JBoss 4.0.2 wiyth Hibernate3 exception org.hibernate.Mapping

[artemis]

Build .har, and deployed.
This is my hbm.xml file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "=//Hinernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.ssi.listener.bean">







</hibernate-mapping>

Built a .war and in a sevlet, had following code:


InitialContext ctx = new InitialContext();
SessionFactory factory = (SessionFactory)
ctx.lookup("java:/org/hibernate/SessionFactory");
Session hsession = factory.openSession();
CWsmType wsmtype = new CWsmType();
wsmtype.setTypeId("123");
wsmtype.setWsmDefaultName("myType"); try {
Transaction transaction=hsession.beginTransaction();
hsession.save(wsmtype);
transaction.commit();
} finally {
hsession.close();
}
Deployed the .war.

At runtime, that is what I see.


14:53:56,312 INFO [STDOUT] org.hibernate.MappingException: Unknown entity: com.ssi.listener.bean.CWsmType
at org.hibernate.impl.SessionFactoryImpl.getEntityPersister(SessionFactoryImpl.java:555)
at org.hibernate.impl.SessionImpl.getEntityPersister(SessionImpl.java:1070)
Why doesnt the session see the persistece object?

Any ideas, inputs? Thanks.

Can you post your deployment descriptors wrapped with [ code ][ / code ] tags without the spaces and use the preview button.

Can you also execute the command 'jar -tf harname.har' and post the output here.

What messages are displayed when you deploy the har?

[artemis]

Here is what I see when I deploy the .har file:

The .har deployment finally succeeded when I switched to Hibernate2. (A table was created in the db). But earlier exception occurs when the servlet in the .war tries to persist the one and only object:

22:56:00,031 INFO [STDOUT] net.sf.hibernate.MappingException: No persister for: com.ssi.listener.bean.CWsmType

Hi,

How did you solve the problem ?

[tyrone.yimin]

I have the same problem.
I Use JBoss AS 4.0.3 SP1 + JBossHibernate2.

[tyrone.yimin]

The *.har be deployed ok.
use a test.jsp such as:

<%@ page import="javax.naming.*" %>
<%@ page import="net.sf.hibernate.*" %>

<%
 InitialContext ctx = new InitialContext();
 SessionFactory factory = (SessionFactory)
 ctx.lookup("java:/hibernate/CmmsSF");
 Session hsession = factory.openSession();
 try {
 Query query = hsession.createQuery("from com.ymsun.entapps.cmms.model.User");
 System.out.println(query.list().get(0));

 } finally {
 hsession.close();
 }
%>

it's ok.
But when i use the spring in my web application such as:

<!-- Hibernate SessionFactory -->
 <bean id="sessionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
 <property name="jndiName"><value>java:/hibernate/CmmsSF</value></property>
 </bean>

 <!-- Transaction manager for a single Hibernate SessionFactory (alternative to JTA) -->
 <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
 </bean>
 ......

then report:

org.springframework.orm.hibernate.HibernateSystemException: Unknown entity class
: com.ymsun.entapps.cmms.model.User; nested exception is net.sf.hibernate.Mappin
gException: Unknown entity class: com.ymsun.entapps.cmms.model.User

i solved the problem, it's seemed that domain classes deployed to *.har can not be deployed to the war again. classloader issue.
