I've created mindmap in freeplane and then export it as "Java", that gave me a html file and a folder.
When I open this html file in windows it works correctly in Google Chrome and Firefox. But opening it in ubuntu, it's not working.
In Firefox, FF asked me to allow IcedTea plugin but even I allow it, it always cause my computer to crashed
In Chrome, it always redirects me to java download page
What should I do?
I saw some advice about running applet in "appletviewer" but I don't know how to install "appletviewer", either
