***************************************************************************************************
I used the reverse engineering in Myeclipse to generate the POJOs and DAOs:
Here is the code for the findAll() in my DAO(I added this method):

public Products[] findAll() {
log.debug(“finding ALL Products “);
List products = new ArrayList();
try {
List results = getSession()
.createCriteria(“Products”)
.list();
log.debug(“find All products successful, result size: ” + results.size());
/** convert the List of objects to an ArrayList of Products objects */
for (Iterator iter = results.iterator(); iter.hasNext();) {
products.add((Products) iter.next());
}
/** convert the ArrayList to an Array of Products */
return (Products[]) products.toArray(new Products[0]);
} catch (RuntimeException re) {
log.error(“find All products failed”, re);
throw re;
}
}
**************************************************************************************************
The line in bold where i cast an iter.next() to my Products pojo is the culprit. Basically I can’t cast from an object class(iter.next() returns object) to my pojo named Products.
Here is my Products.java generated by reverse engineering tool:
***************************************************************************************************
package com.cyberize.hibernate3;
// Generated by MyEclipse – Hibernate Tools

import java.util.Date;
import java.util.Set;

/**

It seems that the POJOs are not subclass of object class .

Any help would be greatly appreciated.
Thank You

I would suggest setting a breakpoint and seeing what type of object iter is returning with the call to next()
