title: Capture java app traffic with fiddler
body: <p>I know this question has been asked and answered a lot of times but I really need a little help with my application.
  First of all I am trying to capture traffic from an existing java app (I don't have the source code to modify it).
  What I did so far :</p>
  
  <ul>
  <li>I have exported the root certificate from tools-->Options-->Actions</li>
  <li>I have run \bin\keytool.exe -import -file C:\Users\\Desktop\FiddlerRoot.cer
  -keystore FiddlerKeystore -alias Fiddler</li>
  <li>I download Eclipse and run the java app from run-->External tools-->external Tools Configuration and put as location:JDK_HOME\bin\java.exe and working directory my app_dir</li>
  <li><p>I put as arguments :</p>
  
  <p>-DproxySet=true<br>
  -DproxyHost=127.0.0.1
  -DproxyPort=8888<br>
  -Djavax.net.ssl.trustStore=app_dir\FiddlerKeystore
  -Djavax.net.ssl.trustStorePassword=key<br>
  -jar app.jar</p></li>
  </ul>
  
  <p>I still can't capture any traffic from fiddler.
  Can someone tell me what am I doing wrong?</p>
