Please follow the installation instructions for JCE1.2
(http://developer.javasoft.com/developer/earlyAccess/jdk12/jce12_install.html).

Under item 4, you will find the following instruction:

4.Install the SunJCE provider.

SunJCE is the built-in provider that comes with JCE 1.2. You can install
the SunJCE provider in two different ways:

Dynamic registration

Add the following lines of code at the beginning of your program:

import java.security.Provider;

Provider sunJCE = new com.sun.crypto.provider.SunJCE();
Security.addProvider(sunJCE);

Static registration

Add the following line to the security property file of your JDK
installation, where you configure your crypto
providers. Substitute n for the priority that you would like to
assign to the SunJCE provider:

security.provider.n=com.sun.crypto.provider.SunJCE

Thanks,

Jan
