Java Security

I have an application that connects https to a server and POSTs some data. That application works fine with one server but not with another. I get javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found.

Both servers have certificates signed by 2 different CAs. 1 is I think Thawte or Verisign (need confirmation with my admin) and the other I know for sure is Equifax. Of course Equifax is the least popular of the 2 and is not found in the cacerts keystore...

Now I downloaded the Equifax root certificate and installed in the default keystore by typing keytool -import -alias blabla -file c:\bla.cer and it imported correctly. I reran my app and I still got the same exception...

So I figure that the root cert for Equifax must be imported within the cacerts file in jre/lib/cacerts am I correct? Whats the default password for that keystore?

Thanks
