title: Certificate Loading Issue
body: <p>I have developed one applet and I am finding a strange behavior.</p>
  
  <p>This is for implemented security based application which build in GWT, Hibernate and Spring.</p>
  
  <p>The applet is mainly accessing browser certificates and using it for encryption and decryption of data.</p>
  
  <p>It is working fine on all the system but I don't know one client machine I am finding a strange behavior.</p>
  
  <p><strong>When I login in Internet Explorer. The applet loading stops at following point and then closes down automatically.</strong></p>
  
  <p>Error in applet console saying:</p>
  
  <blockquote>

  <p><strong>Removed Blacklist Revocation</strong> Check and Trusted Library check but there is no impact. (They are passing through well), </p>
  
  <p>If I open any sample applet from <a href="http://csis.pace.edu/~bergin/Java/applets.htm" rel="nofollow">http://csis.pace.edu/~bergin/Java/applets.htm</a> 
  it stops on following line</p>
  
  <pre><code>    basic: Plugin2ClassLoader.isTrustedByPolicy called 
      basic: Plugin2ClassLoader.isTrustedByPolicy returns false 
  </code></pre>
  
  <p><strong>Behaviour on all three browsers.</strong></p>
  
  <blockquote>
    <ol>
    <li>Firefox and Chrome : Does not load at all.</li>
    <li>IE : First time does not load when hit refresh it loads.</li>
    </ol>
