Hello,

we are getting below error while invoking API for access token from our code.

Wealready have imported required certificate in Java home.

Error is PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.

We are trying to test OpenID connect integration through OKTA. Below is the required code snippet.

HttpPost httppost = new HttpPost("https://dev-15411581.okta.com/oauth2/v1/token");

         httppost.setHeader("content-type", "application/x-www-form-urlencoded");

          postParameters = new ArrayList<NameValuePair>();

          postParameters.add(new BasicNameValuePair("grant_type", "authorization_code"));

          postParameters.add(new BasicNameValuePair("code", code));

          postParameters.add(new BasicNameValuePair("redirect_uri", "http://localhost:8080/Inside"));

          postParameters.add(new BasicNameValuePair("client_id", "0oa60ln2uiYjJWHBM5d7"));

          postParameters.add(new BasicNameValuePair("client_secret", "LDYhkim1E-PhqTu3lH0KIqHgsa9C-vdzxSvtjSQw"));

          postParameters.add(new BasicNameValuePair("code_verifier", "qjrzSW9gMiUgpUvqgEPE4_-8swvyCtfOVvg55o5S_es"));

          httppost.setEntity(new UrlEncodedFormEntity(postParameters, "UTF-8"));

Regards
