title: Java popup saying applications contains both unsigned and signed code
body: <p>I am using Mac 10.7 running Java 1.7.0_21. I am trying to run a Java applet application that is signed and towards the end of the application I get a mixed mode security popup saying "Block potentially unsafe components from being run?". All the jars that I am using are signed.</p>
  
  <p>I am able to run the same applet application on Mac 10.6 running Java 6 and I don't get the mixed mode warning. I am also able to run the application on windows without the mixed mode warning coming up. </p>
  
  <p>Why do I get this keep getting this error when all my jars are signed?</p>
  
  <p>I googled mixed mode warning and found this link. </p>
  
  <p><a href="http://docs.oracle.com/javase/6/docs/technotes/guides/jweb/mixed_code.html#manifest" rel="noreferrer">http://docs.oracle.com/javase/6/docs/technotes/guides/jweb/mixed_code.html#manifest</a></p>
  
  <p>and after reading this link, I am a little confused. According to this link it looks like I need to have either "Trusted-Only" or "Trusted-Library" attribute mentioned inside my manifest file. I looked at my manifest file and they don't have these attributes so should I put them in or just the fact that the jars is signed should have been enough. </p>
  
  <p>Can someone please help me understand why I am getting this error even when everything is signed?</p>
