動作テスト用ファイル,PHP,Perl,Java,PostgreSQL,MySQL,DB,JSP,サーブレット - サンプル

更新:

動作テスト用ファイル,PHP,Perl,Java,PostgreSQL,MySQL,DB,JSP,サーブレットのサンプル。

はじめに
・このページは、サーバ上でPHP、Perl、データベースなどの表示のテストをするための簡単なサンプルファイルです。
・Linux Fedora、RedHat、Apache、tomcatなどのシステム上での動作確認を行えます。
・新しい環境でウェブアプリケーションを動作させる場合、
 まず簡単なサンプルが動作するか試すことをオススメします。
	・HTML
	・Perl、Perl + PostgreSQL、Perl + MySQL
	・PHP、PHP + PostgreSQL、PHP + MySQL
	・Java、Java + PostgreSQL、Java + MySQL
