I am doing a very simple test in hibernate 2.1,

I have a table Test1 (
id NUMBER(19, 0),
name VARCHAR2(255),
primary key(id)

)

my Test1 class:
public class Test1 {
private Long id = null;
private String name = null;

public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}


my mapping file Test1.hbm.xml:

[b]Mapping documents:<?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="Test1" table="TEST1" >
<id name="id" column="ID" type="long" unsaved-value="null">
<generator class="org.jbpm.persistence.hibernate.ConfigurableIdGenerator" />
</id>
<property name="name" column="NAME" type="string" />

</class>
</hibernate-mapping>
[/b]

my calling class:

[b]public void testHibernate(){
try{
Connection conn = null;

conn = DriverManager.getConnection("jdbc:oracle:oci:@(description=(address=(host=155.161.96.135)(protocol=tcp)(port=1521)) (connect_data=(sid=SCS)))", "scs", "password");


SessionFactory sessionFactory = new Configuration().buildSessionFactory();
Test1 test = new Test1();
test.setName("test");
Session session = sessionFactory.openSession(conn);
session.save(test);
}catch(Exception e){
e.printStackTrace();
}
}[/b]

I have put the Test1.hbm.xml and Test1.java class in the same folder.

When I run the program and try to insert new record into database
i got "no persister for:" error:

Help me please! i am stuck here for a whole day already :(

[b]Hibernate version:2.1[/b]



[b]Full stack trace of any exception that occurs:[/b]

[b]Name and version of the database you are using:[/b]

[b]The generated SQL (show_sql=true):[/b]

[b]Debug level Hibernate log excerpt:[/b]

it should look a bit like this :-



This needs to be in the root of your classpath, and list all the maping files. If this isn't the problem, then can you post your hibernate.cfg.xml please, and I'll have another look.

Chris

you also need to change your code slightly ...

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

Hi,

Thanks for you guys' help. It solve. I forgot to add the following codes in my calling class

new Configuration().addClass(XXXX.class)
new Configuration().setProperties(XXXXX.properties); //properties file

Thanks!
