I'm trying to understand ws-security signing and encryption. I've followed this guide. As mentioned I've Installed rampart, have created the relevant *.aar file successfully and deployed it in the tomcat servlet engine, added the org.bouncycastle.jce.provider.BouncyCastleProvider Bouncy Castle security provider (necessary for the public-key cryptography features used in the example code) to JVM security configuration (the lib/security/java.security file), added the Bouncy Castle JAR to both Axis2 installation's lib directory and Axis2 server application's WEB-INF/lib directory. (Which is the setup to run the given sample) But when running the example described, I am getting the following errors

How could I resolve this issue?
