Hi Mirko,
Thanks, I have not been able to reproduce, and we are looking into
this now ...

Yep, you need to include some more libraries in your classpath.
Elmo1.4 depends on the following (required) libraries, included in
the Elmo download:
dist/elmo-1.4.jar
dist/elmo-rdfs-1.4.jar
lib/persistence-api-1.0.jar
lib/commons-beanutils 1.7.0
lib/javassist-3.7.ga.jar

Any ideas as to how to resolve this, seeing as it runs on your

Hi Hugh,
1) I checked VirtuosoTest.java again. Test 1 passes only if the
graph "http://demo.openlinksw.com/demo#this"; is already in the
DB. I oversaw this in my last run. Is this maybe intended? Test 4
passes in the first run, but fails when re-running the tests (the
tupleQuery in test 4 returns 1 result, but the utf8 string
doesn't equal the original). After restarting Virtuoso, test 4
passes again.
2) Attached you find my test programm that throws the
AbtractMethodError. You need Elmo1.4 in your build path to run
it. Data in Virtuoso are not required. Can you reproduce the
exception in your environment?
Thanks, Mirko

Hi Mirko,
Can you please provide the output of running the following
command on you Mac OS X client:
java virtuoso.jdbc3.Driver
Please also provide the complete screen output of running the
Sesame tests program on your machine ...

Hi Hugh,
sorry I didn't test that in advance... No, I can't run all
tests successfully. Tests 1,3,4,8 fail. Nothing is written to
virtuoso in the failing tests, so no exceptions but 0 results
from the tupleQuery.
btw: when re-running the tests, test 1 passes. I figured out
that test 1 passes when running something like the following
before (which is done in test 4):
URI testuri = repository.getValueFactory().createURI("http://
foo.bar/test");
URI name = repository.getValueFactory().createURI("http://
foo.bar/name");
Literal value = repository.getValueFactory().createLiteral
("abc");
con.add(testuri, name, value, context);
Here is my environment:
#virtuoso:
- Version: 05.10.3037, Build: Feb 18 2009
- running on ubuntu.
#client-side:
- Mac OSX 10.5.6
- Java 1.6 (same results with java 1.5)
build path:
- openrdf-sesame-2.2.4-onejar.jar (same results with sesame-2.1.2)
- virt_sesame2.jar
- virtjdbc3.jar
- slf4j-api-1.5.6.jar
- slf4j-jdk14-1.5.6.jar
- slf4j-log4j12-1.5.6.jar
Can you give me some info what could be wrong with my setup?
Thanks, Mirko

Hi Mirko,
Have you been able to successfully run the Sesame2 sample
test program we provide as detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/
VirtSesame2Provider#%20Setup
If so can you provide a sample program we can run to test your
issue in-house ?

Hi,
I get an "AbstractMethodError" exception when retrieving data

Virtuoso using the Virtuoso Sesame2 driver in connection with
Sesame2.2.4 (and Elmo1.4). Here's some simple test code that

the exception:
Repository repository = new VirtuosoRepository("jdbc:virtuoso://

ElmoModule module = new ElmoModule();
SesameManagerFactory factory = new SesameManagerFactory(module,

The above code works fine with other repositories (such as
NativeStore, MySQL, MemoryStore). Is this a bug in the
Virtuoso Sesame
driver?
Thanks for any comments! Mirko
