Certificate Verification - guidelines requested

My java app gets an X509 certificate out of an XML signature, and I
want to verify that the certificate is signed by any one of several
trusted CAs.

If we assume that all relevant CA certificates are stored in the
"cacerts" file in the local JDK, what is a simple way of verifying
that the original certificate is signed by one of these trusted CAs?

Please outline the steps my code should perform. (I couldn't find any
simple examples in the JDK documentation or on the web.)

Thanks very much!

Steve
