IllegarlArgumentException Error
You are right Andy, but I had probed every option with similar errors.
For instance when I selected PersistentFieldDirectAccessImpl this was
the console output.
[DEFAULT] ERROR: Error getting field:idAtributo in object:com.ecip.ojb.AtributoImpl
org.apache.ojb.broker.metadata.MetadataException: Error getting field:idAtributo in
object:com.ecip.ojb.AtributoImpl
at
org.apache.ojb.broker.metadata.fieldaccess.PersistentFieldDirectAccessImpl.doGet(Unknown
Source)
at
org.apache.ojb.broker.metadata.fieldaccess.AbstractPersistentField.get(Unknown Source)
at org.apache.ojb.broker.query.QueryByCriteria.buildCriteria(Unknown Source)
This is the class, it have private fields and public getters and setters.
I thought that PersistentFieldIntrospectorImpl option was right.
package com.ecip.ojb;
public class AtributoImpl implements Atributo, java.io.Serializable {
private Integer idAtributo;
private String atributo;
private String descripcion;
public Integer getIdAtributo() {
return idAtributo;
}
public String getAtributo() {
return atributo;
}
public String getDescripcion() {
return descripcion;
}
public void setIdAtributo(Integer id) {
this.idAtributo = id;
}
public void setAtributo(String atrib) {
this.atributo = atrib;
}
public void setDescripcion(String descrip) {
this.descripcion = descrip;
}
}
Is this class OK?
What else should I check in the ojb properties file?
Thanks Andy.

Check your OJB.properties (PersistentFieldClass). You seems to be using
PersistentFieldIntrospectorImpl which require
JavaBeans-style getters and setters.

Re: FW: How to set null for a column for which the corresponding java type is long
Thanks a lot for all of your answers. I just realized
that OJB can convert from JDBC types to Number
(Integer, Long, BigInteger,BigDecimal) automatically.
For example, JDBC type BIGINT can be converted to
either primitive long or Object Long without any
FieldConversion. In this case, I can just use Long
instead of long to solve the problem.
Just wondering anybody can update the document
http://db.apache.org/ojb/jdbc-types.html to make that
explicit?
Thanks,
Zhe

Re: FW: setStartAtIndex/setEndAtIndex for a very large result set
After more investigation by looking into OJB code, I found that the out of memory problem occurs in org.apache.ojb.broker.accesslayer.RsIterator.size() method. In that method, there are two ways to get size: 1) count 2) .last .getRow I found that 2) will give me out of memory error.I tried that with pure JDBC and also got out of memory error. However, if I force to use 1), it works fine. I am using Oracle 9i. I am worndering whether there is any way to solve this problem. Currently I have to set jdbc-level="1.0" instead of "2.0" to force 1) is used.

