Hello,
When deploying Entity Bean (packaged in a ear archive with other components)
on BEA weblogic I'm getting the following message:
...<prim-key-class> must match the Class used by Primary Key Field get/set
Methods in the Bean Class....
I have following settings:
1. Oracle 8 database table's primary key: NUMBER NOT NULL
2. deployment descriptor: <prim-key-class>java.lang.Integer</prim-key-class>
3. get/set methods in Bean class:
public abstract int getOrderNumber();
public abstract void setOrderNumber(int orderNumber);
What is the cause for this problem above? I found this solution in
several books and tutorials! I wonder how this works?
When I change the abstract methods to:
public abstract java.lang.Integer getOrderNumber();
public abstract void setOrderNumber(java.lang.Integer orderNumber);
I'm able to deploy, but when running application I'm getting an error
message about incompatible types (int versus java.lang.Integer) as my Enity
Bean is receiving an int value created from an Oracle sequence "select
orderId.NEXTVAL from DUAL".
Extract from BEAN CLASS:
-----------------------------
// abstract methods
public abstract int getOrderNumber();
public abstract void setOrderNumber(int n);
//public abstract java.lang.Integer getOrderNumber();
//public abstract void setOrderNumber(java.lang.Integer n);
/* other abstract methods removed from this text file */
/* select methods removed from here for simplicity */
// contract methods
public Integer ejbCreate(int orderNumber, String orderCustomer) throws
CreateException {
setOrderNumber(orderNumber);
setOrderCustomer(orderCustomer);
return null;
}
Extract from HOME INTERFACE:
------------------------------------
public OrderMasterEB create(int orderNumber, String orderCustomer)
throws CreateException, RemoteException;
public OrderMasterEB findByPrimaryKey(Integer primaryKey)
throws RemoteException, FinderException;
The sequence is being called from a session bean, here is an extract:
---------------------------------------------------------------------
public int getOrderNumber() {
int orderNumber = 0;
.......
stmt.executeQuery("select orderId.NEXTVAL from DUAL");
resultSet = stmt.getResultSet();
if ((resultSet != null) && (resultSet.next())) {
orderNumber = resultSet.getInt(1);
}
..........
return orderNumber;
}
In the case I'll use java.lang.Integer instead of int, how can I match it to
the result set type? As I'll need to replace int by java.lang.Integer on
every reference of orderNumber somewhere in the code!?
Very grateful for any help!
Thanks in advance!
Best regards,
Wolf
