title: Installing ValiCert Class 3 PKI (X.509) certificate in jre's keystore on Red Hat Linux
body: <p>I have a web application deployed on Linux machine. Now, while generating pdf in web application I am getting following error:</p>
  
  <pre><code>javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
  </code></pre>
  
  <p>It seems that ValiCert Class 3 PKI (X.509) certificate is missing in jre's keystore. Does anyone have an idea of how to download it on Linux? Please provide the steps or link where I can get the required information?</p>
  
  <p>Thnaks in advance!</p>
