Installing Java

Freenet is written using the Java programming language. To run it you need Java installed on your machine. You may already have it but if not we strongly recommend you download the version of Java made by Sun, which can be freely downloaded from Java.com∞.

Blackdown worked fine last time I tried it if Sun's jre isn't an option for some reason, even though it was the ancient 1.4.1, but it's a hassle to set up. It doesn't include needed cryptography providers, so you have to download GNU Crypto∞ and edit the policy files to use it. Also Freenet 0.7 *does* run on GIJ, but slowly; we haven't been able to identify why yet. For more Information see Freenet 0.7 with free VM
