After the last import Thawte generated certificate problem (Failed to establish chain from reply), I now seemed to have gone pass that and moved onto the next problem: I imported Thawte's public certificate and Thawte generated certificate into IE6 and then export the generated certificate in.p7b format. I then tried to import this .p7b format into my keystore and I have this error: keytool error: java.lang.Exception: Certificate chain in reply does not verify: Signature does not match. Any ideas please?! Thanks in advance!
