title: Why does Java tell me my applet contains both signed and unsigned code?
body: <p>My signed Java applet has been running fine until Java update 19.  Now some but not all of our users on Java Update 19 report a java security message stating that our applet contains both signed and unsigned code.</p>
  
  <p>The process for creating our applet is as follows:</p>
  
  <ol>
  <li>Clean and Build the applet project in Netbeans IDE.</li>
  <li>Open the Applet jar file in WinRAR and add the required mysql JDBC driver .class files to the jar file.</li>
  <li>Sign the applet jar file.</li>
  </ol>
  
  <p>Can someone please tell me how to determine what code is signed and what code is not signed in our applet?  Is there a better way to include the mysql JDBC driver jar file in our applet other than copying the jar file contents into our applet jar file?</p>
  
  <p>Thanks</p>
