you should use the validationQuery attribute on the jdbc-connection

PATCH: Can't recreate previously deleted object
I am using rc3, ODMG.
I have encountered the following incorrect behavior:
tx {
Retrieve Role{1}
}
tx {
Delete Role{1}
role = new Role{2}
lock role
}
tx {
Delete Role{2}
role = new Role{1}
lock role
}
Role{1} is not inserted into the db in the final transaction. According to the
log, Role{1} gets registered with StateOldClean, which is incorrect.
Here is my analysis:
(1) ObjectEnvelope.setInitialModificationState() has this code:
if (LoadedObjectsRegistry.isRegistered(myObj))
{
initialState = org.apache.ojb.odmg.states.StateOldClean.getInstance();
}
That is, when an object is registered with a tx, if it has been seen before
then it is always registered as StateOldClean. I think that theoretically
"seen before" means "seen in a currently running PB transaction", but I'm not
certain of this.
(2) LoadedObjectsRegistry has the following comment:
Note: objects remain registered even after they are deleted. This
is necessary to prevent creation of deleted objects by another
thread, see http://archives.apache.org/eyebrowse/ReadMsg?listId=106&msgNo=1382";>this
for details.
Because the list archives are broken, I can't read that thread to see what
the problem was or the reasoning about the solution.
(3) PersistenceBrokerImpl.delete() calls objectCache.remove(), rather than
this.removeFromCache(). This has the effect described in (2), i.e., the
deleted object is removed from the cache but not from LoadedObjectsRegistry.
(4) After calling broker.delete(), StateOldDelete.commit() calls
broker.removeFromCache(). The latter call looks up the oid in the cache and
then removes the object it finds from LoadedObjectsRegistry. Because delete()
has already removed the object from the cache, LoadedObjectsRegistry.remove()
is called with null, and the object stays in the LOR forever.
As a result, it will never be possible to recreate the object in question.
I have fixed the problem by replacing
objectCache.remove(new Identity(obj, this, cld));
with
removeFromCache(new Identity(obj, this, cld));
in PersistenceBrokerImpl.delete(). But I think that this probably breaks the issue
mentioned in the LoadedObjectsRegistry comment. Perhaps somebody who understands
that issue could look into this bug?
An alternative fix, which seems somewhat less robust but won't trip over the issue
in (2), is for PersistenceBrokerImpl.removeFromCache() not to rely on the object
being in the cache in order to remove it from the LOR unless it has to. Here is a
patch implementing this solution:
public void removeFromCache(Object obj) throws PersistenceBrokerException
{
// objects must also be remove from LoadedObjectsRegistry
// Fix by Jamie Burns
Identity identity;
Object objectToRemove;
if (obj instanceof Identity)
{
identity = (Identity)obj;
objectToRemove = objectCache.lookup(identity);
}
else
{
identity = new Identity(obj, this);
objectToRemove = obj;
}
LoadedObjectsRegistry.remove(objectToRemove);
objectCache.remove(identity);
}
Can somebody please apply one or the other (or yet another, if that is appropriate)
patch to CVS?
thanks,
-steve

