Re: Problem in PersistenceBrokerImpl
Hi Edson,
it's strange. I can find two places in code using
getCollectionIterator(...), but can't figure out where the NPE was could
be thrown.
In PB.deleteCollections(...) a 'null' check is done (line 623).
In PB.storeCollections(...) it is possible that null could be passed
(line 862), but if we return null in getCollectionIterator will end up
with a NPE.
Maybe I'm overlooked something. Could shed light on this?
regards,
Armin

Hi!
I've found a little bug in PersistenceBrokerImpl (latest CVS - downloaded 10
min ago), that can cause a NPE when storing:
private Iterator getCollectionIterator(CollectionDescriptor cds, Object
collectionOrArray)
{
Iterator colIterator;
if (collectionOrArray instanceof ManageableCollection)
{
colIterator = ((ManageableCollection)
collectionOrArray).ojbIterator();
}
else if (collectionOrArray instanceof Collection)
{
colIterator = ((Collection) collectionOrArray).iterator();
}
else if (collectionOrArray.getClass().isArray())
{
colIterator = new ArrayIterator(collectionOrArray);
}
else
{
String fieldName =
cds.getClassDescriptor().getClassNameOfObject() + "." +
cds.getAttributeName();
throw new OJBRuntimeException(
"Field '"
+ fieldName
+ "' "
+ collectionOrArray.getClass()
+ " can not be managed by OJB. Use Array, Collection or
ManageableCollection instead !");
}
return colIterator;
}
The problem occur when collectionOrArray is null. I'm trying to put a test
like:
if(collectionOrArray==null) {
return null;
}
as solution. I'll let you know if this solves.
Thanks,
Edson Richter

this could happen the first time a sequence was used, e.g.

Primary Key from Insert-Round 2
Armin, you are correct. The same connection object is being used by the
insert and the PK query. I went back to my test app, closing the statement
for the insert before creating a new statement for the PK query, and it
worked there. However, the problem remains in OJB: the PK query returns
nothing.
FYI, I am now on OJB 1.5. Am having to run with compiled source since the
Jakarta version is not debug enabled.
Let me focus precisely on the problem. I have modified
JdbcAccessImpl.executeInsert() to include the statements needed to retrieve
the PK from the insert. I know it works because I've executed it with test
code without OJB. This code is for my own testing purposes and once I have
solved the problem, I will revert to the release version JAR files.
Here's the function as I'm testing it. Note the statements under
harvestReturnValues() are the test code as would be executed by
SequenceManagerNativeImpl. The ResultSet contains null.
public void executeInsert(ClassDescriptor cld, Object obj) throws
PersistenceBrokerException
{
if(logger.isDebugEnabled()) logger.safeDebug("executeInsert", obj);
PreparedStatement stmt = null;
try
{
stmt = broker.serviceStatementManager().getInsertStatement(cld);
if (stmt == null)
{
logger.error("getInsertStatement returned a null
statement");
throw new PersistenceBrokerException("getInsertStatement
returned a null statement");
}
broker.serviceStatementManager().bindInsert(stmt, cld, obj);
if (logger.isDebugEnabled())
logger.debug("executeInsert: " + stmt);
stmt.executeUpdate();
// Harvest any return values.
harvestReturnValues(cld.getInsertProcedure(), obj, stmt);
// This is the code that returns null for the PK. Works in test
system, not with OJB.
Connection connection = stmt.getConnection();
stmt.close();
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery("SELECT
SCOPE_IDENTITY()");
while (rs.next())
{
long val = rs.getLong(1);
System.out.println("PK=" + val);
}
}
catch (PersistenceBrokerException e)
{
logger.error(
"PersistenceBrokerException during the execution of the
insert: " + e.getMessage(),
e);
throw e;
}
catch (SQLException e)
{
logger.error(
"SQLException during the execution of the insert (for a "
+ cld.getClassOfObject().getName()
+ "): "
+ e.getMessage(),
e);

if (SQL_STATE_KEY_VIOLATED.equals(e.getSQLState()))
{
throw new KeyConstraintViolatedException(e);
}
else
{
throw new PersistenceBrokerSQLException(e);
}
}
finally
{
broker.serviceStatementManager().closeResources(stmt, null);
}
}
I'm now wondering if my problem is related to how the connection is
configured. I've played with a few settings, but maybe someone else would
catch it.

Re: Object not PersistenceCapable error
This usually happens if you are running against a class file (bytecode) that was not enhanced via the JDO bytecode enhancer. I suspect that the enhancer wasn't run, or there is a problem in the .jdo files for that class. -Brian On Mar 23, 2004, at 10:01 AM, Philippe Guillard wrote: I've got a JDOUserException/Object not PersistenceCapable error, Can somebody tell me in which direction i should look for my error?

