Instanciating an EntityDescriptor object

[Rod Widdowson]

This line (185) from ServiceTagSupport.java is the key:

 	spEntity =
HttpServletHelper.getRelyingPartyMetadata(loginContext.getRelyingPartyId(),
rpConfigMngr);

In your case you just need to shove in the entityID of the SP you do care
about in the place of loginContext.getRelyingPartyId().
