I'm afraid not. I dropped in the newer version of Lucene, and that
fixed the problem for me, but I'm not doing anything in particular
with OSGi.
If it matters, I'm using Guice for dependency injection, and using
Blueprint to wrap around Neo4J:
import com.google.inject.AbstractModule;
import com.teachscape.commons.settings.Settings;
import com.teachscape.commons.util.Files;
import com.tinkerpop.blueprints.pgm.Graph;
import com.tinkerpop.blueprints.pgm.TransactionalGraph;
import com.tinkerpop.blueprints.pgm.impls.neo4j.Neo4jGraph;
import java.io.File;
public class Neo4JModule extends AbstractModule {
private final Settings settings;
public Neo4JModule(Settings settings) {
this.settings = settings;
}
@Override
protected void configure() {
String graphdir = settings.getSetting("neo4jdb.dir");
File f = new File(graphdir);
if (!f.isDirectory()) {
f.mkdirs();
}
boolean startClean =
settings.getBooleanSetting("graphdb.startClean", true);
if (startClean) {
Files.delete(f); // Neo4jGraph will mark as 'fresh' when
it detects dir doesn't exist
if (f.exists()) {
throw new IllegalArgumentException(
String.format("graphdb.startClean=true, but
can't delete directory %s", f.getAbsolutePath()));
}
}
Neo4jGraph graph = new Neo4jGraph(graphdir);
graph.setTransactionMode(TransactionalGraph.Mode.MANUAL);
bind(Graph.class).toInstance(graph);
bind(Neo4jGraph.class).toInstance(graph);
bind(GraphShutdownHookInit.class).asEagerSingleton();
}
}
Blueprints 0.7, Neo4J 1.4-SNAPSHOT, Lucene 3.2.0.
In my test code, Index<Vertex> index = ((IndexableGraph)
graph).getIndex(Index.VERTICES, Vertex.class); then works, whereas at
first it didn't because of problem with the older Lucene.
Cheers,
Eelco
