In order to run tiddlywiki on Opera you need 2 files the empty.html and the jar file:

But you also need to have java installed (see Enabling Java in Opera for Linux - Opera Knowledge Base)

sudo find / -name libjava.so /usr/lib/jvm/java-1.5.0-sun-1.5.0.17/jre/lib/i386/libjava.so

if it's not there

sudo apt-get install sun-java5-jre (1.5.0-17-0.1)

and then you need to go into Opera / Tools / Advanced / Content and tick "Enable Java"



go into "Java option" and put the Java's path

Then you need to quit + relaunch Opera, and load your local tiddlywiki
