開発/テスト サイトでは実行されていませんが、運用サイトでは正常に動作する Web アプリケーションにアプレットがあります。この問題は、Mac Lion のブラウザーからサイトにアクセスしている場合にのみ発生します。MSWin クライアントから実行されているブラウザー (IE、FF、Safari、Opera) には問題はありません。
開発サイトと本番サイトの違いは、本番サイトには SSL 用に購入したサイト証明書があるのに対し、開発サイトには自己署名証明書があることです。SSL を使用しない場合、アプレットは開発サイトでも正常に動作します。
アプリケーションは IIS 7 によって提供されています。Java プラグインが有効になっています (そうしないと、開発ボックスで http または運用ボックスで ssl を使用してアプレットを実行できません)。
アプレット jar 自体は、購入した証明書で署名されています。Web ページは、JavaScript を使用してアプレットと対話します。
HTML ページには、アプレットの次のコードが含まれています。
<object name="Previewer"
class="java-applet"
classid="java:com.[omitted].template.TemplateViewer.class"
type="application/x-java-applet"
archive="../Template/tv/TemplateViewer.jar"
height="425" width="270">
<param name="MAYSCRIPT" value="true" />
<param name="scriptable" value="true" />
<param name="archive" value="../Template/tv/TemplateViewer.jar" />
<!-- following parameters are used by the applet itself -->
<param name="TEMPLATE" value="[url omitted]" />
<param name="VERSION" value="1.7" />
<param name="AREA" value="AreaName" />
<param name="CUSTOMIZABLE" value="Y" />
<param name="BACKGROUND" value="[url omitted]" />
<param name="SHOWDROPDOWN" value="false" />
</object>
Java コンソールは、スタック トレースを提供します (質問の最後にリストされています)。
ClassNotFound 例外がアプレット クラス ローダーによってスローされているのを確認しました。これは、「署名アルゴリズムの不一致」を伴う CertificateException が原因のようです。
数時間の Google の後、私は空白になり、ここで「既に回答がある可能性のある質問」と「同様の質問」をすべて確認しましたが、何の啓発もありませんでした。
私が推測できるのは、一部のモバイル デバイスが SSL によって提供されるメディアを提供することに敏感であるのと同様に、自己署名証明書を使用してサイトにアクセスすることによって、この問題が何らかの原因で発生していることです。
今質問：
この問題の原因は何ですか?
それを修正するために何ができますか?
スタック トレースを含むコンソール ログは次のとおりです。
