I'm trying to generate database tables from annotated @entity classes for starters I'm just trying to generate anything:
1) I created a Derby database called DBtest.
2) I right clicked on the project and clicked 'new persistence
unit'
3) under 'Data source' I clicked 'New Datasource'
4) jndi name : jdbc/testDB
Database Connection url:
jdbc 
erby://localhost:1527/DBtest persistence.xml
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
<persistence-unit name="my_persistence_ctx">
<jta-data-source>jdbc/testDB</jta-data-source>
<properties>
<!--Use the java2db feature -->
<property name="toplink.ddl-generation" value="drop-and-create-tables"/>
<!-- Generate the sql specific to Derby database -->
<property name="toplink.platform.class.name"
value="oracle.toplink.essentials.platform.database.DerbyPlatform"/>
<property name="toplink.jdbc.user" value="test"/>
<property name="toplink.jdbc.password" value="test"/>
</properties>
</persistence-unit>
</persistence>

I have one entity class Person
/*

*/
package com.entity;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
/**

*/
@Entity
public class Person implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Override
public int hashCode() {
int hash = 0;
hash += (id != null ? id.hashCode() : 0);
return hash;
}
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Person)) {
return false;
}
Person other = (Person) object;
if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
return false;
}
return true;
}
@Override
public
String toString() {
return "com.entity.Person[id=" + id + "]";
}
}
---------------------------------------------------------------------------
I build and clean it, then deploy it to glassfish...and according to my understanding the table Person should be created...but nada
. It deploys fine without an exception, but no table is created. In fact, if i change the name inside <jta-data-source> to garbage there are still no exceptions, and it deploys fine...this leads me to believe the JNDI name is not registered properly in Glassfish. I'm not sure, but it is driving me nuts.
Any help would be GREATLY appreciated. Thanks!
