java.lang.NoClassDefFoundError with two BouncyCastle jars

I have included 2 BC jars into my project: bcpkix-jdk15on-1.47.jar and bcprov-jdk15on-157.jar.

As the first line in code I have added:

Security.addProvider(new BouncyCastleProvider());

Exception occurs on the line:

JcaPKCS10CertificationRequest csrNew = new JcaPKCS10CertificationRequest(request);

By the way it is imported: import org.bouncycastle.pkcs.jcajce.JcaPKCS10CertificationRequest;

But I am still getting :

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/bouncycastle/jcajce/JcaJceHelper at implementation.Util.generateCSR(Util.java:396)

NetBeans found class regularly, but when I run project exception happens.

Is there any way how could I regularly include both of these two BouncyCastle jars?

Error is coming for org/bouncycastle/jcajce/JcaJceHelper, not for org.bouncycastle.pkcs.jcajce.JcaPKCS10CertificationRequest.

Problem: versions of jar files you are using. bcpkix-jdk15on-1.47 is version 1.47, whereas bcprov-jdk15on-1.57 is version 1.57.

org/bouncycastle/jcajce/JcaJceHelper was available in bcprov-jdk15on-1.47 but it is not available in bcprov-jdk15on-1.57. In version 1.57, it is available as org/bouncycastle/jcajce/util/JcaJceHelper.

Netbeans is unable to detect the issue, because this issue would come only when you run the code. It will not be caught at compile time.

Solution: Yes, you can use both jars together. Just use the same version. Either use bcpkix-jdk15on-1.57 OR use bcprov-jdk15on-1.47.
