Am I the only one who experiences this problem
or thinks that it is indeed a problem?

Is there any known problem when using
Sesame/OWLIM-Lite on a 32 bit Linux system with
JDK 1.7.0_02?
I am seeing a hanging condition which does not occur
with Java 1.6.x in my app which embeds OWLIM-Lite
and thought I ask about this before digging deeper.
Cheers,

As was pointed out to me, Sesame 2.6.3 seems to fix problems
with using Java 1.7. So I am wondering is Sesame 2.6.3
officially supported and known to be compatible with
OWLIM 4.3 (especially OWLIM-Lite 4.3.4248 which originally
came with sesame 2.6.0)?
Should I assume compatibility if Sesame is rec
Hi, from my experience there is problem with jdk1.7.x and Sesame. In my case I
can't simply run Sesame Console, so I think the issue is connected somehow with
sesame. Try to replace your version of sesame lib, with the new one 2.6.3(it is
not mentioned on main page but it is in download reposito
Hi Barry,
I am just raising this issue again.
Sometimes the com.ontotext.AVLRepositoryManager bean does not seem to
register itself other times it does.
I get the instance via the PlatformMBeanServer which works most of the
time but sometimes there is nothing there.

Hi Jerven,
I also wasn't able to reproduce your problem, nor do I see anything wrong with
the code registering the mbeans. Could you please have a look at the Sesame
logs for any warnings about failing to register mbeans?

Johann, we experience this problem also with OWLIM-Lite.
Barry Norton at a Meetup in NYC recommended going to
OWLIM-SE, if you can get a copy from Ontotext.
We have our copy but have not tested it yet.

Hi Dimitar,
No nothing shows up in the logs. Anything I should look out for?
By the way I do not use the sesame web app so if the mbean registering depends
on this somehow let me know.

Hi Johann,
We have a test-case to check for excessive execution times that uses
OWLIM-Lite with the owl2-rl-conf ruleset and a handful of statements. I
tried adding a lot more statements and it does take longer, but nowhere
near as long as you say.
The only way I can make things take an exce
Hi Barry,
this occurs in the GATE ontology plugin which uses
OWLIM-Lite as the backend. Moving to OWLIM-SE is
therefore not an option :)
The Ontology plugin traditionally uses by default
the owl-max ruleset with the partialRDFS option set
to "false" (this was determined a longer while ago
to prov
Hi Jerven,
No, you don't need the webapp. I meant warnings like "Error registering so-
and-so mbean".
How exactly are you initialising and using owlim?

Hi Dimitar,
I use a spring config that creates a "ConfigRepository" object which
extends OwlimSchemaRepository. This is a thin wrapper to inject
properties into the owlim code without using the system properties.
So basically by calling the OwlimSchemaRepository constructor.

Jerven
Hi Jerven, Dimitar,
This might be stating the obvious, but when OWLIM is deployed with
Tomcat (and the Sesame webapp) then it won't register anything until it
is loaded for the first time.
(During an OWLIM-Enterprise install, users have to click on something in
the workbench, e.g. 'query', w
Hi Johann,
We do not generally test with Java 1.7 and hence do not officially
support it. However, if you are having trouble then we would very much
like to hear about it.
Best,

Hi Barry,
Well lets put it this way after inserting a few million statements into the an
OWLIM repository the beans is not visible. Nor is it after a few queries
against the repository.
Does it depend on a specific class being loaded? I am looking for the

Hi Jerven,
Everything seems fine. Can you reproduce the problem reliably - i.e. are the
MBeans missing always for a given configuration or only sometimes? They should
be present after OwlimSchemaRepository.initialize() completes.
Also, I'm not familiar with Spring and this might sound stupid, b
Hi Barry,
I think that in the code path that I use the following method may not be called.
public class com.ontotext.trree.big.AVLRepositoryMBeanFactory
public java.util.List createAndRegisterMBeansFor(com.ontotext.trree.big.h)
i.e. is there a guarantee that this method is called when constr
Hi Jerven,
If this method isn't called, this points to a problem with your classpath
configuration. There should be a file called
META-INF/services/com.ontotext.trree.mbeans.MBeanFactory
on your classpath - most likely in the owlim jar.

Hi Ditmar,
They are sometimes available although today I have not seen them :(.
OwlimSchemaRepository.initialize() completes succesfully
Spring in my config adds two beans to the platform mbean server but when
removing it the Owlim mbeans do not appear.

Thank you for that information!
As I already mentioned elsewhere, the problem appears when using
OWLIM-Lite with Sesame 2.6.1 but went away with Sesame 2.6.3
so this seems to be a Sesame problem really.
Therefore I would also be interested in what the official statement

Hi,
I don't know if this is relevant or not, but doing some tests with OWLIM-Lite,
and sometimes having to delete one context in the repository, I noticed that
using the Sesame work-bench's "clear" option on a context was much slower then
