我正在将bcpkix-jdk15on-151.jar用于PEMParser.java类和oracle java 7，
但是在线
PEMParser pemRd =新的PEMParser（fRd）;
我受到追捧

at com.sarang.test.CertificateLoader.getCertificate(CertificateLoader.java:24)
at com.sarang.test.CertificateLoader.main(CertificateLoader.java:43)
我的源代码是：
public static X509Certificate getCertificate() throws IOException {
String pemfile = "/home/sarang07/keys/key1.crt";
java.security.cert.X509Certificate cert = null;
try {
FileReader fRd = new FileReader(pemfile);
PEMParser pemRd = new PEMParser(fRd);
Object o;
o = pemRd.readPemObject();
if (o instanceof java.security.cert.X509Certificate)
{
cert = (java.security.cert.X509Certificate) o;
} else {
throw new IOException("fail to load certificate from file " + pemfile);
}
} catch (FileNotFoundException e) {
throw new IOException("Can't find file " + pemfile);
}
return cert;
}
终于我从下面的代码片段中得到了解决方案...
public static java.security.cert.X509Certificate getCertificate(String pemfile) throws Exception
{
java.security.cert.X509Certificate cert = null;
try {
FileReader fRd = new FileReader(pemfile);
final PemReader certReader = new PemReader(fRd);
final PemObject certAsPemObject = certReader.readPemObject();
if (!certAsPemObject.getType().equalsIgnoreCase("CERTIFICATE")) {
throw new Exception("Certificate file does not contain a certificate but a " + certAsPemObject.getType());
}
final byte[] x509Data = certAsPemObject.getContent();
final CertificateFactory fact = CertificateFactory.getInstance("X509");
cert = (X509Certificate) fact.generateCertificate(new ByteArrayInputStream(x509Data));
if (!(cert instanceof X509Certificate)) {
throw new Exception("Certificate file does not contain an X509 certificate");
}
} catch (FileNotFoundException e) {
throw new IOException("Can't find file " + pemfile);
}
return cert;
}
