title: why got exception java.security.cert.CertificateException: Certificate has been denied
body: <p>when use jre1.7 to access https in <strong><em>some</em></strong> enviroment, it prompts java.security.cert.CertificateException: Certificate has been denied</p>
  
  <p>The applet is simple, such as</p>
  
  <p>applet codebase="https://xxx.xx.com/CheckJava.class"</p>
  
  <p>The error seems for security reason, jre doesn't allow any class or jar to download.</p>
  
  <p>if change the https to http on codebase, it works.</p>
  
  <p>Very appreciated if you could provide any clue to solve the issue.</p>
