title: Force java web start to use a proxy like Fiddler without touching code
body: <p>For a automatic software project i need some requests and responses from a Java Web Start application.</p>
  
  <p>So i installed Fiddler Web Debugger and then i tried to use this fiddler proxy to sniff all requests.</p>
  
  <p>The problem is the Java Web Start application.</p>
  
  <p>I added this to the .jnlp file and hoped that it works... It doesnt! :(</p>
  
  <pre><code>  &lt;property name="http.proxyHost" value="127.0.0.1"/&gt;
    &lt;property name="http.proxyPort" value="8888"/&gt;
  </code></pre>
  
  <p>The application would ignore it.</p>
  
  <p>Then i  tried to set up the Java settings.</p>
  
  <p><img src="https://i.stack.imgur.com/PC5Uz.png" alt="network settings for java"></p>
  
  <p>It doesnt works, too ;(</p>
  
  <p>Wireshark cant decrypt the https/ssl requests...</p>
  
  <p>What could i do to decrypt the requests or to read the requests OR to let use the java web start application the fiddler proxy.</p>
  
  <p>Why java cant use the system proxy? >.></p>
