I did not close Eclipse IDE it was running until now, and just now I closed it to check whether it is the case, but still I am getting that error message. - or it finished some other way > before you tried deleting (or you shouldn't have been able to delete > the derby.jar). I experienced this several time after this error occurred, that is sometimes I forgot to exit ij before trying to delete jars, which gave me an error. I did a bit investigation on this, by deleting jars one by one as in order they give me that particular error. But not sure whether it will useful to give me an exact reason/ possible reasons. Jars needed to delete: derby.jar derbytools.jar derbynet.jar derbyclient.jar derbyrun.jar Thanks, -- Best Regards, Nirmal C.S.Nirmal J.
