目的
並列CAMACで使用するSBC上のLinuxシステムでは、Javaが利用できる必要が
ある。 理由は、並列CAMACでは複数のCAMACコントローラ中のSBCとこれら
のCAMACコントローラからデータを集めるDAQコントロールマシンとの間で
分散オブジェクトシステムを構築することを想定しているからである。
JavaRMI、JavaIDL さらにはHORBなどが実行できる基本的なものとして
Javaをインストールする。
(1). Java v1.4.1 の入手
(2). Javaのインストール
(3). 設定
--------------------------------------------------------------------
(1). Java v1.4.1 の入手
J2SE v1.4.1 のダウンロードサイトから、"SDK Linux 自己解凍ファイル" を
入手する。

要件 3.
"英語ロケールでの J2SDK 1.4.1 Linux 版のほとんどのテストは、Red Hat 7.2
上で、カーネルパッチ 2.4.9-31 を使用して行われています。英語以外のロケー
ルでのほとんどのテストは、Red Hat 7.1 上で行われています。ただし、以下の
Linux オペレーティングシステムに対しては、J2SDK 1.4.1 のテストは限られた
ものしか行われていません。
Caldera Open Linux 3.1 (kernel 2.4.2, glibc 2.2.1)

compat-libstdc++-6.21-2.9.0.0.i386.rpm を手動でインストールする必要が
あります。"
