Axis2 And Hibernate
Hello,
I have a problem with Axis2 and hibernate. I have a web application project
that access to a MySQL database with hibernate. This project works fine.
Now I want to create a web service interface using the methods that access
to the database. So I invoke this classes from my web service project. The
problem is that I receive an exception like that:
RPCMessageReceiver.invokeBusinessLogic - Resource:src/com/model/Poi.hbm.xml

Re: Axis2 And Hibernate
Posted by dpeinador <da...@yahoo.es>.
Hello,
I have just solved it. I have included the *.hbm.xml files in the
.\WEB-INF\classes directory of Axis2.
Thank you

Re: Axis2 And Hibernate
Posted by Eric Isley <er...@gmail.com>.
Hi,
I had a similar issue recently while trying to configure and use
iBatis with an Axis2 web service. I posted a similar thread but never
got any responses. From what I understand it's not finding your
hibernate configuration because of the way the classloading is
happening inside the web service. If you add the following line to
your services.xml file under the <service> node it should work:
<parameter name="ServiceTCCL">composite</parameter>
You can read about this at: http://wso2.org/blog/dims/1131
Once I did that my iBatis config files could be loaded but then I lost
the JNDI datasource that I had set up and I decided that I would
rather have connection pooling from the Tomcat server than use iBatis.
I wish there was a way to easily include .properties files and .xml
files onto the classpath from inside the .aar automatically so it
didn't just ignore them. Once you set that parameter see if you can
use a datasource lookup.
Good luck!

Re: Axis2 And Hibernate
Posted by dpeinador <da...@yahoo.es>.
Hello all,
I continue trying to fix the mis configuration. I have isolated the Web
service, First I have create a dummy Echo Web service, and when this Web
service has been working. I hav added the hibernate classes.
This is the Echo Class (Echo,java):
package com.autentia.ws.servidor;
import com.db.PoiManager;
import java.util.List;
public class Echo {
public String hello(String nombre) {
PoiManager pm = new PoiManager();
List l = pm.listPois();
return "Hola " + nombre + ". Numero de POIs: " + l.size();
}
}
And the Poi classes:
PoiManager.java:
package com.db;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.classic.Session;
public class PoiManager {
private SessionFactory sessionFactory;
public PoiManager() {
try {
System.out.println("Inicalizando Hibernate");
sessionFactory = new Configuration().configure().buildSessionFactory();
System.out.println("terminado la inicializacion de Hibernate");
} catch (HibernateException e) {
e.printStackTrace();
}
}
public List listPois() {
try {
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
List result = session.find("from poi");
tx.commit();
session.close();
return result;
} catch (HibernateException e) {
throw new RuntimeException(e.getMessage());
}
}
}
Poi.java:
public class Poi {
private Long idItem;
private String descripcion;
public Long getIdItem() {
return idItem;
}
public void setIdItem(Long idItem) {
this.idItem = idItem;
}
public String getDescripcion() {
return descripcion;
}
public void setDescripcion(String descripcion) {
this.descripcion = descripcion;
}
}
This is my Poi.hbm.xml file:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//hibernate/hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="com.cb.Poi" table="poi">
<id name="id" column="IDITEM" type="long">
<generator class="identity"/>
</id>
<property name="descripcion" column="DESCRIPCION" type="string"/>
</class>
</hibernate-mapping>
I have created also the hibernate.cfg.xml file and I have put it in the
WEB_INF/classes Axis directory:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property
name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="hibernate.connection.url">

<property name="hibernate.hbm2ddl.auto">update</property>
<mapping resource="com/db/data/Poi.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Whit this classes I build the .aar file, I upload it and create the client
from the wsdl file. When I execute the client I receive this log:
