i searched the archive at http://xmlrpc.helma.org/archives/xmlrpc/
there is one message which is related to my problem. somebody says that it is fixed in the apache version of xml-rpc. but it seems not to be, because the null value is not in the original xml-rpc spec. Is there another archive? what i now do is to uncomment the line ' // workaround for Frontier bug' in XMLRPCServer.writeRespone. think that would fix the problem. daniel.
