iText/BouncyCastle ClassNotFound org.bouncycastle.asn1.DEREncodable and org.bouncycastle.tsp.TimeStampTokenInfo

Question

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         


        

Answer 1

BouncyCastle libs are undergoing heavy API changes that broke the compatibility with other libs like iText.

Either

• use a previous version of BouncyCastle libs. Old versions can be found here. However, you'll have to find the right version of iText that was compatible with this particular version of BC.

• make your own build of iText (the SVN trunk has been fixed). iText can be build with Maven (there's a short readme file at the root of the SVN). Please note that it's at your own risk, there may be bugs in trunk.

• wait for the next version of iText. From my experience, iText releases come every couple of months, sometime more often, sometimes less. I'm not an iText committer though, so I can't give you any ETA.
