bouncycastle bcprov-jdk15on-1.56

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

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

Hi, can we upgrade the bouncy castle with a newer version, as we are using two different libraries from bouncy castle and the one actually collides with the one provided by Axon Ivy

Until 7.0 the library is used to provide Webservice.process API via SOAP.

If you don't provide webservices, you can replace it.
If you use ivy to provide webservices, you can test whether authentication mechanism is still working with another bcprov library...

With 7.1 the library is no longer shipped with the product and therefore no problems exists.

What version are you using?

I'm just guessing but I think you can replace the bouncycastle library if you use no webservice processes at all or if you have only such with HTTPBasic or Container authentication: https://developer.axonivy.com/doc/latest/DesignerGuideHtml/ivy.processmodeling.html#ivy-processmodels-elements-tabs-wsprocess
