What U have to do is sign the file containing the classes that will load your DB drivers.
e.g I'm using Oracle's DB, so those files are in a file named classes111.zip; all I had to do was sign that file and everything worked like a charm.In order to sign Ur jar files U will need to use the jarsigner tool shipped with JDK1.3 and up (previous versions don't support RSA...) and a certificate, issued either by a CA or self created by yourself.The jarsigner tool is really simple to use.%j2sdk%\bin\jarsigner filetosign.jar aliaswhere 'alias' is the name of the private key in the keystore U have created; there are quite a few other parameters you can add, and for further details take a look here:http://java.sun.com/products/jdk/1.2/docs/tooldocs/win32/jarsigner.html
