Subject Re: using torque standalone with struts- NullPointerException on save() method
Date Mon, 15 Dec 2003 08:07:05 GMT
Hi
As i can see this in your log...

[WARN] IDBroker - -IDBroker is being used with db 'torque', which does not
support transactions......bla bla bla

i think that you have configured your torque-generator with a database named
'torque'
i mean in the torque-gen/build.properties file ...and afterwards you are
triyng to
launch torque (Torque.init(...)) using another database..
as i know ..(i am a newbie too) ..these both database must be equal ..
i am not sure whether there is a way to accomplish generation/usage process
with these both properties different

is that of any help ?

with best regards,
bogdan
