First, you can always invoke ant with the -v option for more information
(or even -debug for usually way too much information).
Second, I see in the source of the verify task that the classpath option
of the task is called 'verifyClassPath' whereas you have 'verifyclasspath'
(note the lowercase).

Hi Andre,
I guess the problem is: the collection returned by getCollectionByQuery()
contains dynamic proxies, not MGT_Requests. So you should cast to an
interface that MGT_Request should implement if you want to use dynamic
proxies (does it?), see
Hi Jay,
for IDE debugging with WSAD I'm not using a Datasource but a JDBC connection because
in the case of the datasource you have to set up the datasource for each developer box
manually

Hi Thomas,
thanks for your answer. I checked again, but still I get a
NoClassDefFoundError. Unfortuanately there is not stacktrace so it is
quite difficult to find it.
The class kos.generator.DataObject is located in the ojb-generator.jar
file. This jar is correct because I am using this JAR

Thanks very much for your help.
I better understand now.
In fact I did'nt want particulary use dynmic proxy. I put it because I
look at some examples to create my repository file (I am quite lasy!)
Effectively, with my workaround it works good. I will look at the

hi dogie,
i can't see the difference between the two mappings except the sequence of the
definition of the IA-classes :(
do you have an sql trace to show the different behaviour ?

Another question :
I just start to use autoincrement with sequence manager. It works good.
Is it any way to get directly the value affected by the sequence manager ?
Not sure what exactly are you asking for. Can you please rephrase your question?
Hi All,
We're using a hsqldb database for part of our application, and need to
package the database files up into a zip archive before exiting. Problem
is, OJB doesn't seem to be closing the database connection so the files
are still locked and we can't delete them once they are in the Zip file.
Not closing the connection is kind of the whole point of connection pooling, and OJB
provides connection pooling. Database connections are typically expensive to
establish, so rather than each time you use the database creating a new connection and
then releasing it at the end connections are
I've changed the verify ant task so that it now accepts a classpath
sub-tag instead of the verifyClassPath attribute. Check the build.xml in
CVS to see how its used.

Hi Lance,
Pools are great and I don't really want to get rid of that by using
ConnectionFactoryNotPooledImpl. However, I found part of the answer.
Each of the ConnectionFactory's has a releaseAllResources method which
will close all the connections in the pool (exactly what I want).
Anyway,

In the previous versions of OJB it wasnt necessary to create

Is creating the reference object
the right thing to do or is there some way to
