Subject Re: setting encryptionKey attribute in jdbc url
Date Tue, 01 Dec 2009 08:41:21 GMT
Hi George,

key.getEncoded() returns a byte array that is a textual representation of
the external key in Hex.

Just Stringify the byte array and set it to the 'encryptedKey' JDBC
connection URL attribute - that should work.

Cheers,