However, the OJB sequence seems to assume the field MAX_KEY is an integer, and therefore throws a Numeric Overflow SQLException as seen in the traces below. Is this a problem for anyone else and has a fix been discussed? I think it's a bug in repository_internal.xml. We declare MAX_KEY as Integer, but it should be BIGINT. Does changing of column type for MAX_KEY solve your problem? regards, Armin In the logs below i found it interesting that that ojb seems to be looking for a Long: at org.apache.ojb.broker.util.sequence.SequenceManagerHighLowImpl.getUniqueLong(SequenceManagerHighLowImpl.java:191) but the Oracle call seems to be looking for an Int: at oracle.jdbc.driver.OracleResultSet.getInt(OracleResultSet.java:1551) [Full Exception Trace]: 1075770103075|0|1|statement|SELECT A0.MAX_KEY,A0.TABLENAME,A0.GRAB_SIZE,A0.VERSION,A0.FIELDNAME FROM OJB_HL_SEQ A0 WHERE (A0.TABLENAME LIKE ? ) AND A0.FIELDNAME LIKE ? |SELECT A0.MAX_KEY,A0.TABLENAM E,A0.GRAB_SIZE,A0.VERSION,A0.FIELDNAME FROM OJB_HL_SEQ A0 WHERE (A0.TABLENAME LIKE 'SEQ_TRK_CASE' ) AND A0.FIELDNAME LIKE 'ID' java.sql.SQLException: Numeric Overflow at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:180) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:222) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:285) at oracle.jdbc.driver.OracleStatement.getIntValue(OracleStatement.java:3677) at oracle.jdbc.driver.OracleResultSetImpl.getInt(OracleResultSetImpl.java:332) at oracle.jdbc.driver.OracleResultSet.getInt(OracleResultSet.java:1551) at com.p6spy.engine.spy.P6ResultSet.getInt(P6ResultSet.java:261) at org.apache.ojb.broker.util.SqlTypeHelper.getObjectFromColumn(SqlTypeHelper.java:573) at org.apache.ojb.broker.util.SqlTypeHelper.getObjectFromColumn(SqlTypeHelper.java:328) at org.apache.ojb.broker.util.SqlHelper.getObjectFromColumn(SqlHelper.java:169) ... rethrown as org.apache.ojb.broker.PersistenceBrokerException: Error reading class type: org.apache.ojb.broker.util.sequence.HighLowSequence from result set: Numeric Overflow at org.apache.ojb.broker.accesslayer.RowReaderDefaultImpl.readObjectArrayFrom(RowReaderDefaultImpl.java:171) at org.apache.ojb.broker.accesslayer.RsIterator.getObjectFromResultSet(RsIterator.java:426) at org.apache.ojb.broker.accesslayer.RsIterator.next(RsIterator.java:263) at org.apache.ojb.broker.core.PersistenceBrokerImpl.getCollectionByQuery(PersistenceBrokerImpl.java:1403) at org.apache.ojb.broker.core.PersistenceBrokerImpl.getCollectionByQuery(PersistenceBrokerImpl.java:1563) at org.apache.ojb.broker.core.PersistenceBrokerImpl.getCollectionByQuery(PersistenceBrokerImpl.java:1599) at org.apache.ojb.broker.core.PersistenceBrokerImpl.getCollectionByQuery(PersistenceBrokerImpl.java:1588) at org.apache.ojb.broker.core.PersistenceBrokerImpl.getObjectByQuery(PersistenceBrokerImpl.java:1856) at org.apache.ojb.broker.core.DelegatingPersistenceBroker.getObjectByQuery(DelegatingPersistenceBroker.java:291) at org.apache.ojb.broker.core.DelegatingPersistenceBroker.getObjectByQuery(DelegatingPersistenceBroker.java:291) at org.apache.ojb.broker.util.sequence.SequenceManagerHighLowImpl.getSequence(SequenceManagerHighLowImpl.java:251) at org.apache.ojb.broker.util.sequence.SequenceManagerHighLowImpl.getUniqueLong(SequenceManagerHighLowImpl.java:191) at org.apache.ojb.broker.util.sequence.AbstractSequenceManager.getUniqueValue(AbstractSequenceManager.java:125) at org.apache.ojb.broker.util.BrokerHelper.getAutoIncrementValue(BrokerHelper.java:303) at org.apache.ojb.broker.util.BrokerHelper.getValuesForObject(BrokerHelper.java:349) at org.apache.ojb.broker.util.BrokerHelper.getKeyValues(BrokerHelper.java:215) at org.apache.ojb.broker.Identity.init(Identity.java:165) at org.apache.ojb.broker.Identity.(Identity.java:129) ... 1075770103125|0|1|rollback|| 1075770103125|0|0|rollback|| ERROR 2004-02-02 20:01:43,125 [EMAIL PROTECTED]:org.apache.ojb.broker.metadata.ClassNotPersistenceCapableException: Can not init Identity for given object beans.CaseBean: Could not obtain next object: Error reading class type: org.apache.ojb.broker.util.sequence.HighLowSequence from result set: Numeric Overflow Regards, Phil Armour - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail

Check your OJB.properties (PersistentFieldClass).

You use the same configuration as a single as in the Clustering documentation, but just comment out the two lines: cache.event.listeners=com.opensymphony.oscache.plugins. clustersupport.JavaGroupsBroadcastingListener AND cache.cluster.multicast.ip=231.12.21.132 This will create OSCache in single environment without multicast distribution.

The reason is I personal only use the src-version, thus I don't know

Several ant targets only run with the src-dist. Only src-dist contains

hmm, I don't think so. There was a bug when equals

How does the generated sql look like? You can use
p6spy to log all
generated SQL. If you run your test within
OJB-suite
you only need to
enable p6spy in build.properties file.

