Hello Jena-rous people, Thanks for your help, it looks like I have a running config. @Nikolaos Abatzis Thanks for drawing my attention to the change com.hp... -> org.apache... @Paolo Castagna You wrote > Have you tried to upgrade from 3.0.3 to 3.1.x? > Did you experience problems? No change was needed in LARQ to work with Lucene 3.1. Here's what I did: * grabbed the larq sources from https://jena.svn.sourceforge.net/svnroot/jena/LARQ/tags/larq-0.2.0 into a project of mine * changed imports from com.hp.*.larq to org.apache.*.larq, * compiled with lucene-core-3.1.0 & arq-2.8.7 * The remainder of my sources don't import anything larq-ish, I compile them with - said project of mine - tdb-0.8.9 minus Lucene jars, - lucene-core 3.1.0, - lucene-analyzers 3.1.0. All together, they load & run OK. > Jena code has not been migrated to the Apache infrastructure yet > and there are external (to us) dependencies for this. > But, I would imagine we are very close to it, now. The not-so-snug part is to have to rely on LARQ in source form; I'm looking forward to seeing the maneuver completed. > ARQ will not depend on LARQ (to avoid cyclic dependencies), but use it > dynamically when present in the classpath. > Does this seem reasonable to you? If some parts of ARQ use LARQ nowadays, I'd say my apps don't load those parts. I rely on hearsay about this, because it's a bit messy to remove the com.hp.*.larq classes from the classpath right now. Notice that my use of LARQ is confined to 2 classes: I subclass IndexBuilderNode & IndexBuilderSubject. More on this in a coming mail. Thanks again for your help. Cheers, François Jurain.
