java - PKIX path building failed in Eclipse

Question

i'm working with Liferay and i'm using eclipse, and running a client/server model, using an encrypted socket (SSL).

Currently, my application is running the client/server connection ok when I run the application in batch mode but when i try to start the server in Eclipse the application is giving me error

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
at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)

I already use the InstallCert.java and copy the jssecacerts into

%JAVA_HOME%/jdk_version/jre/lib/security

but is still giving me errors. I've also checked the certificate (keytool -v -list) and installed manually in the root CAs trusted. What can be the problem? Thanks!

Please refer this answer for your reference.

No need of passing any VM arguments after you successfully installed certificate of the site which is giving you PKIX error!

But key is to find JRE which is giving you this error! So make sure about 2 things:

1. you install certificate to cacerts file of JRE which Eclipse is using
2. certificate is root certificate
