You must have something like :
<Connector port="8443" address="${jboss.bind.address}"
maxThreads="100" strategy="ms" maxHttpHeaderSize="8192"
emptySessionPath="true"
scheme="https" secure="true" clientAuth="false"
keystoreFile="${jboss.server.home.dir}/conf/jboss-cert.p12" keystoreType="PKCS12"
keystorePass="exportPassword" sslProtocol = "TLS" />
Note, I used my own CA tool to create the pkcs12 cert file.
