I have a hibernate application. All entity classes plugged in in a separate jar file. The config is the following:
<bean id="myEntityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath:/META-INF/persistence.xml" />
<property name="persistenceUnitName" value="MyPersistenceUnit" />
<property name="dataSource" ref="myDataSource" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<property name="jpaDialect" ref="jpaDialect" />
<property name="packagesToScan" value="mypackage" />
</bean>
And persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0" >
<persistence-unit name="MyPersistenceUnit">
<properties>
<property name="hibernate.dialect" value="mypackage.domain.MyInformixDialect"/>
<property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
<property name="hibernate.show.sql" value="false"/>
<property name="hibernate.current_session_context_class" value="thread"/>
<property name="hibernate.archive.autodetection" value="class"/>
</properties>
</persistence-unit>
</persistence>
When I run my application,I get
java.lang.ArrayIndexOutOfBoundsException: 0
When I tried to debug, I found a section:
file: package org.hibernate.hql.internal.QuerySplitter
if ( results.length == 0 ) {
LOG.noPersistentClassesFound( query );
}
Line 130, hibernate version is 4.3.8.Final
So, my entities seems has not been loaded. Why? Why can't it scan them from a jar file? I checked package names, persistence.xml is in META-INF folder, etc. What's wrong?
UPDATE
The stacktrace is below:
