The second arg to raise (i.e. the message) can be any object:

class ServiceNotFoundException < StandardError; end

begin
begin
raise "foo"
rescue Exception => e
raise ServiceNotFoundException, ["The service could not be contacted",
e]
end
rescue Exception => e_outer
puts e_outer
p e_outer.message
end

__END__

Output:

#<ServiceNotFoundException:0xb7d9b75c>
["The service could not be contacted", #<RuntimeError: foo>]
