error on query.create("...

[Fabiano Fernandes de Souza]

I am getting a NullPointerException when the execution reaches the line:

query.create("select users from users in "+FlUserBO.class.getName()+"
where users.identification = $1");

in the code above. Some one can tell me what's wrong?

Thanks.

 Implementation impl = OJB.getInstance();
Database db = impl.newDatabase();
db.open("default", Database.OPEN_READ_WRITE);
try{
Transaction tx = impl.newTransaction();
tx.begin();

OQLQuery query = impl.newOQLQuery();
query.create("select users from users in
"+FlUserBO.class.getName()+" where users.identification = $1");
//query.bind(_identification);
//DList results = (DList) query.execute();
//FlUserBO user = (FlUserBO)results.iterator().next();
tx.commit();
db.close();
return  null; //user;

Persisting Date and Time

[Fabiano Fernandes de Souza]

I got in a value object a property named recDate of java.util.Date.

It's mapped in resource.xml as jdbc-type="DATE" and 
mapped in the ddl as rec_date TIMESTAMP.

I persist the object with the current Date using something like:
"setRecDate(new Date()) and then I persist it using ODMG.

Everything goes fine but in the table keeps registered only the date
(not date and time) like this: 2004-01-06 00:00:00

What can I do to register the date and the time too?

Thanks.

Getting the Id in insertion time.

[Fabiano Fernandes de Souza]

I'm using auto-increment fields. 
The OJB defines the new ID for this fields when I insert a new record.
I would like to know how can I know those new ID's values after the
insert task using ODMG.

There's a function that record the object in the database and return the
ID value?

Otherwise, what can I do?

Ojb samples

[Fabiano Fernandes de Souza]

Please,

Can anyone send to me some resource.xml source code fragment where is
declared the jdbc-connection-descriptor for a postgresql jdbc?

I am a newbie and my bigest problems is to start to use it on my Web
application. I couldnt find any samples how to use it on Web
Applications. Some codes of config files and servlets using the ojb
framework for inserts or queries would be fine.

Thanks.
