UbuntuにJavaとAptana Studioを入れる

Javaを入れるのは簡単。コンソールで以下のコマンドを入力。

$ sudo apt-get install sun-java6-jdk << タブを押すと補完してくれる
$ java -version
java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

apt-get install sun-まで入力してタブを押すと「sun-」という名前で始まるアプリがあったら、その候補を出してくれるのがかっこいい。

Apatana Studioは以下のサイトからLinux用のZIPをダウンロードして、解凍して適当なディレクトリに配置して実行するだけ。
http://www.aptana.com/studio/download

$ cd aptana/ << Apatanaを解凍したディレクトリに移動
$ ./AptanaStudio

これで大体動く。だいたい。
メニューのHelp＞Aptana Studio Start Page..とかで開くブラウザを開こうとすると下の様なエラーが出る。解決方法がわからない。
通常このスタートページからRadRails等をインストールするのが簡単なのだけど、メニューの
Help＞Software Updats＞Find And Installを選択し、「Search for new features to install」を選択して次の画面に移動するとRadRailsやSubclipseを選択する画面が現れるので、ここからインストールすることも可能。
