Content is not allowed in prolog

hi all,

 

i have web services written in cf has 2 input parameters.   1 parameter integer , other parameter xml string.  in application calls web service, passing wddx packet second parameter.

 

the trouble is, keep on getting following error message.

 

         <faultcode>soapenv:server.userexception</faultcode>
         <faultstring>coldfusion.xml.rpc.cfcinvocationexception: [coldfusion.wddx.wddxdeserializationexception : wddx packet parse error @ line 1, column 1. content not allowed in prolog..]</faultstring>

 

i took @ ben nadel's blog on problem.  have tried trimming out excessive spaces did not solve problem.  had looped through xml string see if bom problem; bom not there. , yet, above message keeps coming on.  can point me right directions in solving error?

 

thanks advance,

monte
