Hi All
Can any one out there help me on SSL. Am trying to open a HTTPS URL that require a certificate from the client.
I have a certificate and it works with internet explorer.I have imported the same certificate to my keystore using keytool. I want to open the same URL in java.
In my java code I have pointed where my keystore in this snipet
System.setProperty("javax.net.ssl.keyStore","C:\\Temp\\mykeystore.jks");
System.setProperty("javax.net.ssl.keyStorePassword", "secure");
System.setProperty("java.protocol.handler.pkgs","javax.net.ssl");

Now my problem is when I try to open the URL in java I get this exception:

SunCertPathBuilderException: unable to find valid certification path to requested target



This is an error seen when using a test or self-signed certificate.
One side of the handshake is unable to verify the authenticity of the certificate. I'm betting you clicked a "accept certificate anyway" button when it worked in IE.

In your java client, you need some interactive code asking a user to accept the "test" certificate from the server. I know you have used System.setProperty(), but that code snippet, I think, is pulling a cert in for your client.

I think your answer is here:
