Question

当我尝试获取TimeStamp响应时，我遇到了错误。我使用的代码是：

PdfPKCS7 sgn = new PdfPKCS7(pk, chain, null, "SHA256", null, false);
        InputStream data = sap.getRangeStream();
        MessageDigest messageDigest = MessageDigest.getInstance("SHA256",
                "BC");
        byte buf[] = new byte[8192];
        int n;
        while ((n = data.read(buf)) > 0) {
            messageDigest.update(buf, 0, n);
        }
        byte hash[] = messageDigest.digest();
        Calendar cal = Calendar.getInstance();
        byte[] ocsp = null;

        byte sh[] = sgn.getAuthenticatedAttributeBytes(hash, cal, ocsp);
        sgn.update(sh, 0, sh.length);
        byte[] encodedSig = sgn.getEncodedPKCS7(hash, cal, tsc, ocsp);
        System.out.println("contentEstimated: " + (contentEstimated + 2));
        System.out.println("encodedSig.length: " + encodedSig.length);

该行出现错误： byte sh [] = sgn.getAuthenticatedAttributeBytes（hash，cal，ocsp）;

错误是：

我显示了相同的错误（http://itext-general.2136553.n4.nabble.com/Nosuchmethod-error-for-bouncy-castle-td3492864.html），但我无法做到这一点。我知道问题出在bouncycastle libaries上。我尝试使用这个版本：

bcprov-jdk15-1.46.jar
bcmail-jdk15-1.46.jar
itextpdf-5.1.2.jar

其他的bcprov-jdk（16-146,14-146,15-137,15-1.43）。

任何人都知道我做错了什么？非常感谢。

感谢您的时间。

我解决了这个问题，将bcprov-jdk，bcmail-jdk和bctsp-jdk版本15-146替换为15-143版本。

java.lang.NoSuchMethodError：org.bouncycastle.asn1.DERSequence。<init>（Lorg / bouncycastle / asn1 / DEREncodableVector;）V </init>
