- We have two applications running on EAP. Both applications are packaged as EARs. We are getting this exception:
Caused by: java.lang.ClassCastException: com.jboss.examples.jpa.ExampleEntity cannot be cast to com.jboss.examples.jpa.ExampleEntity
We think this is a Class Loader isolation problem. The class com.jboss.examples.jpa.ExampleEntity is contained in a common JAR along with a persistence.xml that is packaged in both EARs. We have isolation enable on both EARs. The common JAR has a persistence.xml which is specifying the JNDI name for the EntityManagerFactory as such:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"> <persistence-unit name="example-jpa.jar" transaction-type="RESOURCE_LOCAL"> ... <properties> ... <property name="jboss.entity.manager.factory.jndi.name" value="java:/ExampleEntityManagerFactory"/> </properties> </persistence-unit> </persistence>
