Put this library in your classpath bcprov-jdk15on-1.47.jar

UPDATE

Mind your bouncy castle dependencies version according to the IText version you are using. To double check it with maven repositories. eg. here or here

+1; but please inspect the maven pom for the preferred Bouncy Castle version. E.g. version 5.5.0 documents a dependency on BC 1.49. – mkl Mar 31 '14 at 10:16
