我创建了一个 .jar 文件，其中包含我的签名数字证书，我想在我的项目中使用该文件，目前我如何使用它，它位于 &JAVA_HOME/jre7/lib/security 文件夹中。
提前感谢您的帮助:)。

如果 JAR 在您的类路径中，并且文件是位于根目录下的“foo.cert”，请执行此操作...
InputStream is = this.getClass().getResourceAsStream("/foo.cert");
CertificateFactory factory = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate) factory.generateCertificate( is);
