Hi,
i want to store a class which extends an AbstractClass in two Tables.
For this, i tried it with the samle from apache.org.
If a make an Query for Class B, i get the object and the superfields where
filld.
But if i try to to store B the table A where not filled.
Can anyone help?
package de.intermediate.epic;
Class A:
===========================================
public class B extends A
{
int my_id; // id is the primary key
int ref_ID; // aID is the foreign key referencing
A.id
int someValueFromB; // mapped to a column in B_TABLE
public int getSomeValueFromB() { return someValueFromB; }
public void setSomeValueFromB(int someValueFromB) {
this.someValueFromB = someValueFromB; }
public int getMy_id() { return my_id; }
public void setMy_id(int my_id) { this.my_id = my_id; }
public int getRef_ID() { return ref_ID; }
public void setRef_ID(int ref_ID) { this.ref_ID = ref_ID; }
}
Class B:
===========================================
package de.intermediate.epic;
public class A
{
int ida; // primary key
int someValueFromA; // mapped to a column in A_TABLE
public int getSomeValueFromA() { return someValueFromA; }
public void setSomeValueFromA(int someValueFromA) { this.someValueFromA
= someValueFromA; }
public int getIda() { return ida; }
public void setIda(int ida) { this.ida = ida;}
}
