Hi Armin:
Because I deploy OJB to JBoss, my application must run on JBoss. Its
test case must also deployed to JBoss.
I can post the two simple class ,Person and Project calss, if these are
useless to debug. It doesn't matter. I will give this solution.
<!-------------------------------------------------------------Person
class----------------------------------------------------->
package com.dsc.nana.domain.organization;
import java.util.*;
public class Person{
private String OID;
public String getOID(){
this.OID;
}
public void setOID(String pNewValue){
this.OID= pNewValue;
}
/** name of person*/
private String name = null;
/** name's getter
* @author Dogie Tsai
* @since 2002/10/22
*/
public String getName() {
return this.name;
}
/** name's setter
* @author Dogie Tsai
* @since 2002/10/22
*/
public void setName(String pNewValue) {
this.name = pNewValue;
}
/** OID of the project that person join */
private String containerOID = null;
/** containOID's getter
* @author Dogie Tsai
* @since 2002/10/22
*/
public String getContainerOID() {
return this.containerOID;
}
/** containOID's setter
* @author Dogie Tsai
* @since 2002/10/22
*/
public void setContainerOID(String pNewValue) {
this.containerOID = pNewValue;
}
/** the project that person join */
private Project container = null;
/** container's getter
* @author Dogie Tsai
* @since 2002/10/22
*/
public Project getContainer() {
return this.container;
}
/** container's setter
* @author Dogie Tsai
* @since 2002/10/22
*/
public void setContainer(Project pNewValue) {
this.container = pNewValue;
pNewValue.addPerson(this);
}
public Person() {
}
}
<!-----------------------------------------Project--------------------------
------------------------->
package com.dsc.nana.domain.organization;
import com.dsc.nana.persistence.PersistentObject;
import java.util.*;
import org.odmg.DMap;
import org.apache.ojb.odmg.collections.DMapImpl;
public class Project{
private String OID;
public String getOID(){
this.OID;
}
public void setOID(String pNewValue){
this.OID= pNewValue;
}
private String name = null;
/** name's getter
* @author Dogie Tsai
* @since 2002/10/22
*/
public String getName() {
return this.name;
}
/** name's setter
* @author Dogie Tsai
* @since 2002/10/22
*/
public void setName(String pNewValue) {
this.name = pNewValue;
}
private DMap persons;
public DMap getPersons(){
if (this.persons == null){
this.persons = new PersonMap ();
}
return this.persons ;
}
public void setPersons(DMap pNewValue){
this.persons = pNewValue;
}
public void addPerson(Person pMember){
if (this.getPersons().containsValue(pMember)){
} else {
this.getPersons().put(pMember.getOID() ,pMember);
pMember.setContainer(this);
}
}
public Project() {
}
}
I just new a project and a person.The Person add in the project. Then store
project.
