PLEASE HELP!!!! No recursion??????
I'm having a problem with a very simple mapping. I've went through all
the docs and examples, and afaik, the mappings are right. I'll provide
some context.
Database
========
create table LBRTRY_Q (UNQ_ID number(12) not null, MSG_TXT clob not /
null, STTS_CODE number(8) not null, NXT_UNQ_ID number(12));
alter table LBRTRY_Q add constraint LBRTRY_Q_PK primary key (UNQ_ID) /
using index;
create sequence LBRTRY_Q_SEQ maxvalue 999999999999 cycle;
Database And User Repositories
==============================
<jdbc-connection-descriptor
jcd-alias="default"
platform="Oracle9i"
jdbc-level="2.0"
driver="oracle.jdbc.driver.OracleDriver"
protocol="jdbc"
subprotocol="oracle:thin"
dbalias="@locahost:1521:iadb"
username="user1"
password="user1"
eager-release="false"
batch-mode="false"
useAutoCommit="0"
ignoreAutoCommitExceptions="false"
default-connection="true">
<sequence-manager
className="org.apache.ojb.broker.util.sequence.SequenceManagerNextValImpl"/>
</jdbc-connection-descriptor>
<class-descriptor
class="com.clrstream.chr.mm.persistence.HL7Message"
proxy="dynamic"
table="LBRTRY_Q">
<field-descriptor
name="id"
column="UNQ_ID"
jdbc-type="INTEGER"
primarykey="true"
autoincrement="true"
sequence-name="LBRTRY_Q_SEQ"/>
<field-descriptor
name="value"
column="MSG_TXT"
jdbc-type="VARCHAR"/>
<field-descriptor
name="status"
column="STTS_CODE"
jdbc-type="INTEGER"/>
<field-descriptor
name="nextId"
column="NXT_UNQ_ID"
jdbc-type="INTEGER"
access="anonymous"/>
<reference-descriptor
name="next"
class-ref="com.clrstream.chr.mm.persistence.HL7Message">
<foreignkey field-ref="nextId"/>
</reference-descriptor>
</class-descriptor>
Important Bits Of The Persistent Java POJO
==========================================
public class HL7Message
{
private static int UNPROCESSED = 67;
private static int MAX_LENGTH = 1
protected int id;
protected String value = null;
protected int status = UNPROCESSED;
protected HL7Message next;
public HL7Message()
{
}
public HL7Message(String value)
{
int messageLength = value.length();
if (messageLength > MAX_LENGTH)
{
this.value = value.substring(0, MAX_LENGTH);
this.next = new HL7Message(value.substring(MAX_LENGTH));
}
else
{
this.value = value;
}
}
}
Important Bit Of Unit Test
==========================
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
...
HL7Message msg = new HL7Message("123");
broker.beginTransaction();
broker.store(msg);
broker.commitTransaction();
Query query = new QueryByCriteria(HL7Message.class, null);
Collection results = broker.getCollectionByQuery(query);
assertTrue("Found 1 Message", results.size() == 1);
HL7Message foundMessage = (HL7Message) results.toArray()[0];
assertTrue("Recursively 3 deep", foundMessage.getNext().getNext() !=
null);
PROBLEM
=======
You can see that the table is simple a queue that breaks up a message
into 4k bits, actually for testing, simply string of length 1. When I
broker.store(), it only creates 1 record in the database. The WEIRD
part is that this test PASSES!! Looking at the database, it shouldn't.
Is there some kind of caching going on?

Need the auto-update to be "true" - off by default I guess
thanks for all who were beginning to try and help me

So that you can see a pattern, I've attached the database results after
I run the test 3 times.

One more thing...
One the one record in the database it does produce, the UNQ_ID = 1 and
the NXT_UNQ_ID = 2, just as expected, But, there's NO SECOND RECORD!
Very weird. Looks like the SequenceImpl correctly assigns the UNQ_ID
and understand the foreign key relationship just fine, but can't persist
the recursive behaviour.

BTW - on a subsequent test that does the query again, it fails. I does
only see the 1 record and doesn't build my linked list. Looks like
there is some caching. Anyone know what I'm doing wrong here or do we
just have a bug?
