some tips on how to go about it? Once again, thanks for the help. michael On Apr 19, 2012, at 9:24 PM, Forrest Xia wrote: > Two points here: > 1.
