Connecting to HTTPS - unable to find valid certification path to requested target

[jamojo]

Hello everyone,

I am using the code below. It is working when I used this in Eclipse. What I did is to place the generated keystore from the InstallCert.class ( http://blogs.sun.com/andreas/resource/InstallCert.java ) to the latest JRE in the Program Files>Java

But when I deployed this class in the Tomcat/Bea its searching I am receiving this errors:

BEA Weblogic - HttpsConnection Exception: [Security:090477]Certificate chain received from - was not trusted causing SSL handshake failure.

TOMCAT: HttpsConnection Exception: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target.

Can you give me an idea on how to resolve this issue? Your replies are greatly appreciated.

Looking forward to your replies.

Thanks in Advance
