Prsentazione // Problema

[angmgio]

Ciao a tutti, sono l' ultimo arrivato

Scrivo questo post per salutarvi e chiedere aiuto.

Ho cercato di seguire il tutorial Java, ma purtroppo ho incontrato un problema che non mi fa andare avanti neanche con Hello World.

Ho installato eclipse che funziona bene sia con python c/c++ arduino SDK, ma purtroppo Java mi da problemi
Da Error Log:

Message: Unhandled event loop exception

Ciao.....

nulla????

please

[ignazioc]

così è difficile darti una mano, intanto da eclipse se crei un nuovo progetto java e non scrivi nulla...compila? perché in realtà il progetto java di default di eclipse e già un hello world...
