Question

I have many jsf2 web projects that use the same validation constraints.

1. Can I put all these constraints in a shared library?
2. If yes, can I supply traslations for the validation messages?
3. If yes, how can I achieve it in a standard way?
4. Is the following package structure correct?

commons.jar library:

commons.jar
    |
    + library
    |   |
    |   + CustomConstraint1.class
    |   + CustomConstraint2.class
    |
    + ValidationMessages_it.properties
    + ValidationMessages_en.properties
    + ValidationMessages_de.properties

Answer 1

Your bundling is right for a standalone jar. It won’t work if you drop this jar into a ear/war with it’s own constraints and a ValidationMessages.properties in the root of the classpath.
