Hi,

I'm developing a web application which has a module to dynamically create mapping hbm.xml files and save into class path.

Every time I create a hbm.xml mapping file I have to load that to sessionFactory. This will results reinitialization of connection pooler hence reduce the speed of the application.

Is there any way to auto ditect the dynamically created hbm.xml mapping files without explicitly loading to sessionFactory?

Really appreciate any help.
Thank you.

I don't think so.
How else would you be able to get all those associations working correctly?
You need to build new session factory.

Yes, I also realise that it will be a impossible task.

But....

According to following links, it seems (But havent tried) that Jboss+Hibernate will support hot deployement of hbm.xml mapping files.

But my web application is running on Tomcat. Is there any way to achive this?

Thank you.

I think this hot deployment is used structly in JBoss, using their deployer architecture. But is is meant to deploy the whole persistence unit - a closed archive of entities (not being associated outside this archive).
So if your newly created entities are only dependant on them self, use JBoss and this new persistence-unit feature.

Hi,
If I dynamically create hbm.xml files and put a new entry in hibernate.cfg.xml (as <mapping resource="beyondm/hibernate/main/XXX_SyatemUser.hbm.xml"/>) dyanmically at run time, then am I need to create a sessionFactory again?

I have no such experience, but I think so.
