Nosuchmethod error for bouncy castle

Hi, i followed the code snippet provided in iText in Action book. and when i run the following code, i get a java.lang.NoSuchMethodError: org.bouncycastle.asn1.DERSequence.<init>(Lorg/bouncycastle/asn1/DEREncodableVector;)V exception

KeyStore ks = KeyStore.getInstance("pkcs12");
String alias = "aprivatekey";
FileInputStream fis = new FileInputStream(keystoreFilePath);
BufferedInputStream bufin = new BufferedInputStream(fis);
ks.load(bufin, password.toCharArray());
PrivateKey pk = (PrivateKey)ks.getKey(alias, password.toCharArray());
Certificate[] chain = ks.getCertificateChain(alias);

PdfReader reader = new PdfReader(filename1);
PdfStamper stamper = PdfStamper.createSignature(reader, new FileOutputStream(filename2), '\0', null, true);
PdfSignatureAppearance appearance = stamper.getSignatureAppearance();
appearance.setVisibleSignature("mySig");
appearance.setReason("It's something");
appearance.setLocation("MD");
appearance.setCrypto(pk, chain, null, PdfSignatureAppearance.WINCER_SIGNED); appearance.setCertificationLevel(PdfSignatureAppearance.CERTIFIED_NO_CHANGES_ALLOWED);

stamper.close();
reader.close();

The code throws the exception when calling stamper.close();

Another post talks about bouncycastle version. I tried using bouncycastle jar version 1.46 and 1.38. Same exception. What would be the exact version of bouncycastle that will support iText?

Why is the exception being thrown?

Thanks in advance.

Re: Nosuchmethod error for bouncy castle

Hello,

I remember coming across a similar error and I use 1.43 to avoid it.

Re: Nosuchmethod error for bouncy castle

I remember that too.

http://www.bouncycastle.org/download/bcmail-jdk16-143.jar

I just had to replace the 6 in 146 from the current version with the 3. OK, one would argue for a checksum.