RE: New Functionality: Oracle-style JDBC Batching
Hi Can't wait for your new JCA connector. I'm using connection pooling in WebLogic. -Original Message- From: Matthew Baird [mailto:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 9:13 AM To: OJB Users List Subject: New Functionality: Oracle-style JDBC Batching For all our Oracle 9i users out there: Oracle has a special style of batching which is higher performance than normal JDBC batching. See http://technet.oracle.com/products/oracle9i/daily/jun07.html for more information. No special configurations are required, just make sure Batching is set to on in your connection information (repository_database.xml) ie. and use the new Oracle9i Platform setting in your build.properties ie. profile=oracle9i The implementation in the PlatformOracle9iImpl uses reflection to try and find the Oracle specific batching methods. It will degrade gracefully to use the default JDBC batching if the methods are not found. If your PreparedStatements are wrapped (ie you obtain connections from a JDBC pool in JBOSS) the Oracle batching will not work, as it won't find the methods. This will not be an issue after I check in the JCA connector, as you will use a raw connection and raw preparedstatements rather than from the app servers datasource (much easier to debug!). Just waiting for Thomas to tell me how/when to check that stuff in :) example results: PersistenceBroker API with Oracle style Batching [ojb] [performance] INFO: inserting 2500 Objects: 329 msec [ojb] [performance] INFO: updating 2500 Objects: 406 msec [ojb] [performance] INFO: deleting 2500 Objects: 391 msec [ojb] [performance] INFO: [ojb] [performance] INFO: inserting 2500 Objects: 344 msec [ojb] [performance] INFO: updating 2500 Objects: 406 msec [ojb] [performance] INFO: deleting 2500 Objects: 375 msec Raw JDBC with no batching [jdbc] [performance] INFO: inserting 2500 Objects: 1188 msec [jdbc] [performance] INFO: updating 2500 Objects: 1187 msec [jdbc] [performance] INFO: deleting 2500 Objects: 954 msec [jdbc] [performance] INFO: [jdbc] [performance] INFO: inserting 2500 Objects: 1203 msec [jdbc] [performance] INFO: updating 2500 Objects: 1171 msec [jdbc] [performance] INFO: deleting 2500 Objects: 954 msec OJB is no slouch ;) cheers, Matthew - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hopefully the sequence problems have been addressed by now? This is the last leg of a long journey to go into production with ojb and add another "success story" to the list.

Something wrong with PersistentLockMapImpl class
Hi! Does anyone use the PersistentLockMapImpl? I get a problem when I use PersistentLockMapImpl for lock map. I have two classes A and B. Their relation is non-decomposed association ,and their collection-descriptor be set proxy="true" each other. Like as: In my case, I use ODMG API to operate object persistence. At the same transaction , I first select a object of class A then select a object of class B and set a new value to B's currentState property. After the transaction finishing, the value of B's currentState did not be changed in database. I confirm it work if I set LockMapClass=org.apache.ojb.odmg.locking.InMemoryLockMapImpl in the OJB.properties file.Because our application has multi OJB instance at the same time, I must set LockMapClass=org.apache.ojb.odmg.locking.PersistentLockMapImpl. The lock properties are LockManagerClass=org.apache.ojb.odmg.locking.LockManagerDefaultImpl LockMapClass=org.apache.ojb.odmg.locking.PersistentLockMapImpl LockTimeout=6 ImplicitLocking=true LockAssociations=WRITE and ObjectCacheClass=org.apache.ojb.broker.cache.ObjectCacheEmptyImpl In my program , I new a Transaction.READ type transaction to query A and B. I try to query B first before query A, then set a new value to B's currentState property. The OJB ODMG can update field of B success even LockMapClass=org.apache.ojb.odmg.locking.PersistentLockMapImpl. Does anybody know why it is or tell me how to solve this problem?
New Functionality: Oracle-style JDBC Batching
For all our Oracle 9i users out there: Oracle has a special style of batching which is higher performance than normal JDBC batching. See http://technet.oracle.com/products/oracle9i/daily/jun07.html for more information. No special configurations are required, just make sure Batching is set to on in your connection information (repository_database.xml) ie. and use the new Oracle9i Platform setting in your build.properties ie. profile=oracle9i The implementation in the PlatformOracle9iImpl uses reflection to try and find the Oracle specific batching methods. It will degrade gracefully to use the default JDBC batching if the methods are not found. If your PreparedStatements are wrapped (ie you obtain connections from a JDBC pool in JBOSS) the Oracle batching will not work, as it won't find the methods. This will not be an issue after I check in the JCA connector, as you will use a raw connection and raw preparedstatements rather than from the app servers datasource (much easier to debug!). Just waiting for Thomas to tell me how/when to check that stuff in :) example results: PersistenceBroker API with Oracle style Batching [ojb] [performance] INFO: inserting 2500 Objects: 329 msec [ojb] [performance] INFO: updating 2500 Objects: 406 msec [ojb] [performance] INFO: deleting 2500 Objects: 391 msec [ojb] [performance] INFO: [ojb] [performance] INFO: inserting 2500 Objects: 344 msec [ojb] [performance] INFO: updating 2500 Objects: 406 msec [ojb] [performance] INFO: deleting 2500 Objects: 375 msec Raw JDBC with no batching [jdbc] [performance] INFO: inserting 2500 Objects: 1188 msec [jdbc] [performance] INFO: updating 2500 Objects: 1187 msec [jdbc] [performance] INFO: deleting 2500 Objects: 954 msec [jdbc] [performance] INFO: [jdbc] [performance] INFO: inserting 2500 Objects: 1203 msec [jdbc] [performance] INFO: updating 2500 Objects: 1171 msec [jdbc] [performance] INFO: deleting 2500 Objects: 954 msec OJB is no slouch ;) cheers, Matthew - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Still broken proxy m:n implementation
Hi!
I have downloaded rc4, and still not working.
My collection descriptor is:
the bean is working with
org.apache.ojb.broker.metadata.fieldaccess.PersistentFieldPropertyImpl.
The bean code for myList is like
public class MyBean implements MyInterface {
private List data;
public void setMyList( List newData ) { this.data = newData; }
public List getMyList( ) { return this.data; }
}
Just it.
If I delete an element from data (ex: getMyList().remove( 0 ) ), the real
object is deleted (even with auto-update and auto-delete = "false").
Any tips? I'm still doing something wrong?
Thanks,
Edson Richter

