hello,  
  
I want to call a webservice from mediator.  
i have done this from C# and it works (see E3SoapClient.cs)   
the service runns on a machine on my local network, so i made no proxy settings at the JVM Options.  
  
The WSDL is:

My sequence is:  
\<?xml version="1.0" encoding="UTF-8"?\>  
  
  
  
  
  
  
  
  
  
  
  
The \<params.xml\> file looks like:  
\<?xml version="1.0" encoding="windows-1252" ?\>   
  
  
content of the message is:  
----- Content -----  
\<?xml version='1.0' encoding='UTF-8'?\>  
-----\>  
  
When i execute the sequence, i get the following error:  
[slf5s.start]23 Feb 2005 17:34:55,706[slf5s.DATE] Thread-4[slf5s.THREAD] ERROR[slf5s.PRIORITY] xbd[slf5s.CATEGORY] - SagSequencer - SEQUENCER ERROR: sequence “[http://localhost:8080/slide/files/MediatorRepository/FlightCockpitReport/ArbortextAccessor.xml](http://localhost:8080/slide/files/MediatorRepository/FlightCockpitReport/ArbortextAccessor.xml)”, line 7, : com.softwareag.xbridge.exceptions.XException: XPath evaluation error[slf5s.MESSAGE]

i think, the problem is the way, i pass the parameters. the requironment of the webservice is to pass tehe parameters as “NameValuePair”, but some parameters are not “NameValue”.  
  
how can i pass the parameter “-p f=convert -p type=html -p file=$aptpath/e3/e3/e3demo.xml -o ConvertedServerFile.html” to mediator ?  
  
thx

Hi Hannes,  
  
The problem being reported is not related to the long parameter string. The error is an invalid XPath expression, e.g. xbd.soap.arg1.headers=“{Empty String}”. Expressions inside single curly braces are interpreted as XPath expressions by the sequencer engine, and this is clearly not valid.  
  
Hope this helps.  
  
Best regards,  
 Mike

hhi!  
  
i changed this, so that my sequence now is:  
  
  
  
  
the document from which the parameters are taken is:  
\<?xml version="1.0" encoding="windows-1252" ?\>   
  
  
  
  
  
  
i am still getting this exception logged:
