<div class="jive-rendered-content"><p>Quoting from that blog:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;">&#160;</p><pre class="jive-pre"><code class="jive-code">When using bean validation on JPA entities within an EJB 3 bean you&#160; would actually get an EJBTransactionRolledbackException if there is a&#160; constraint violation.

javax.ejb.EJBTransactionRolledbackException: Invalid object at persist time for groups [javax.validation.groups.Default, ]
Caused by: javax.validation.ConstraintViolationException: Invalid object at persist time for groups [javax.validation.groups.Default, ]



This&#160; is all nicely according to specification, but not really interesting&#160; information. You don't really want to know what happened, you want to&#160; know what went wrong.



So I recommend adding the following to your&#160; ejb-jar.xml:



&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;ejb-jar
&#160;&#160;&#160;&#160;&#160;&#160;&#160; xmlns="http://java.sun.com/xml/ns/javaee"
&#160;&#160;&#160;&#160;&#160;&#160;&#160; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
&#160;&#160;&#160;&#160;&#160;&#160;&#160; xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"
&#160;&#160;&#160;&#160;&#160;&#160;&#160; version="3.0"&gt;
&#160;&#160; &lt;assembly-descriptor&gt;
&#160;&#160;&#160;&#160;&#160; &lt;application-exception&gt;
&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; &lt;exception-class&gt;javax.validation.ConstraintViolationException&lt;/exception-class&gt;
&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; &lt;rollback&gt;true&lt;/rollback&gt;
&#160;&#160;&#160;&#160;&#160; &lt;/application-exception&gt;
&#160;&#160; &lt;/assembly-descriptor&gt;
&lt;/ejb-jar&gt;
