Hi!
At first I�m sorry because my english level isn�t very good.
I�m working with J2SDKEE1.2.1. and I�ve problems with CMP and Windows 2000.
I�ve a EJB(CPersonaEJB,CPersonaHome,CPersona,CPersonaPK=EntityBean
class,interface home,interface remote,Primary key class).My primary key
field is an int.In the Application Deployment Tool running the new
Enterprise Bean Wizard I enter in the primary key class field:CPersonaPK;
and in the primary key Field Name field I select id_contperson.
When I run a client we have 2 problems with the methods :findByPrimaryKey
and getPrimaryKey.
With findByPrimaryKey I get the next messages:
javax.ejb.FinderException: ERROR in database SELECT for
find:java.sql.SQLException: Invalid column type:setObject
Whit getPrimaryKey I get the next messages:
When I try to convert the object returned by the method getPrimaryKey into
CPersonaPK Class, I can�t because there is the nest Exception:
java.lang.ClassException
My code is:
<<CPersonaPK>>:
public class CPersonaPK implements java.io.Serializable {
public int id_contperson;
public CPersonaPK(){}
public int hashCode() {
return id_contperson;
}
public boolean equals(Object obj) {
if(obj == null || !(obj instanceof CPersonaPK))
return false;
else if (((CPersonaPK)obj).id_contperson==id_contperson)
return true;
else
return false;
}
}
