Thanks, that is more clear. In earlier versions of ultrasearch/intermedia, one was told to do strange things with the java objects as regards reinstallations or upgrades, I don't even want to _look_ at that stuff anymore - I always suspected some of the notes relevant to that were wrong, they were certainly confusing. OAS10g seems to have finally worked that out, but I just get antsy thinking I'll have to go through another 9iAS patching hell sometime.
