qualcuno mi suggerisce qualcosa?


ho provato ad installare anche  apt-get install libgcj, come suggeriva qualcuno ma non funziona.


grazie mille

Risolto:

ho installato tutti i pacchetti sun-java6.

dopo l'installazione ho scelto  /usr/lib/jvm/java-6-sun/jre/bin/java (sun_java) per l'esecuzione dei pacchetti

update-alternatives --config java
