• download jdk-6u45-linux-i586.bin and jdk-6u45-linux-x64.bin fromhttp://www.oracle.com/technetwork/java/javase/downloads/index.html (yes, both, no matter which version you will run)
• download jce_policy-6.zip from the same page under "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 6"
• on multiarch amd64 systems (Wheezy) one must add i386 architecture: dpkg --add-architecture i386 && apt-get update
