Using bouncycastle for S/MIME throws ClassCastException
Hi,
I've been trying to get some signatures verified using bouncycastle but nothing I do seems to work: I tried adding bouncycastle as a security provider (link below) but that throws an because it can't find javax.mail.Part
http://servicemix.apache.org/kernel/65-deploying-security-providers.html
If I also deploy javax.mail along with the bouncycastle jars I get a different error:
Caused by: java.lang.ClassCastException: com.sun.mail.handlers.multipart_mixed cannot be cast to javax.activation.DataContentHandler at org.apache.servicemix.specs.activation.OsgiMailcapCommandMap.createDataContentHandler(OsgiMailcapCommandMap.java:60)

I tried running the code in a SU or in a bundle and I always get the folowing exception:
Caused by: java.lang.ClassCastException: javax.mail.util.SharedByteArrayInputStream cannot be cast to javax.mail.internet.MimeMultipart

I took the code from one of the test cases that comes with bouncycastle and if I run it with JUnit it works. I only get this problem when I run it in ServiceMix. Here's the code:
if (Security.getProvider("BC") == null){
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
}
MimeMessage message = loadMessage("/basicAS2.message");
SMIMESigned s = new SMIMESigned((MimeMultipart)message.getContent()); // error occurs here
verifySigners(s.getCertificates(), s.getSignerInfos());
.....
private MimeMessage loadMessage(String name)
throws MessagingException, FileNotFoundException
{
Session session = Session.getDefaultInstance(System.getProperties(), null);
return new MimeMessage(session, getClass().getResourceAsStream(name));
}
