目的
リモートマシン onlnote2 から、CC/NET上のSBCである onlsbc1 を
ターゲットマシンとして、JavaRMIとJNIを使ったWebアプリケーションで
CAMAC read/write を実行する。
(1). 構成
(2). ソフトウェア
(3). 実行
--------------------------------------------------------------------
(1). 構成
テストに使用するマシンは onlnote2 と onlsbc1 である。 マシン onlnote2 は
Windows XP が動作している。 Java1.4.1_02 である。 一方 onlsbc1 は、
アドバンテク社のSBC、PCM-9370である。 このSBCは、CAMACコントローラ上に
装着されている。 SBC上で動作している OSは Red Hat Linux 8.0 で、コンパク
トフラッシュ上に構成してある。 Javaのバージョンは1.4.1_02 である。
(2). ソフトウェア
CC/NETのSBC、ホスト名onlsbc1のURLをリモートマシンからアクセスすることで
CAMACへの read/write が実行できるような例題を作る。
(2-1). サーバ側、onlsbc1.kek.jp
(2-1-1). Javaのチェック

Webブラウザ、IEで "http://onlsbc1.kek.jp/~inoue/hello.html" に
アクセスすると、"Hello World!"と表示される。
(2-1-4). ソフトウェア(その２)
CAMAC-JavaRMI4.htmlで使用したソフトをアプレット化して実行してみる。
(2-1-4A). GUI部のテスト
ClientImpl.java とGUIの部分のアプレットを一体にして動かしてみる。
注. この部分は、ホスト名 onlgw 上でテストした。
