Jortho (java orthography) is a spell-checker entirely written in java. its dictionaries are based on the free wiktionary project and can therefore be updated for virtually any language.

the library works with any jtextcomponent from the swing frame work. this includes jtextpane, jeditorpane and jtextarea.

the version packaged is based on jortho 0.4, slightly adapted for the needs of freeplane. see http://jortho.sourceforge.net/.