Subject: Stored Procedure / returning primary key
Gurus,
I try to use a stored procedure to insert a table. This works perfectly. The
stored procedure does correctly return the values that get inserted into the
database.
Unfortunately, the object I am inserting does not change after the insert
(toString() before and after). Can you please point out what I am doing
wrong?
Any help is greatly appreciated!
The repository_user.xml:
The Java code tested (Persistence Broker API):
PersistenceBroker broker = null;
try
{
broker =
PersistenceBrokerFactory.defaultPersistenceBroker();
broker.beginTransaction();
broker.store(ztb);
broker.commitTransaction();
}
finally
{
if (broker != null) broker.close();
}
ODMG API:
// Implementation odmg = OJB.getInstance();
// Database db = odmg.newDatabase();
// try {
//
// db.open("TABI",
Database.OPEN_READ_WRITE);
// } catch (Exception e) {
//System.out.println(e.toString());
// }
//
// TransactionExt tx = (TransactionExt) odmg.newTransaction();
// System.out.println("vor insertf: " + ztb.toString());
//
// tx.begin();
// tx.markDirty(ztb);
// tx.commit();
Thank you very much!!
Cheers,
Chris

oracle and dates
Datebase: Oracle 8.1.7.4 or Oracle 9.2.0.4 OJB Version:1.0rc5 I'm having problems trying to do a search something like this: select * from foobar where date1 >= sysdate and date1 <= sysdate +1 I've tried using the greaterThan and lessThan methods on criteria but I get an "invalid column error" from Oracle. I thought that perhaps the parameters weren't getting bound to the PreparedStatement properly, but I think I've been able to rule that out. It appears that it's failing in the setObject method of the Oracle driver. I've tried to modify the setObjectForStatement but for some reason it's still using the setObject. I then looked at the list archives and found something about using addSql, so I tried that. That gave me StringOutOfBounds(-2) exceptions, with the criteria display showing that the I added looked to be added twice with a "null" at the end of the string (looks like this "null"). So I've been looking at the source for the addSql method which seems to create a SqlCriteria, all of which looks ok to me. My guess is that the SQL generator is getting confused or something. I then tried setting up the criteria for the date ranges as separate criteria. I added the second criteria to the first as an addAndCriteria, but instead of having just one of the "null"'s I ended up with two of them. Anyway what I'm looking for is someone who can give me a clue of another way to make this work. Or suggest somewhere in the code that I haven't looked at yet to fix. I'll happily upload the repository.xml and the code that calls OJB if need be. --mikej -=-- mike jackson [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Broker Critera Negation weirdness
Hi,
I've discovered some odd behavior exhibited by the broker criteria API
and I was wondering if anyone had come across this.
My system is dynamically building complex queries by building criteria
objects one at a time and then pulling them together with addAndCriteria
and addOr Criteria.
So my code looks something like this pseudocode:
Criteria criteria = new Criteria(); // create criteria object
while (myQuery.hasMoreElements()) {
Criteria c1 = new Criteria(); // new criteria
newCrit.addEqualTo("myProperty", myValue);
if (myNegation) {
c1.setNegative(true);
}
criteria.addAndCriteria(c1);
}
So this code loops through some objects that I've created and adds a
number of criteria to a central criteria object. Each criteria may be
negated.
My problem is that on the first call to addAndCriteria, a Criteria
object is not added to my main criteria, only a ValueCriteria.
So say I want to do:
WHERE (NOT forename=brendan) AND (NOT surname IS NULL)
My code would loop twice setting values and setNegative(true) for each
sub-criteria.
Looking at my final criteria object via getElements and printing the
types
Using this code (with Logger being a simple class that writes output to
a file):
Enumeration critElements = criteria.getElements();
while (critElements.hasMoreElements()) {
Object testCrit = critElements.nextElement();
Logger.debugLog("type "+testCrit.getClass().getName());
if (testCrit instanceof Criteria) {
Criteria tc = (Criteria) testCrit;
if (tc.isNegative()) {
Logger.debugLog("Criteria is negative");
}
}
}
I get the following result in my logfile:
type org.apache.ojb.broker.query.ValueCriteria
type org.apache.ojb.broker.query.Criteria
Criteria is negative
Using criteria.toString() I get:
[forename = brendan, [surname IS NULL ]]
What this means is that I have completely LOST the isNegative value for
the first criteria I add. The containing criteria object is not negative
(I don't want it to be either I want to control the negativity of each
criteria I add).
Why does criteria.addAndCriteria convert a Criteria to ValueCriteria
when adding the first criteria losing the negative switch?
What I'd expect to see from criteria.toString() after the above code is:
[[forername = brendan], [surname IS NULL ]] - with both elements being
instances of Criteria.
Subsequent calls to addAndCriteria() after the first add Criteria
objects as you would expect.
[ forname=brendan, [surname IS NULL], [email IS NULL] ]
There is a simple dodgy workaround I could do where the first criteria I
add always evaluates to TRUE but this is far from ideal.
Any Ideas?
Cheers,
Brendan.

