title: Java Web Start: How to get rid of the warning icon?
body: <p>My java web start application always displays a warning icon in the top-right corner of the window. This is what I'm talking about:</p>
  
  <p><img src="https://i.stack.imgur.com/eqyRU.jpg" alt="Warning icon"></p>
  
  <p>I'd like to get rid of it. I have tried to sign my application without purchasing any certificate, just using <code>jarsigner</code>, but the icon is still there. In the other hand, if I don't sign the application at all, the icon is there as well. To be precise, i must say that my application runs in the basic sandbox.</p>
  
  <p>Can I get rid of this ugly icon ? I don't like it because I will target a public &amp; general audience, and some people might misinterpret its meaning. Would purchasing a certificate from an authority help in removing this icon ?</p>
  
  <p>And in case it is related to my question, this is my <code>jnlp</code> file:</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="UTF-8"?&gt;
      &lt;jnlp spec="1.0+" 
          codebase="http://localhost:8080/bin/" 
          href="xxx-webstart.jnlp"&gt;
          &lt;information&gt;
              &lt;title&gt;xxx.com&lt;/title&gt;
              &lt;vendor&gt;xxx.com&lt;/vendor&gt;
          &lt;/information&gt;
          &lt;resources&gt;
              &lt;!-- Application Resources --&gt;
              &lt;j2se version="1.6+"
                    href="http://java.sun.com/products/autodl/j2se"/&gt;
              &lt;jar href="xxx.jar" main="true" /&gt;
  
          &lt;/resources&gt;
          &lt;application-desc
               name="xxx.com"
               main-class="com.xxx.client.swing.main.MainClientSwing"
               width="400"
               height="400"&gt;
           &lt;/application-desc&gt;
           &lt;update check="always" policy="always"/&gt;
      &lt;/jnlp&gt;
  </code></pre>
