title: java.lang.NoClassDefFoundError: org.bouncycastle.jce.provider.BouncyCastleProvider
body: <p>I am facing issue in configuring Bouncy Castle with my <code>websphere</code>. I am working on pdf document signature and it requires dependency of Bouncy Castle. I am using <code>websphere v8.5</code>, <code>java 6</code> and <code>bcprov-jdk15on-1.47.jar</code></p>
  
  <p>Currently I have included this jar to my project lib and I am deploying it to WAS. So its throwing error:</p>
  
  <blockquote>
    <p>java.lang.NoClassDefFoundError: org.bouncycastle.jce.provider.BouncyCastleProvider.</p>
  </blockquote>
  
  <p>After getting this error I have tried to configure Bouncy Castle to <code>WAS</code> by putting <code>bcprov-jdk15on-1.47.jar</code> to <code>[WAS_HOME]/java/jre/lib/ext/</code> and updated <code>java.security</code>. After that when I am starting application server but server is not starting.</p>
  
  <p>Can you please provide me guidance on this? </p>
