I've got one tomcat 7 server(kind of like a web server) trying to talk to a tomcat 6 server(acting as a document server on another machine) over ssl and keep getting this error

java.security.cert.CertificateException: No name matching rarity64 found.

Where rarity64 is the name of the document server. I've tried exporting keys from both tomcats keystores and importing them into the others keystores using java keytool. I've even tried adding them to the other machines cacerts keystore.

I've also used internet explorer to import both keys into the other machine. But nothing I try works.

If it matters the real webserver is IIS 7.5, which the tomcat "webserver" talks too with arr, and they don't use SSL. But the problem seems to between the two tomcat servers
