Hi all.
I have a problem.
I use:
Hibernate 3.2.2Beta1
Eclipse SDK 3.3.2
Java jre1.6.0_04
Mysql 5
Tomcat 5.5
I have created a dynamic web application with Eclipse.
I have followed the instructions of the guide
http://docs.jboss.org/tools/2.1.0.Beta1 ... index.html # plugins.
I have created the file:
- Hibernate.cfg.xml,
Code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

if I use HQL Editor and run the query:
Code:
form HsHrEmployee
the query is successful.
If I use the following code:
Code:
HsHrEmployee employe = new HsHrEmployee();
HsHrEmployeeHome home = new HsHrEmployeeHome();
employe.setEmpNumber(2);
employe.setEmpFirstname("JavaCognome");
employe.setEmpLastname("JavaNome");
home.persist(employe);
the system generates the following error:

I have configured JNDI as follows
I have included in the file web.xml the following code:
Code:
<resource-env-ref>
<description>Sample Hibernate SessionFactory</description>
<resource-env-ref-name>hibernate/SampleSessionFactory</resource-env-ref-name>
<resource-env-ref-type>org.hibernate.SessionFactory</resource-env-ref-type>
</resource-env-ref>
I have included in the file server.xml the following code:
Code:
<Context >
<Resource name="hibernate/SampleSessionFactory"
auth="Container"
type="org.hibernate.SessionFactory"
factory="data.HibernateSessionFactoryTomcatFactory"
configuration="hibernate.cfg.xml"/>
</Context>
I have created the class for the factory
Code:
public class HibernateSessionFactoryTomcatFactory implements ObjectFactory{
public Object getObjectInstance(Object obj, Name name, Context cntx, Hashtable env)
throws NamingException{
SessionFactory sessionFactory = null;
RefAddr addr = null;
try{
Enumeration addrs = ((Reference)(obj)).getAll();
while(addrs.hasMoreElements()){
addr = (RefAddr) addrs.nextElement();
if("configuration".equals((String)(addr.getType()))){
sessionFactory = (new Configuration()).configure((String)addr.getContent()).buildSessionFactory();
}
}
}catch(Exception ex){
throw new javax.naming.NamingException(ex.getMessage());
}
return sessionFactory;
}
}
I have changed the look up in the HsHrEmployeeHome
Code:
protected SessionFactory getSessionFactory() {
try {
return (SessionFactory) new InitialContext().lookup("java:comp/env/hibernate/SampleSessionFactory");
} catch (Exception e) {
log.error("Could not locate SessionFactory in JNDI", e);
throw new IllegalStateException(
"Could not locate SessionFactory in JNDI");
}
}
But the system generates the following problem
Code:
