Is possible create a library that contains business logic for use in a web project and a desktop project?

I'm working on two java projects that use the same database and the same business logic.
A project is a Web application and the other a desktop application.
I built a project called model containing hibernate libraries for persistence of data and contains dao classes and services for managing business logic.
This project generates a jar that I use in the two applications.
I wonder if this strategy is good or bad?
Not sure if it will bring inconvenience with concurrency.
I welcome any comments.

PS: Sorry for my English level.

This is not really a Hibernate question, but rather a general Java question.

I see no serious problem with a jar shared across two apps. Whether this will create concurrency issues depends mainly on your use of static members, and the classloading policy in use. Are the two apps in the same EAR?

Keep in mind that business logic doesn't *have* to be written in code -- you can use rules engines, things like Automated Business Logic, etc...

Thanks for your Reply!

You're right! Is not really a hibernate question.
The two Applications are in differents Ear.

I use the same jar in both projects, but had to put the credentials directly in the hibernate.cfg.xml

Now, I tried to use a jndi datasource on the web and desktop application.

I created a data pool connection and jndi name for the web app, but i don´t know if its possible use the same jndi in the desktop app.

I'm using glassfish app server.

Thanks!
