as2-servlet: JCE cannot authenticate the provider BC

[yusufbata]

I'm getting the following error when trying to receive a message using as2-servlet:

ERROR [com.helger.as2lib.processor.receiver.net.AS2ReceiverHandler] (default task-8) Error decrypting [<MY-JUNIT-TEST-CASE-phax-as2-lib-31072018232014+0200-1843@OpenAS2B_OID_OpenAS2A_OID>]: JCE cannot authenticate the provider BC

I've tried a number of options found online without any success. Any ideas on how to resolve this?

Thanks!

Hi. I'm on vacation this week so I only have quick ideas: is BouncyCastle in your classpath? If yes which version? The latest version of BC is 1.60.

Thanks for the quick reply!

I've packaged BouncyCastle version 1.59, as well as 1.60 - same issue occurs with both.

Do you have a working example project that contains as2-servlet (i.e. a deployable war)?

Thanks!

What does packaged mean? Maven assembly plugin and BC does not work, because BC is a signed JAR! Also uberjar and all that stuff must be handled with care. A sgandalone example for using as2-servlet is available and will be published after my vacation next week. So stay tuned

Did the hint on packaging help you? Did this solve your issue?
https://vzurczak.wordpress.com/2017/09/04/bouncycastle-osgi-and-uber-jars/ contains the explanation.
Try e.g. https://stackoverflow.com/questions/17658831/how-can-i-exclude-dsa-and-sf-files-from-shaded-jar for a possibility to exclude *.SF, .DSA,.RSA

Thanks Philip - excluded the bouncy castle dependencies from the war and its working perfectly.

Great that it works :)