person2, then i add a new Test to person2.
this works when i set auto-update="true" in the reference-descriptor !
private void updateRef(PersistenceBroker broker)
{
Query query;
Criteria crit;
IPerson person1, person2;
ITest testObj = null;
crit = new Criteria();
crit.addEqualTo("id", new Integer(1));
query = new QueryByCriteria(Person.class, crit);
person1 = (IPerson) broker.getObjectByQuery(query);
testObj = person1.getTestObject();
crit = new Criteria();
crit.addEqualTo("id", new Integer(3));
query = new QueryByCriteria(Person.class, crit);
person2 = (IPerson) broker.getObjectByQuery(query);
// connect existing TestObj of person1
person2.setTestObject(testObj);
broker.store(person2);
broker.clearCache();
crit = new Criteria();
crit.addEqualTo("id", new Integer(3));
query = new QueryByCriteria(Person.class, crit);
person2 = (IPerson) broker.getObjectByQuery(query);
testObj = person2.getTestObject();
// connect to a new TestObj
Test testObj1 = new Test();
testObj1.setId(new Integer(77));
testObj1.setTest("New TestObj 77");
person2.setTestObject(testObj1);
broker.store(person2);

you can't null it

two choices:
1) Switch to primitives
2) do runtime checks. As in,

Switching to an int made it work, but now it's required. Is there a way

Hey guys,
I'm having a problem with a nullable foreign-key column not getting
updated.
I've got a table (Acknowledgements) that has a foreign key to the
Project table.
Now if I have all of the columns set for acknowledgements (including
projectID) all of the columns except projectID are getting set when I
call store(). The projectID is getting set to null.
If I comment out the reference call to Project from the Acknowledgement
table in my repository, the column gets set normally.
So the question is: Can I not just do an insert without a complete
object reference? I'm doing a lot of this over serialized XML so it's
not cool to have to pass an object graph just to do an isnert on a minor
related table.