Anonymous Keys Warning, was Re: Installation of OJB
Hmm, what I get for writing docs without stepping through code
carefully enough.
Armin has pointed out that using anonymous keys for PK's is going to
bomb if used in a clustered environment (or anywhere that persistent
objects are serialized and migrated) and he is completely correct!
Anyone using them as I documented in the HOWTO be warned =) I will fix
the howto asap, but for personal reasons... that may not be as soon as
I like =/

Hi Armin,
thanks for your patience, first!
but the things with declaring PK_Fields
i read at:
http://db.apache.org/ojb/howto-use-anonymous-keys.html
i did everything like told me :-)
the document is written nice and understandful,
doh! Assume the current implementation doesn't
achieve this. All anonymous keys are held in an internal map using
the
object itself as key. Reading will be successful, but when the object
e.g. will be serialized and then returned to OJB the anonymous PK
field will never be found (object does not match a key), its only
possible to extract the FK from the associated reference object.
Thus I think anonymous keys will only work in
conjunction with 1:1 references.
I don't write the 'anonymous-key' stuff, so maybe I
overlooked an important argument.
regards,
Armin
but only the little thing froeign-key is null in my case...
did you know if this sample is available?
i didn´t found it in src-distribution.
thanks alot!

Hi
Ralf,
but in my case the own id´s
of a class where anonymous too,
is that the matter?
AFAIK we don't have a test case that mix this
stuff.
Think it is not allowed to declare a PK field
anonymous.
Recommend you to setup a test case similar to the
examples in test suite or docu
(http://db.apache.org/ojb/tutorial3.html#Mapping
1:1
associations). As recently as your test pass start
to tweak ;-)

patch for org.apache.ojb.broker.util.SqlHelper class
I recently upgraded from 1.0.rc4 to 1.0.rc5. This broke some code I had
written that used the method
org.apache.ojb.broker.query.Criteria.addSql(String). The SQL I added was
of the form: soundex(value) = soundex(column). This resulted in an
java.lang.ArrayIndexOutOfBoundsException being thrown by the
org.apache.ojb.broker.util.SqlHelper.splitPath(String) method because
the braceBegin variable was greater than the braceEnd variable. In
addition to the check that both braceEnd and braceBegin are at least
zero, there should be a check that braceEnd is, in fact, bigger than
braceBegin.
The patch is below.
Thanks
Andrew

RE: Installation of OJB
This has brought up an interesting question for me.
I am NOT using any anonymous keys, but i like the principle of them.
The majority of my work is web-based. Therefore, by not having PKIDs it's
much harder to pass references between requests.
Does anyone have any simple solutions to this problem?
My solution was to store the objects in a hashmap in the session, then pass
the key through html requests.
However, this does make transactions more painful, and it means that you are
storing the retrieved persistant object (whole tree if not proxied) in the
session until it is removed or until the session expires. This can use a
lot of memory.
I've found it a much cleaner approach in web apps to use ids. Provide a
service that hands out objects referenced by id or lists of objects when
requested (ie getPerson(int id)) and updates objects using the new data (not
objects) and an id (eg updatePerson(int personId, String newName, String
newJobTitle,...)).
Any thoughts?
Daniel.

Re: Installation of OJB
Hi Ralf,
hmm, your test is now similar to the tests in OJB test-suite. These
tests pass without problems (against hsql, sapDB, mySQL,...).
How does the generated sql look like? You can use p6spy to log all
generated SQL. If you run your test within OJB-suite you only need to
enable p6spy in build.properties file.

