I\'m trying to use iText Java. When you run the example \"how to sign\" the following error occurs:
Caused by: java.lang.ClassNotFoundException: org.bouncyca
from version of bcprov-jdk15on-147, class of DEREncodable is no longer exist under the path of org.bouncycastle.asn1. You can use version before 146 (including 146) to resolve this question.
