hibernate properties not found

Question

we are integrating the java blazeds hibernate with flex project..First we tested the pure java hibernate in eclipse and it is executing fine. But when we put the same in tomcat for flex integration with blazeds it is showing the following error.this is the only error.

Jan 24, 2013 11:31:31 AM org.hibernate.cfg.Environment <clinit>
INFO: Hibernate 3.2.6
Jan 24, 2013 11:31:31 AM org.hibernate.cfg.Environment <clinit>

Jan 24, 2013 11:31:31 AM org.hibernate.cfg.Configuration getConfigurationInputSt
ream
INFO: Configuration resource: /hibernate.cfg.xml

this is the hibernate.cfg.xml(To identify whether hibernate.cfg.xml is not found and i tested by deleting DOCTYPE of .cfg.xml then tomcat output displayed saying the root element is not found...which means it is able to find the hibernate.cfg.xml( i think)

 <?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">

        <mapping class="com.model.User" />
        <mapping class="com.model.UserDetails" />
        <mapping class="com.model.LoanDetails" />
        <mapping class="com.model.BorrowerDetails" />

    </session-factory>
</hibernate-configuration>

this is hiberutil.java

public class HibernateUtil
{



    private static  SessionFactory sessionFactory=configureSessionFactory();
    private static ServiceRegistry serviceRegistry;


    private static SessionFactory configureSessionFactory() throws HibernateException {
        Configuration configuration = new Configuration();
        configuration.configure();
        serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        return sessionFactory;
    }
    public static SessionFactory getSessionFactory()
    {
        return sessionFactory;
    }
}

why the error is showing? the control is coming from flex side and executing the starting point of the java method...but when it comes to hibernate stuff execution, it is showing this error in tomcat...

But when i execute java+hibernate as a pure java application it is executing fine..

can anybody help me?

Thanks

EDIT 1 After the modification suggested by @Andremoniy and putting the .cfg.xml in src folder and here also in eclipse it is working but not in tomcat with flex

following error comes

Answer 1

It seems to me, that you can solve this problem, by passing hibernate.cfg.xml directly into Configuration.

try (InputStream in = HibernateUtil.class.getResourceAsStream("/hibernate.cfg.xml")) {
     Configuration configuration = new Configuration().addInputStream(in).configure();
...
} ... 

The only thing, you have to properly point the path or class, for getResourceAsStream. Or you may be want to create InputStream using some relative path.

Answer 2

if it is appeared that you use Intellij Idea you need to put hibernate.cfg.xml file into resources folder

and if you will have after next error: org.hibernate.service.jndi.JndiException: Error parsing JNDI name []

delete in hibernate.cfg.xml file name of tag see picture:

Answer 3

I have faced the same problem but I found the solution here..

http://www.mkyong.com/hibernate/hibernate-error-an-annotationconfiguration-instance-is-required-to-use/

ie. Change the line:

new Configuration().configure().buildSessionFactory();

to:

new AnnotationConfiguration().configure().buildSessionFactory();

Answer 4

I guess the problem is with the code for configuration you mentioned for .hbm.xml may not be working in Tomcat.

I think it needs AnnotationConfiguration object. I guess you used this code due to the Annotationconfiguration object creation is not working.

Better create a maven hibernate project with pom and export the war file to Tomcat (with the changes of Annotationconfiguration). Also use log4j jar for showing the details of Tomcat execution with the debug outputs, so that Tomcat output will print all of execution flow.
