【问题描述】:
我正在尝试使用带有文档示例的 iText 5.5.0 进行签名:
private static void pdfSign(String srcFile, String dstFile) throws Exception
KeyStore ks = KeyStore.getInstance("pkcs12", "BC");
ks.load(new FileInputStream(PFX_ROUTE), PFX_PASSPHRASE);
String alias = (String)ks.aliases().nextElement();
PrivateKey pk = (PrivateKey)ks.getKey(alias, KEY_PASSPHRASE);
Certificate[] chain = ks.getCertificateChain(alias);
// reader and stamper
PdfReader reader = new PdfReader(srcFile);
PdfStamper stamper = PdfStamper.createSignature(reader, new FileOutputStream(dstFile), '\0');
// appearance
PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
appearance.setVisibleSignature(SIGNFIELD_NAME);
appearance.setReason("Test");
appearance.setLocation("TestLocation");
ExternalSignature es = new PrivateKeySignature(pk, "SHA-1", "BC");
ExternalDigest digest = new BouncyCastleDigest();
MakeSignature.signDetached(appearance, digest, es, chain, null, null, null, 0, CryptoStandard.CMS);
}
我收到以下错误。

我的java版本是:
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
我正在使用 Netbeans IDE 7.4 和 JCE Unlimited Strength Jurisdiction Policy Files 替换我的 /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre/lib/security 路径。
我已经从我的终端尝试了:“ulimit -c unlimited”命令。
【问题讨论】:
-
请出示
hs_err_pid602.log的内容。 -
Hhmmm,
sun.misc.Unsafe.copyMemory似乎经常参与有趣的 JVM 崩溃。您可能想尝试不同的PdfReader构造函数,例如首先将文件读入内存,然后使用带有byte[]参数的构造函数。 -
确实试过了,还是一样的错误。
-
或者,您是否尝试过不同的 jvm 版本?由于 iTextin 您的用例仅使用标准 api 调用,这很可能是 Java 错误。
