Hi,

I can't reproduce the problem. Everything works for me. I guess you
have an old Jackrabbit jar file somewhere in your classpath. My test
case:

import javax.jcr.*;
import org.apache.jackrabbit.core.TransientRepository;
public class Test {
    public static void main(String... args) throws Exception {
        System.setProperty("log4j.configuration", "file:log4j.xml");
        Repository repository = new TransientRepository();
        Session session = repository.login(new SimpleCredentials("",
"".toCharArray()));
        Node root = session.getRootNode();
        Node n = root.hasNode("test") ? root.getNode("test") :
root.addNode("test");
        n.setProperty("test", "abc");
        session.save();
        session.logout();
    }
}

Jar files:

commons-collections-3.1.jar
commons-io-1.4.jar
concurrent-1.3.4.jar
h2-1.2.121.jar
jackrabbit-api-1.6.0.jar
jackrabbit-core-1.6.0.jar
jackrabbit-jcr-commons-1.6.0.jar
jackrabbit-spi-1.6.0.jar
jackrabbit-spi-commons-1.6.0.jar
jackrabbit-text-extractors-1.6.0.jar
jcr-1.0.jar
log4j-1.2.14.jar
lucene-core-2.4.1.jar
slf4j-api-1.5.3.jar
slf4j-log4j12-1.5.3.jar

repository.xml: the same as your, except i replaced

<!--	<LoginModule
class="com.inubit.ibis.server.repository.IBISLoginModule"/> -->

with

        <LoginModule
class="org.apache.jackrabbit.core.security.simple.SimpleLoginModule">
           <param name="anonymousId" value="anonymous"/>
           <param name="adminId" value="admin"/>
        </LoginModule>
