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.bouncycastle.tsp.TimeStampTokenInfo
According "Getting Started with iText - How to sign a PDF using iText", I have to use the BouncyCastle.
I downloaded the file: bcprov-jdk15on-147.jar from BouncyCastle download page.
And added to the project: Java Build Path/Libraries/Add External JARs...
I added the following line:
Security.addProvider(new BouncyCastleProvider());
When you run the example the same error occurs.
So I downloaded another file: bcpkix-jdk15on-147.jar entitled "PKIX/CMS/EAC/PKCS/OCSP/TSP/OPENSSL"
And added to the project: Java Build Path/Libraries/Add External JARs...
Now I have two Jars.
When you run the example the following error occurs:
Caused by: java.lang.ClassNotFoundException: org.bouncycastle.asn1.DEREncodable
I tried downloading the file "bcprov-ext-jdk15on-147.jar" but did not solve the problem.
I am using iText 5.2.1 and eclipse on Windows 7 64 bits.
