Can I deploy JPA jars per application ?

[Jose Campana]

Hello there !

Just one quick question so as not to bore you with extensive text.

Can I deploy the JPA jars as part of one enterprise application ?

I need to know if it's possible so that I can avoid creating a shared library inside the container. The JPA implementation I'm using is EclipseLink.

Thanks in advance.

Jose.

I prefer to do it that way.

Imagine you had 10 applications using JPA 1.0, and they all referenced the same set of JARs. Then, imagine you wanted to update one application. If your rule is that all apps point to the same JARs, you'd have to update all 10 apps at the same time. How much sense does that make?

My personal preference of course.

You can, but this can depend on which application server you are using.

Generally a single shared jar is used.
