Re: Exception in thread "main" java.lang.ExceptionInInitializerError
I am pretty sure that the full repository files are included in the ojb-blank jar -- I just tested it anyway and they are. they should all be located in ojb-blank/src/resources/ -Brian On Feb 14, 2004, at 10:37 AM, Sven Alisch wrote: Hello Armin, The Template i use, ojb-blank, only includes a repository_user.xml file.

Re: OK Last Question for Today!
If all declared xml-reference files are in the same directory as the repository.xml file, OJB will start reading metadata. If something wrong with your metadata definitions, please enable debug logging level for org.apache.ojb.broker.metadata.RepositoryXmlHandler org.apache.ojb.broker.metadata.ConnectionDescriptorXmlHandler in properties file of your log-api. If you use OJB default, you can set this in OJB.properties file.

Re: [BOOT] ERROR: Creation of PersistenceBrokerFactory (PBF) instance failed, can't get PBF class object
hmm strange, your posted error message says that property
'PersistenceBrokerFactoryClass' could not be found, so maybe your
OJB.properties file is corrupt or OJB read the "wrong" file.
Try something like
-DOJB.properties=../ressourcec/OJB.properties
regards,
Armin

Re: [BOOT] ERROR: Creation of PersistenceBrokerFactory (PBF) instance failed, can't get PBF class object
Thanks Armin,
for the fast answer! First I edited the build.xml file for setting references
to that file, later i copied it into the lid dir and now I copied that file
in my classpath /usr/lib/java2/jre/ext ..., but the result is always the
same. I get this error message.
greetings,
sven

I create my application from template ojb-blank.
I created my repository_user.xml in directory ./src/ressources/ and it looks

My Class for that exsample is:

Re: QueryFactory issue
Hi,
sorry I got it. It is a database-error. Access doesn't return memo
fields when using distinct (g). my fault.

Re: Cache issue
Hi Tino,
I don't think that OJB is the problem (but maybe I'm wrong). The only
difference between the Criteria is the 'distinct' flag. So I this Access
has a problem with the distinct flag. Please enable p6spy to trace the
generated SQL statements.
See
http://db.apache.org/ojb/faq.html#How can I trace and/or profile SQL
statements executed by OJB?
How does the generated SQL for both Criteria look like?
Try to invoke these statements against your DB and compare the results.
If both statements return the same result ... OJB has a problem ;-)

Armin

configuration problem:
I have a class Person which has one LONGVARCHAR-Field. The first time
the object is accessed the LONGVARCHAR-field is returned correctly.
hmm, does this mean first time after creation? Which cache was used?
Maybe first time after store it was found in cache, second time it was
read from DB. So I assume your "database" truncate the String on insert.
Maybe I'm wrong ;-)
regards,
Armin
But the second time it is accessed it returns just 256 (I suppose)
characters.
I am using Access as 'database' but I don't think this is the problem.
Do you have any ideas what I could try?

RE: Unique column
Here's my recommendation: 1) Implement the PersistenceBrokerAware interface in your persistable object (ie. Employee). 2) In the beforeInsert callback, check the database for a record with an employee name that matches the employee name of "this". 3) In the beforeUpdate callback, check the database for a record with an employee name that matches the employee name of "this" and where the id of the existing record doesn't match the primary key of "this". For steps 2) and 3), you can use the PersistenceBroker that's passed in via the specified callback. For details, check out the javadocs related to the PersistenceBrokerAware interface.

Don't forget to set this in database too (all good databases around the world support primary keys). Other way: in OJB uses it as normal field, and in database create a UNIQUE index.
