I have two problems. the first is simple:
org.apache.ojb.broker.accesslayer.CollectionProxy
does not appear in the API documentation at
http://db.apache.org/ojb/api/index.html, nor does anything else in
org.apache.ojb.broker.accesslayer.
The second is probably my misunderstanding the documentation, or a gap in
the documentation. I am trying to use a dynamic proxy in a 1:1 relation. I
know that this has very little point, but at the moment I am just
experimenting.
If in the reference-descriptor I have auto-retrieve="true" proxy="false"
then all is well.
If I have auto-retrieve="true" proxy="true" then when I try to use the
referenced value I get an error about unmaterialised proxy, even when I try
to access the referenced object through a method which is in the public
interface.
Here is the xml
<class-descriptor
class="com.gsk.bet.EntityPreferedName"
table="EntityPreferedName"
>
<field-descriptor
name="betid"
column="BETID"
jdbc-type="INTEGER"
primarykey="true"
autoincrement="false"
/>
[snip]
<reference-descriptor
name="bet"
class-ref="com.gsk.bet.Entity"
proxy="true"
auto-retrieve="true"
>
<foreignkey field-ref="betid"/>
</reference-descriptor>
</class-descriptor>
The Entity class has no foreign keys.
When I call EntityPreferedName.toString() I get
Class class com.gsk.bet.EntityPreferedName betid:1 preferedNameid:1
entryDate:2003-03-06 person:Hugh
unmaterialized proxy for com.gsk.bet.Entity{1}
The code looks like
public class EntityPreferedName {
protected int betid;
[snip]
protected EntityInterface bet;
public String toString()
{
return "Class "+getClass()+
" betid:" + String.valueOf(betid)+
" preferedNameid:" + String.valueOf(preferedNameid)+
" entryDate:" + entryDate +
" person:" + person +
"\n\t"+ getBet().toString();
}
/**
* @return
*/
public int getBetid() {
return betid;
}
/**
* @return
*/
public EntityInterface getBet() {
return bet;
}
/**
* @return
*/
public EntityName getPreferedAbbreviationName() {
return preferedAbbreviationName;
}
[snip]
}
public interface EntityInterface {
public String toString();
public int getBetid() ;
public String getDescriptor();
public String getEntityType();
public Date getEntryDate();
public String getPerson();
public void setBetid(int betid) ;
public void setDescriptor(String string);
public void setEntityType(String string) ;
public void setEntryDate(Date date) ;
public void setPerson(String string) ;
}