Foreign Key column not getting updated
Hey guys, I'm having a problem with a nullable foreign-key column not getting updated. I've got a table (Acknowledgements) that has a foreign key to the Project table.

sub objects and a question on storing
Hey all, I am new to object relational bridges and I am trying to accomplish a fairly complex site. I have gotten pretty far I think looking through the demos and reading the a archives. Bows especially to Thomas for the helping hand he has given people for quite some time. Anyway, onto my two main questions. Question One: I am using PersistentNestedFieldMaxPerformanceImpl so that I can use "->" in the repository for nested objects. Are there plans to incorporate this in with other PersistentField Attribute implementations? Is the only difference between PersistentNestedFieldMaxPerformanceImpl and the default implementation that it accesses fields directly? Question Two: I have looked through the demos, but I am missing a piece of understanding about bridges. I have a simple reference-descriptor in my repository file as shown in the code below. I was trying to load a region based on a region id. I could not figure out how to auto-load a new RegionVO if regionId alone changed or was about to be inserted. This was "ok" as I knew I could manually load the new RegionVO object using a DAO. But here is the problem I was having: I would try to insert the LocationVO object before retrieving the RegionVO object. Instead of just inserting the populated regionId into the database, it would insert try to insert null and would null out the regionId during store().When I got the RegionVO first manually and populated it, regionId would be stored correctly. Why did I have to get the RegionVO first? The debug message I got about the field is just below: "[org.apache.ojb.broker.core.PersistenceBrokerImpl] INFO: Cascade store for this reference (RegionVO) was set to false."

In setter method I'm sending as a parameter Vector of new objects of type
UsersRoles - so If you want to clear all existing UsersRoles - you can't
based on new Vector. The only way I see it - to return a Vector of existing
UserRoles based on UserID - and delete these objects. Then - insert new
ones. But I'll better do it in DAO class, not in VO's setter. What do you
think?
I'm really wondering if (or why) it isn't done automatically by OJB? It's so
common situation. I think this routine must be accomplished by OJB.

Too stupid... :) or: a Bug in SqlGeneratorDefaultImpl?
Hello, after "hours" of debugging I found the problem with my m:n- mapping: the cause of it was that I used the same name for the collection- name and the (mysql- ) table very annoying, I should name all tables like "table_friends" now! :/ But perhabs the SQL- code which is generated by SqlGeneratorDefaultImpl could be made more robust? It would be nice to know that I'm the only one who had to find the sollution for this problem :) Here is the crazy but "faulty" code: SELECT A0.password,A0.nickname,A0.gbId,A0.imageFileName, (...) FROM USERS A0,friends INNER JOIN friends A1 ON A0.userId=A1.theUserId INNER JOIN USERS A2 ON A1.friendId=A2.userId WHERE (A1.theUserId = 163 ) AND friendId = A0.userId And it should be: SELECT A0.password,A0.nickname,A0.gbId,A0.imageFileName, (...) FROM USERS A0,friends A1 WHERE (A1.theUserId = 163 ) AND A1.friendId = A0.userId Thank you though for all your good work!, Hinnerk - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Getting the correct class instantiated
We would like to have a table that represents 3 or 4 different classes that share a common base class. When objects are created out of the table, one column in the table indicates which concrete class should be instantiated. These objects are refered to by a handful of different classes. I thought this was a perfect job for a RowReader, but the RowReader example seems to be a case of instantiating two objects out of one row, and our attempts at variations have not met with success. What is the correct approach to this? David This message contains information from Equifax Inc. which may be confidential and privileged.

Delete problem with QueryByCriteria
Hi I'm new in using OJB and so far I just try to follow the examples in
tutorials.
I'm using OJB 1.0.rc3 and MySQL DB.
In my code which is copied and modified a little from tutorial1.html
section - Deleting Object I noticed the following problem.
When I use
Query query = new QueryByCriteria(example);
to create query which will return the object that I want to delete
nothing happens.
But if I use
Query query = new QueryByIdentity(example);
The record is found and successfully deleted.
In the example in tutorial1.html QueryByCriteria is used.
Can someone explain what I do wrong? And is there a way to see what SQL
statement is generated in both cases?
Here is the complete code I'm using:
public void deleteUser(int userID) {
PersistenceBroker broker = null;
UserData example = new UserData();
example.setUserID(userID);
// 2. build a QueryByCriteria from this sample instance:
Query query = new QueryByCriteria(example);
try
{
broker =
PersistenceBrokerFactory.defaultPersistenceBroker();
// start broker transaction
broker.beginTransaction();
// lookup the product specified by the QBE
UserData toBeDeleted = (UserData)
broker.getObjectByQuery(query);
// now ask broker to delete the object
broker.delete(toBeDeleted);
// commit transaction
broker.commitTransaction();
}
catch (Throwable t)
{
// rollback in case of errors
broker.abortTransaction();
t.printStackTrace();
}
}

