Quartz and OpenEJB
Hi,
The last days i started with EJB3 and i must say OpenEJB is a great software
for learning the EJB technology, cause no fat application server is needed,
nearly no configuration, i only have to start the server, deploy/undeploy
EJBs and learn, wonderful. Thanks for that.
But now to my questions:
Is it possible to use the quartz scheduler from an EJB?
if yes, is there any howto?
Does it work if OpenEJB runs in standalone mode, or is an application server
needed ?
thx

Looks like the contents of the zip were simply outdated. The thing
that prevented us from adding that example to our list of examples in
svn was the licensing -- we can't use LGLP code. It's unfortunate as
that example shows people how to use Resource Adapters and it shows
how a great way to get Quartz going in an app.
This has bothered me for a while, so I finally bit the bullet and went
ahead and created an ASL licensed Quartz Resource Adapter. It's
currently in the openejb-core jar, but we'll probably move it to a new
section where we can keep all our resource adapters.
I also fixed up that example to use it and added it to our svn:
http://svn.apache.org/repos/asf/openejb/trunk/openejb3/examples/quartz-app/
I published new 3.1.3-SNAPSHOT binaries, so all you should have to do
is check out the above example and run it.
Give this example a try and let us know how it goes!

This sounds great.

i downloaded the quartz-app.zip but can't get it working:
As suggested first i installed the quartz.jar:
mvn install:install-file -DgroupId=org.jboss -DartifactId=quartz-ra
-Dversion=1.0 -Dpackaging=jar -Dfile=quartz-ra.jar
this worked. Then i:

Thanks for that, too! We appreciate the note.

It is possible to use Quartz to fire events to an MDB via a standard
Java EE Connector. That will work in any compliant EJB container.
We don't have a formal tutorial, but the question has come up and this
post gives quite a few details:
http://old.nabble.com/Re%3A-need-help-getting-quartz-ra.rar-file-to-deploy-p18783086.html
For EJB 3.1 there is a new @Schedule annotation which will be really
quite fantastic. Our implementation will use Quartz under the
covers. We have some work on this now, but nothing complete yet. But
a deeper integration is planned.
Hope this helps!
