Alfresco open sources JLAN, a Java-based embedded virtual file system Alfresco just open sourced its intelligent file drive system.

I've put the jar files in a new folder, added that folder to the PATH and CLASSPATH, and added that to the build path as an external library.

Newer versions of Java now require all JAR files to be signed with a valid code-signing key, and starting with Java 7 Update 51, unsigned or self-signed applications are blocked from running.
