Hello Armin,
no, I have allready replaced all CGLib classes width JDK classes. My
problem is, that i can't debug the following issue: -------- Caused
by: java.lang.NullPointerException at
org.apache.ojb.broker.core.QueryReferenceBroker.access$000(QueryReferenceBroker.java:64)
I think this is the access from the inner class
PBMaterializationListener to the private field 'pb' in class
QueryReferenceBroker.
Decompiled code for QueryReferenceBroker:
...
static org.apache.ojb.broker.core.PersistenceBrokerImpl
access$000(org.apache.ojb.broker.core.QueryReferenceBroker);
Code:
0: aload_0
1: getfield #4; //Field
pb:Lorg/apache/ojb/broker/core/PersistenceBrokerImpl;
4: areturn
at
org.apache.ojb.broker.core.QueryReferenceBroker$PBMaterializationListener.addThisListenerTo(QueryReferenceBroker.java:990)
-------- <code> Line 990: _listenedHandler =
pb.getProxyFactory().getIndirectionHandler(owner); </code>
pb is != null
I have no idea :o/. Are there any no features, that I have to keep in
mind?
I remember that I got a similar ".access$000" error some weeks ago. But
I can't remember the reason. I thought it was a proxy issue (do you get
the same error when using CGLIB-proxy classes?) - but seems this isn't
the reason.
Could you describe or post the test source code to reproduce the issue?
regards,
Armin

Hi Josef,
could this be a proxy issue? Please check the settings in
OJB.properties file - do you need CGLib based proxies?

Hello List,
I have a problem width loading large data from tables width
clob-culumns. db: oracle 9.2.0.8 ojb: 1.0.4 driver: thin
When i load 15000 rows, my applikation gets an
OutOfMemoryError. I have ensure, that Oracle width clobs is
the problem, width HSQLDB, all works fine. The data in the
clob-culumns are texts width AKTUALLY no more then 100
charakters.
I have checked out the trunk of ojb and I see, that in the
platform package are some wrapper-classes for clob und blob?
yep, I reworked the LOB-support a bit and add Blob/Clob
java-types support (before OJB converts all LOB's to byte[]).
Unforunatelly, I can't test if this is the solution of my
problem, because I get lots of errors when starting my
application width a jar from the trunk version.
Don't use the trunk it's the alpha OJB 2.x. Please check out
the OJB_1_0_RELEASE branch it's the stable upcoming OJB 1.0.5
version.
Can anybody tell me, if the source in the trunk is the
solution for such problems I have?
Don't know - give it a try.
Or is the solution to switch to oralce 10g?
I run the LOB-test against OracleXE 10.2.0.1 and
classes12_g_10.2.0.2.jar driver.
http://svn.apache.org/viewvc/db/ojb/branches/OJB_1_0_RELEASE/src/test/org/apache/ojb/broker/lob/LOBTest.java?view=markup
The tests handle CLOB's up to 5000 characters.
Or should I use OCI instead of THIN driver?
Sorry I don't know (not a Oracle expert).
regards, Armin
Thanks a lot for your answers.