[jBoss] multiuser problems
Hi all, I have a j2ee client app that talks to the database via jboss and ojb. This app works fine when there is only one client talking to jboss at a time. It even works fine when I create several pseudo-clients in the same app running separate connections in their own threads (similar to the ojb ejb stress tests). However when I run this test with two separate client machines, each writing to completely different sets of objects, things silently hang in jBoss, and I cannot make any further remote calls. Note that there should not be a problem of simultaneous access to the same persistent object. I need to restart jBoss to be up again. I realize that I am only giving a general description of the problem, and I intend to investigate further so that I have (hopefully) some stack traces instead of silent death. But first a few pointers to help me in my investigation would be very welcome. First my setup is the following: WinNT - jBoss 3.0.6 - ojb1.0rc2 - Oracle 8.1.6 I've held off moving up to rc3/4 due to the myriad of sequence problems that I and numerous other Oracle users experienced with rc3. I'm willing to roll up my sleeves and move to rc4 if required (is it possible that this is a bug that has been address recently -- I don't see any bug reports quite like this). Hopefully the sequence problems have been addressed by now? This is the last leg of a long journey to go into production with ojb and add another "success story" to the list.

I would try to do all the modifications to the userUR - Collection that
is given to you by the system because it is a 'RemovalAwareCollection'.
this would be my setUserUR method:
public void setUserUR(Vector userUR) {
this.userUR.clear();
this.userUR.addAll(userUR);
}
and then persist the whole thing.

Newby deployment question, placement of common libraries (struts, ojb) ?
Hi, we have a J2EE application which uses ejb's, ojb and struts. OJB and Jakarta-Struts depend (among others) on some common libraries, i.e. commons-beanutil.jar. Which of the the two following solutions do you recommend ? 1. The common (=common to both, ojb and struts) libraries are placed in the ear only once. 2. The libraries are placed in the ear file two times, once in the WEB-INF/lib of the webapp, and once in the root directory of the archive. Is there a possibility that ojb and struts will depend on two different versions of the commons-libraries ?

Re: Problem of dynamic proxy?
MessageHi! Jim
I have solve this problem.There is not any way to repleace Dynamic Proxy.
But I can tell you how to use "Proxy" via OJB correctly.
1. The class A there is a referance to class B , and the class-descriptor of A must be
declared a reference-descriptor for B.
code
--
public class A{
:
:
private String bOID;
public String getBOID(){...}
public void setBOID(String pNewValue){...}
private InterfaceB objectB;
public InterfaceB getObjectB(){...}
public void setObjectB(InterfaceB pNewValue){...}
}
public class B implement InterfaceB{
public int get**(){...}
:
:
}
public interface InterfaceB {
public int get**();
:
:
}
repository-user content
--
:
:
:
:
:
:
2. The class A there is a collection property that elements of collection are B, and
you want to lazy load elements of collection when OJB load A.
code
--
public class A{
private String OID;
public String getOID(){...}
public void setOID(String pNewValue){...}
:
:
private Collection manyB;
public Collection getManyB(){...}
public void setManyB(Collection pNewValue){...}
}
public class B{
private String aOID;
public String getAOID(){...}
public void setAOID(String pNewValue){...}
}
repository-user content
--
:
:
:
:
:
:
:
:
In case 1. You must add a interface class for B and in respository file declare
class-descriptor for it. Then change the setting of class A and B in respository file.
Set the B's proxy attribute is important.
In case2. If you want to set collection propertise in your programs lazy load (like
us), just declare the proxy attribute of
collction-descroptor true.
If you still have problem about lazy load(proxy), mail to me.
