Hello Ivy Team,

I would like to sign PDF files using apache pdfbox. Apache pdfbox requires the bcprov-jdk15on for encryption and signing. When I try to run the signing example (https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/signature/) i get a Exception in thread "main" java.lang.SecurityException: class "org.bouncycastle.asn1.ASN1Primitive"'s signer information does not match signer information of other classes in the same package at java.lang.ClassLoader.checkCerts(Unknown Source)

I think this exception occurs because the designer has a bcprov-jdk15-1.45.jar already included, but this is not the jar pdfbox expects. (bcprov-jdk15 and bcprov-jdk15on)

When I try to delete this jar it is automatically recreated on startup.

Could you please help me to solve this problem.

I am using the ivy Designer 5.1.8

Thank you and best regards Florian

have you tried to put the JAR to jre/lib/ext ?

You could try to repack the bouncycastle library, so that it will be available with another namespace. See http://repackage.org/

Or the HSQL thread, where this solution was applied to the HSQL library: http://answers.axonivy.com/questions/960/use-the-latest-hsqldb-within-my-project
