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:
<?xml version="1.0" encoding="utf-8"?>

</wsdl:definitions>
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:

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

E3SoapClient.cs (9.72 KB)
this is the way, it look like, when i’m calling the Weservice from visual Studio:
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:
