我正在尝试从cer文件创建签名。下面是我使用过的代码。我在X500Name初始化时收到错误。在调试模式下，代码可以工作，但是当我使用ant build将代码导出为jar文件时，它会产生错误。我使用了两个我已经与导出的jar压缩的库 一个。 bcprov-jdk15on-1.50.jar 湾bcpkix-jdk15on-1.50.jar
X509Certificate[] certs = (X509Certificate[]) request.getAttribute("javax.servlet.request.X509Certificate");
X500Name issuer = null;
try{
issuer = new X500Name(certs[0].getIssuerX500Principal().toString());
}catch(Throwable e){
e.printStackTrace();
}
错误：
