<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The exact scope of <tt>ValidatorFactory</tt> in Java EE (with and without CDI) is a bit unclear. Let's try and improve this.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In an ideal world, there should be one <tt>ValidatorFactory</tt> instance per application.<br /> This is what the Bean Validation integration chapter describes. The wording is a bit unclear unfortunately</p>
<blockquote style="margin: 10px 0 0 0; border-left: 1px solid #ccc; color: #707070; margin-left: 19px; padding: 10px 20px">
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">build and bootstrap the ValidatorFactory instance for an application.</p>
</blockquote>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">This is inconsistent with the Java EE umbrella specification which states that:</p>
<ul class="alternate" type="square">
<li>
we have one <tt>ValidatorFactory</tt> per module (WAR, EJB, etc)
</li>
<li>
there is no per-application validation deployment descriptor
</li>
</ul>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The reason the Java EE spec got worded that way to make the rules simple on what <tt>META-INF/validation.xml</tt> file is to be considered. If two different modules have two different <tt>validation.xml</tt> files, things are unpredictable. So we chose to follow the same logic followed by JPA and its <tt>persistence.xml</tt> file. The benefits of that approach is that EJBs written "in isolation" from one another (with different <tt>validation.xml</tt> for example) will work as expected.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0"><a href="https://hibernate.atlassian.net/secure/ViewProfile.jspa?name=mtaube" class="user-hover" rel="mtaube" style="color: #3b73af; text-decoration: none">Mason Taube</a> proposed to introduce an EAR level <tt>META-INF/validation.xml</tt> to define an app level <tt>ValidatorFactory</tt>. I like the idea. We would then have a clear app level factory and we can decide to either:</p>
<ul class="alternate" type="square">
<li>
raise an exception at deployment time if other <tt>validation.xml</tt> are present in modules
</li>
<li>
have a different <tt>ValidatorFactory</tt> instance for modules that override <tt>validation.xml</tt>
</li>
<li>
force the app level <tt>validation.xml</tt> to have precedence
</li>
</ul>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I am not sure if such global / per-module construct exists today in Java EE. We probably should model it similarly.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In CDI, the reference implementation makes <tt>ValidatorFactory</tt> application scoped. This breaks the Java EE spec wording and does not implement the per-module logic. The initial step, I think is to update the Bean Validation specification to clarify that in Java EE, we should follow the per module isolation.</p>
