- Batch process with seam: what is the best approach? 2007-07-16 - By titou09
Back
We have an online application build around seam, POJOs and hibernate.
Our business seam components ("managers" + "model" classes) are isolated into a
separate jar file (common.jar), the "view controler" seam components (aka
"backing beans") are directly held into the war module, the war module calling
the classes into the common.jar module.
We have the need for batch processes, ie processesthat will run outside any web
/jee container, with a standard j2se jdk, from a plain java class, possibly
running for hours. Those processes will use the seam common components from the
common.jar file.
The high level algorithm is :
| - bootstrap the seam engine
| - for each business item to process (maybe tens of thousand or more...):
| - begin transaction
| - do some business stuff that update the database
| - commit
| - shutdown the seam engine
|
What is the best way to do that with seam? Is it possible to do this without
instanciating or faking a web container?, ie without having in the batch
classpath, jars like "servlet.jar" eand "j2ee.jar"? or something like the jboss
embedded container?
We looked at the SeamTest class as the "bootstrap" class, but SeamTest depends
on javax.faces.*, javax.servlet.* and org.testng.* classes and is fully
designed to test online components...
Or maybe the jboss embedded container is the way to go?
Thx for your guidance here.
