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

Question

I am running an application in Eclipse locally. It tries to connect to an external URL to fetch some data. This application works fine from browser, but when I try the same from Eclipse as localhost, I get the below error:

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
    at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:456)
    at sun.security.validator.PKIXValidator.engineValidate(PKIXValidator.java:323)
    at sun.security.validator.Validator.validate(Validator.java:271)

Many solutions, have mentioned to add the URL certificate from the browser using keytool. This application shows "This site does not have a certificate.". The application URL does not have a certificate.

In this case, how can I fix this issue without a certificate to install?

looks like you are running any java based application on a web server(eg Tomcat) with HTTPS enabled.

If you donot have signed any self certificate, then following link can help: How to configure Tomcat to support SSL or https
