It's integrated, i.e. it deploys on an OSGi container. And the Ignite part works. But at soon as it delegates to Spring to parse the context XML, the latter complains about namespace handlers not being found.
Spring DM looks into bundles to find NS handlers. So without Spring DM such problems are expected. Maybe it does work after all if we refrain from using certain namespace like util. I'll have to check that tomorrow. Raúl.
