[Freefluo-users] trouble with multiple outputs

[Ohler, N. T. <Nat...@hm...>]

I have a web service returning multiple outputs. I can only get freefluo =
to read the first one.=20

I have three files to work with: The workflow xml, the wsdl, and the web =
service.

I have the web service returning two parts, and the message looks like:
-------------------------------------------------------------------------=
--
<?xml version=3D"1.0" encoding=3D"UTF-8"?><SOAP-ENV:Envelope =
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance" =
xmlns:SOAP-ENC=3D"http://schemas.xmlsoap.org/soap/encoding/" =
xmlns:SOAP-ENV=3D"http://schemas.xmlsoap.org/soap/envelope/" =
xmlns:xsd=3D"http://www.w3.org/2001/XMLSchema" =
SOAP-ENV:encodingStyle=3D"http://schemas.xmlsoap.org/soap/encoding/"><SOA=
P-ENV:Body><namesp1:getemmaResponse =
xmlns:namesp1=3D"urn:getemma"><stderr xsi:type=3D"xsd:string">standard =
error message</stderr><stdout xsi:type=3D"xsd:string">standard output =
message</stdout></namesp1:getemmaResponse></SOAP-ENV:Body></SOAP-ENV:Enve=
lope>
-------------------------------------------------------------------------=
--


If I set the wsdl to claim the web service only has one response (when =
the web service really has two), and the workflow xml to only look for =
one:
-------------------------------------------------------------------------=
--
<message name=3D"emmaResponse">
        <part name=3D"stdout" type=3D"xsd:string"/>
</message>
-------------------------------------------------------------------------=
--
  <s:link source=3D"getemma:stdout" sink=3D"stdout" />
  <s:sink name=3D"stdout" />
-------------------------------------------------------------------------=
--
Then my output file saves only the first response, even if the names =
don't match! (It saves the part named stderr as stdout, and discards the =
part named stdout).




If I set the wsdl and workflow for both outputs:
-------------------------------------------------------------------------=
--
<message name=3D"emmaResponse">
        <part name=3D"stdout" type=3D"xsd:string"/>
        <part name=3D"stderr" type=3D"xsd:string"/>
</message>
-------------------------------------------------------------------------=
--
  <s:link source=3D"getemma:stdout" sink=3D"stdout" />
  <s:link source=3D"getemma:stderr" sink=3D"stderr" />
  <s:sink name=3D"stderr" />
  <s:sink name=3D"stdout" />
-------------------------------------------------------------------------=
--


Then the output file only gets this much written:
-------------------------------------------------------------------------=
--
<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<b:dataThingMap =
xmlns:b=3D"http://org.embl.ebi.escience/baclava/0.1alpha" />
-------------------------------------------------------------------------=
--

And the std.err.log reports:
-------------------------------------------------------------------------=
--
java.lang.RuntimeException: Attempt to create a null data object, =
definitely not allowed!
at org.embl.ebi.escience.baclava.DataThing.<init>(DataThing.java:231)
at =
org.embl.ebi.escience.scuflworkers.wsdl.WSDLInvocationTask.execute(WSDLIn=
vocationTask.java:196)
-------------------------------------------------------------------------=
--



I would appreciate any ideas where I'm going wrong with these forms. I =
can forward the whole xml files if desired, just wasn't certain how the =
mailling list would handle them, and was trying to keep this somewhat =
brief.

Thanks for any help
