You might want to look at Spring Batch at
http://static.springsource.org/spring-batch/
Spring Batch can share your Spring Framework POJOs of your web
application but it really makes sense for these to be stand alone
processes as there is no user interaction.

Hi,
I need to execute some time intensive batch jobs in my application,
such as periodically loading data from a file into a database,
happening at regular intervals and taking maybe 10-20 minutes. I am
thinking about where I should put the logic, inside a Spring Manager
bean that I access with a web service, or if I should just write a
simple command line program to do this.
I of course would prefer to have it within my appfuse project since
then I can use my existing model/dao classes and have all my code base
in one place. But I am a little afraid that there might be some
pitfalls in running such a heavy batch job within the web container
and accessed through a web service, for example timeout and
performance problems. I would love to get some feedback on that. Also
am I maybe missing a better way, is there for instance some way of
calling a method of a Spring Manager bean in appfuse directly from the
command line? It would of course need to be setup in the same way (all
decencies injected).
best regards,
Magnus
