title: Avoid security level blocking without adding url in exception site list
body: <p>I have created Java <code>signed applet</code>, it runs perfectly if I set my <strong>Java(JRE 8) security level</strong> <strong><em>high</em></strong> and add my <em>site url</em> in <em>exception site list</em>.</p>
  
  <p>But if we do not add site url in exception site list, java security exception comes as explained here : <a href="https://blogs.oracle.com/java-platform-group/entry/upcoming_exception_site_list_in" rel="nofollow noreferrer">add url in exception site list</a></p>
  
  <p>I have created a signed applet using a third part certificate.</p>
  
  <p>Here is my manifest file after creating signed applet:</p>
  
  <p>Is there any option available to <em>avoid these security blocking popups</em> by adding some changes in manifest file while creating signed applet, or any script, java code to avoid these popups without adding site url in exception site list?</p>
  
  <p>Or is it really <strong>mandatory from Java</strong> that <strong>we must need to add site url in exception site list to avoid such blocking error.</strong></p>
  
  <p><strong>Basically is there any option available to add our url in exception site list through manifest file or any Java code ?</strong>

  <p>Is it mandatory if I want to sign my applet using signed certificate then it must be a code signing certificate? wildcard or ssl certificate will not work?</p>
  
  <p>As I am getting self signed applet block issue though I have signed my applet with wildcard certificate.</p>
