java - Java 7 update 25 で Java Web Start を起動できない

Question

deploy Java Web Startとして Java Web Start アプリケーションをデプロイしようとしています

しかし、アプリケーションを起動すると、例外が発生しました:

java.io.IOException: Cannot find cached resource for URL: http://nguyennguyen1647:8080/myweb/byte-viewer-1.0.0.jar

私の問題は、私のjarファイルが自己署名されていることだと思います。証明書付きのjarファイルに署名する方法を教えてください。

前もって感謝します！
