title: How to enable the SUN security provider on IBM JDK J9 (java 1.6.0) built for WebSphere 8.5?
body: <p>I have a java program which runs perfectly well on SUN JRE 1.6. However, when I ran it on <code>IBM JDK J9 built for WebSphere 8.5</code>, it threw following exception:</p>
  
  <pre><code>java.security.NoSuchProviderException: Provider SUN is not available
  </code></pre>
  
  <p>I wrote a java program to list all available providers on IBM JDK J9 and found the SUN provider was missing, even though I have already included following line in the java.security file under. </p>
  
  <p><code>$JAVA_HOME/lib/security (i.e. /opt/IBM/WebSphere/AppServer/java/jre/lib/security)</code> :</p>
  
  <pre><code>security.provider.1=sun.security.provider.Sun
  </code></pre>
  
  <p>What else am I missing? Could someone please tell me how to enable / install this "SUN provider" on IBM JDK J9? Thank you so much!</p>