Memory problems using default cache
When using the default cache implementation, i run out of memory when performing a great amount of object storings with ojb. I saw a post some weeks ago saying that someone ran into the same problem. An idea was that the cache keys were not garbaged, even if objects were (via SoftReference). I also saw that there was an implementation of a LRU cache that was begun (ObjectCacheSoftImpl). I added the right constructor to it, and used it. It seems to work great. So my question is: will this ObjectCacheSoftImpl class will be supported, or should i continue to use my own derived implementation ?

hi brain, an example would be nice, i know, that i can not access an anonymous-key in java :-) the reason why i find this useful is, because of having clean JavaBeans for database. not blown up with eg carId (when i am also reffering to a car) but armin told, that anonymous-keys not available in 1.0.rc5..? now i am really confused :-) greetings ralf --- Brian McCallister <[EMAIL PROTECTED]> schrieb: > I declare PK's anonymous quite frequently.

Hi Ralf,
it does deal with anonymous fields, but only in conjunction with 1:1
references. Please post class-descriptor and source for Customer, Car.

i did everything like told me :-)
the document is written nice and understandful,
doh! Assume the current implementation doesn't
achieve this. All
anonymous keys are held in an internal map using the
object itself as
key. Reading will be successful, but when the object
e.g. will be
serialized and then returned to OJB the anonymous PK
field will never be
found (object does not match a key), its only
possible to extract the FK
from the associated reference object.
Thus I think anonymous keys will only work in
conjunction with 1:1
references.
I don't write the 'anonymous-key' stuff, so maybe I
overlooked an
important argument.

but only the little thing
froeign-key is null in my case...
did you know if this sample is available?

Recommend you to setup a test case similar to the

This
*can* actually be
done in the OTM if Car is a truly dependent

made
explicitly persistent.

Hi Ralf, > but in my case the own id´s > of a class where anonymous too, > is that the matter? AFAIK we don't have a test case that mix this stuff. Think it is not allowed to declare a PK field anonymous.

RE: Problem updating objects with collections
I found a workaround, but i will decrease performance dramatically. Instead of doing a broker.store(a); I do the following: Identity id = new Identity(a, broker); A oldA = broker.getObjectByIdentity(id); broker.delete(oldA); broker.store(a); If i usie only the store call (which leads to data inconsistency) the sql statements executed are the following ones: update a ...// update object a insert into b ... // store b collection, without removing old ones... When using the workaround, the following statements are executed: delete from b ... // delete collection of B delete from a // delete object A select ... from a // the object is not in cache anymore, so materialize it insert into a ... // insert a select ... from b // check materializing b insert into b ... // insert into b Which is not optimal at all. I'd like to have the following statement: delete from b ... // remove old collection of b update a ...// update object a insert into b ... // insert new collection Can anyone give me a hint the problem ? -Message d'origine- De : Guillaume Nodet [mailto:[EMAIL PROTECTED] Envoye : mardi 3 fevrier 2004 10:12 A : OJB Users List Objet : Problem updating objects with collections Here is my problem: I've got an object of class A with a collection of objects of class B.

Re: ojb with Sybase
Hi,
we are successfully using Sybase with PersistenceBroker (no ODMG)
however this shouldn't be a problem.
depending on your Sybase version you should try to use
platform="SybaseASE" instead of "Sybase" in your connection descriptor.
this solved our problems (we also were using platform="Sybase" at the
beginning)
bye

Hi, I tried to use ojb with Sybase, it did not work.
but the same code worked fine with mysql and sql server.
I wanted to do an easy retrieve from the Sybase,I met an Exception that
is "[org.apache.ojb.odmg.collections.DListImpl] ERROR: Generation of new
id failed

Here is my code,xml and Exception , anyone can give me some clue to
solve this problem which puzzle me two days.
CODE:
public static List retrieveBook(String bookName){
Implementation impl = OJB.getInstance();
Database db=impl.newDatabase();
try {
db.open("webpublishSybase",db.OPEN_READ_ONLY);
} catch (ODMGException e) {
e.printStackTrace(); //To change body of catch statement use
Options | File Templates.
}
List list=null;
Transaction tx = impl.newTransaction();
try{
tx.begin();
OQLQuery query = impl.newOQLQuery();
query.create("select results from "+Book.class.getName()+"
where bookName like $1 ");
query.bind(bookName);
DList results = (DList) query.execute();
tx.commit();
list=results;
}catch(Exception e){
e.printStackTrace();
tx.abort();
}finally{
try {
db.close();
} catch (ODMGException e) {
e.printStackTrace(); //To change body of catch statement
use Options | File Templates.
}
}
