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">
jdbc:hsqldb://192.168.0.XX:3306/mydb?useUnicode=true&characterEncoding=UTF-8</property>
<property name="hibernate.connection.username">user</property>
<property name="hibernate.connection.password">password</property>
<property
name="dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="show_sql">true</property>
<property
name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
<property
name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
<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:
