こんにちは、APplet を含む Web アプリケーションを作成し、このタグを使用して Html ページでアプレットを開始します

<applet codebase="http://localhost:8084/WebForSpark" code="AppletBroadcaster.ZkusebniApplet" archive="AppletBroadcaster.jar, jave.jar " width="500" height="500"></applet>

アプレットで外部ライブラリ javae.jar を使用する必要があるため、このファイルを Web プロジェクトの bulid/web フォルダーに手動で追加しました。だから、すべてうまくいきます。私のwebproject Javaコンソールを実行すると、これを書きます

Basic: Plugin2ClassLoader.getPermissions CeilingPolicy allPerms

したがって、build/web フォルダー内の javae.jar が作成されたことは明らかです。

しかし、jave.jar からいくつかの操作を実行するためのボタンをアプレットにプッシュすると、javaconsole はこれを書き込みます

javae.jarがすべきことはすべて正しく行われていますが、私の質問は、私のjave.jarが入っているときにlib/jave.jarが何度も呼び出されるのはなぜですか

http://localhost:8084/WebForSpark/

アプレットの起動中に正常にロードされました... lib/jave.jar を呼び出さないために何ができますか? また、なぜ呼び出されるのですか? どうもありがとう

現在のアプレット要素はに要約されます。

<applet
    codebase="http://localhost:8084/WebForSpark"
    code="AppletBroadcaster.ZkusebniApplet"
    archive="AppletBroadcaster.jar, jave.jar"
    width="500"
    height="500">
</applet>

これにより、JREは同じパス（またはパッケージによってはサブディレクトリ）からその中にあるすべてのクラスでJarを検索しますhttp://localhost:8084/WebForSpark（失敗します）。jave.jarは実際には別の場所だと思うので、属性archiveは次のようになります。

<applet
    codebase="http://localhost:8084/WebForSpark"
    code="AppletBroadcaster.ZkusebniApplet"
    archive="AppletBroadcaster.jar, /path/to/jave.jar"
    width="500"
    height="500">
</applet>

どこ/path/to/にあるか、/lib/または他のパス。
