Hi,
I have a class file with an 'long id' autoincrementally. During
byte-code enhancement, I get the following error :
[java] Error while enhancing: JDO ENHANCER: At least one error
occurred while enhancing input class for Transparent Persistence;
detailed message(s): nested exception:
It should be ok.
The reset name seems fine to me.
Thanks,
Guillaume

thx for your answer Guiiaume. I already did this and use the example (basic)
cache.ccf file from the jcs homepage. But I am using JCS the first time and
there is no much docu available, so I am wondering how it all works. Is it
as easy as
broker.beginTransaction();
broker.insert(persistObject);
Hi Dirk,
you don't need to cache the objects by yourself it will be done by OJB.
If you want to manipulate the cache use the service method provided by PB:
PB.serviceObjectCache()
or to remove objects from the cache, yu can find methods at PB.
broker.beginTransaction();
You should not bother accessing direcly jcs.
The cache will be created by ojb and
you can retrieve objects using ojb
with a broker.getObjectByIdentity.
For the jcs cache implementation in the ojb distrib,
you're right that it should use a string as the key.
Personnally, i copied the given class
Hi Armin,
oh I see, great. This simplifies it for me. I have two more questions: If I
do not specify an expiration time of the cached object in cache.ccf, is
there a default 'remove objects from cache implementation which will be
invoked after a certain time? What about the memory shrinker
Hi Alexandre,
could you send the java class ?

Hi Nicolas,
I use the enhancer provided by jdori (com.sun.jdori.enhancer) and

I don't know, because I have a similar class without problem during

Here my class file :

Hello,
we have a strange siuation where collections are *NOT* updated in the object cache

A.getBs() - auto-delete=true

You should ask to the mailing list of jcs for such questions.

Just to now. Be careful if you want to use the OJB plugging for JDORI
because it doesn't work very well (or I don't now how to use it).
The 1..n and n..m relation have problem with the persistence by
reachability. When you get object with a query, reachable
Ok, I continue to search any solutions.
Which tool you use to enhance byte-code ? (other that JDORI).
I have a case of update that running good with 1..n relation. But I
didn't look further these tests.
Thanks,

Nilesh, if you are still having difficulty, it is time to step through the
code with a debugger, like Eclipse. But first, you'll need to get the OJB

This because rc5 and rc6 are not

We use Jasper Reports and iReport extensively. Jasper Reports generates
reports based on an XML definition. The data source could be JDBC or a

records using OJB and pass the collection to Jasper Reports for
