Need Expert openion on 'untrusted server cert chain'

Hai guys,
We are facing the 'untrusted server cert chain' problem.
And i know that
"client cannot trust the server, because it cannot find a certificate in it's keystore that has verified the server's certificate"
In Server (Weblogic 5.1) we are using the defalut weblogic democert.pem certificate. And using the keytool we have imported the democert.pem in our client. So now my client keystore is haveing the certificate which is used by the server(Weblogic 5.1).
I checked the keystore in client using the command

keytool -list

Even now we are facing the same(untrusted server cert chain) problem ?
Are u people sure that the problem is in Client side ?
Is there any Soultions avaliable for this problem ?

I'm assuming we're talking JSSE here... the did you import the certificate in "cacerts" rather than any other keystore? Somewhere in the server certificate chain, JSSE expects to find a Certificate Authority (CA) certificate from cacerts.
