Have a way to "bootsrap" the seam engine for batch processes ------------------------------------------------------------ Key: JBSEAM-1680 URL: http://jira.jboss.com/jira/browse/JBSEAM-1680 Project: JBoss Seam Issue Type: Feature Request Components: Core Affects Versions: 1.2.1.GA, 2.0.0.BETA1 Reporter: Denis Forveille It should be possible to write a "pure" batch processes that uses seam components. Seam should provide a way to "bootstrap" the "seam engine" outside any web/jee container to allow programmers to reuse seam components outside a war, typically from a standard "main" method, run with a standard j2se class. Typical scenario/usage for this: - an online application build around seam, POJOs and hibernate. - the business seam components ("managers" + "model" classes) are isolated into a separate jar file (common.jar) - the "view controllers", which are seam components (aka "backing beans") are directly held into the war module - the war module uses the business components held into the common.jar module. - a batch process, which is standard j2se class with a main method, performs some business process by calling the "business" seam components defined in the common.jar file. The high-level algorithm of this "batch" process is the following - bootstrap the seam engine - for each business item to process (maybe tens of thousand or more...): - begin transaction - do some business stuff by calling the seam components in common.jar that read/update the database - commit - shutdown the seam engine For this, we need a class or harness to "boostrap" the seam engine. This harness should not depends on any of the services provided by a typical web/ jee container, this includes: - naming/jndi - security - jsf/jsp/facelets - ...etc The harness should be able to manage injection/bijection of user defined components and also to provide the injection of some non-web dependent object like the hibernate session and the logger. Of course none of the "web" functions are required (Conversation managment, @DataModel etc...) At a minimun, this harness should be able to handle the @Name, @In, @Out, @Create, @Destroy, @Factory, @Transactional, @Logger annotations Big Thanks...
