Mike,
In the past I saw a few open source frameworks for standalone
embeddable JNDI object bindings. Don't remember the project name
though. Try googling it, you may find more than one such framework out
there.
Still none of them are likely to help you with reusing existing OAS
JNDI configuration. I would imagine every such framework will have its
own configuration requirements. So using "cdeploy" doesn't sound more
complex than any such embedded JNDI framework.
