I have a similar problem. CRUD generation on my POJOs results in the same
error and stacktrace as yours. However, if I copy/paste my POJOs in a
project created from scratch, CRUD generation works fine!
NB: both projects went through appfuse:full-source and hibernate3:hbm2ddl
before running appfuse:gen.
Here's my POJO and stacktrace:
=========================
package fr.crb.gast.model;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity @Table(name="DCP_DELIBCP")
public class DelibCP extends BaseObject {
@Id @GeneratedValue @Column(name="DCP_IDENT")
private Long id;
@Column(name="DCP_DTDELIB", nullable=false)
private Date dateDelib;
@Column(name="DCP_NUMERODELIB", nullable=false, unique=true)
private Integer numeroDelib;
//START GETTERS AND SETTERS
public Date getDateDelib() {
return dateDelib;
}
public void setDateDelib(Date dateDelib) {
this.dateDelib = dateDelib;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Integer getNumeroDelib() {
return numeroDelib;
}
public void setNumeroDelib(Integer numeroDelib) {
this.numeroDelib = numeroDelib;
}
//STOP GETTERS AND SETTERS
/* (non-Javadoc)
* @see fr.crb.gast.model.BaseObject#equals(java.lang.Object)
*/
@Override
public boolean equals(Object o) {
// TODO Auto-generated method stub
return false;
}
/* (non-Javadoc)
* @see fr.crb.gast.model.BaseObject#hashCode()
*/
@Override
public int hashCode() {
// TODO Auto-generated method stub
return 0;
}
/* (non-Javadoc)

*/
@Override
public String toString() {
// TODO Auto-generated method stub
return null;
}
}