Packed Field (DB2/400) Mapping
Hello, I am having a problem with OJB mapping of DB2/400 Packed Field. I mapped Packed Field in DB2/400 to DECIMAL with Java type BigDecimal. When I read records from database, it is fine. But when I try to update the record using OJB, it generates a SQL with that Packed Filed as null value. For example. I have a BigDecimal aField = 12345, but in SQL, 1080015521538|1222|0|statement|UPDATE CRPIBMS SET MSACFL=?,MSCHBY=?,MSCHDT=?,MSCHTM=?,MSDADM=?,MSDATE=?,MSDATT=?,MSDBY=?,MSDCNS=?,MSDDT=?,MSDFAM=?,MSDORD=?,MSDREF=?,MSDRL1=?,MSDRL2=?,MSDRL3=?,MSDTM=?,MSFLG1=?,MSFLG2=?,MSFLG3=?,MSFROM=?,MSACC2=?,MSACCT=?,MSEPIS=?,MSFCID=?,MSUREF=?,MSRSTS=?,MSSTFL=?,MSSTS=?,MSTEXT=?,MSTIME=?,MSTO=?,MSTYPE=?,MSVBY=?,MSVDT=?,MSVTM=?

Actually, it should be MSACC2='12345'. This cause SQL exception that this colume does not allow null value. Thank you for your help!
RE: soft-deleting objects
I am using this in a complex app (due to idiot admin users deleting stuff they shouldnt!). All objects have a boolean (mapped to int) "deleted". For all queries i look for objects with deleted=false. For relationships, i wrote a querycustomizer which adds deleted=false to collections. (see below example) It;s very simple and works a treat! If you have a 'base' bean, which all other beans inherit, you can put the 'deleted' attribute there, and can use a delete method for deleting any beans! (note: i dont use extents for this in the repository, just map it for all beans) -Original Message- From: Brian McCallister [mailto:[EMAIL PROTECTED] Sent: 23 March 2004 14:01 To: OJB Users List Subject: Re: soft-deleting objects If you have a "deleted" style flag in the database for the soft delete you can probably accomplish this via a query customizer.

RE: soft-deleting objects
I have implemented the very same thing via a custom RowReader. I just extended the
default RowReader, and read in the value from that super. After that, I just my
criteria to see if I should avoid it, and return based on that.
Here is my method that I implemnted that extended RowReaderDefaultImpl
public Object readObjectFrom(Map row) throws PersistenceBrokerException
{
Object o = super.readObjectFrom(row);
if (o instanceof AuditableBusinessObject)
{
if (((AuditableBusinessObject)o).getDeletedDate() != null)
return null;
}
return o;
}
Hope this helps.

Subject: soft-deleting objects
Hi,
I want to implement something like a soft-delete:
Objects should be marked as "deleted" in its corresponing table and OJB should just
ignore them when it is materializing or querying them.
Where would be the best point to start when I want to implement this feature? I just
played around with the RowReader-Concept - but I have the feeling that this is not the
right place to start, because I think I have to modify the queries OJB is submitting
to the database.
Any ideas?
Regards
Tino

Strange behaviour: Oracle sequence.nextval
Hi,
I am using OJB 1.0rc5 with Oracle8. When I try to store a simple object, the following
SQL queries are executed (p6spy.log):
1080045456718|15|0|statement||select TURBINE_USER_SEQ.nextval from dual
1080045456843|0|0|statement|SELECT
LAST_NAME,LOGIN_NAME,FIRST_NAME,USER_ID,PASSWORD_VALUE,EMAIL FROM TURBINE_USER WHERE
USER_ID = ? |SELECT LAST_NAME,LOGIN_NAME,FIRST_NAME,USER_ID,PASSWORD_VALUE,EMAIL FROM
TURBINE_USER WHERE USER_ID = '40049'
1080045456859|16|0|statement||select TURBINE_USER_SEQ.nextval from dual
1080045457265|406|0|statement|INSERT INTO TURBINE_USER
(USER_ID,EMAIL,FIRST_NAME,LAST_NAME,LOGIN_NAME,PASSWORD_VALUE) VALUES (?,?,?,?,?,?)
|INSERT INTO TURBINE_USER
(USER_ID,EMAIL,FIRST_NAME,LAST_NAME,LOGIN_NAME,PASSWORD_VALUE) VALUES
('40050','','Klaus','Richarz','neu01','BxlwjRzIFIOb2Bj9wn1EZlLw')
Why is "select TURBINE_USER_SEQ.nextval from dual" executed two times ?
