我有系統：ubuntu-9.04-amd64。我從官方默認存儲庫安裝IDE NetBeans 6.5。一切工作正常。純NetBeans不起作用
但是現在，我決定使用ubuntu-9.10-desktop-amd64。
我用我的硬盤格式化了部分：（/和/usr）。 /home依然如此。我已正確安裝ubuntu-9.10，正確（可能）安裝IDE NetBeans 6.5。
但現在，我甚至無法使用此IDE創建最簡單的Java應用程序。 如果我使用CommandLine編譯Java類，一切正常（~/javac someclass.java | java）。
如果我啓動IDE（NB 6.5），那麼文件 - >新建項目 - >這個新項目被創建，但不編譯：如果顯示放（F6）錯誤：

我能做些什麼來編譯最簡單的應用程序使用IDE。我必須做我的工作，請幫助我。
