Revision as of 14:15, 9 November 2007
Web Services Stuff
demo.targetprocess.com
I am connected to two different WebServices that use the same name.
http://demo.targetprocess.com/Services/IterationService.asmx http://demo.targetprocess.com/Services/UserStoryService.asmx
They have the same name and method:
http://targetprocess.com/RetrieveAllForProject
Stubs for these services were created with wsdl2py -b url
One returns IterationDTO and one UserStoryDTO.
When i create a class that uses both webservices i get into trouble. The one i import first creates a object for the name/method. When the other one is imported it doesn't create an object or it simply uses the first one created.
AttributeError: 'ArrayOfUserStoryDTO_Holder' object has no attribute 'IterationDTO'
It should be ArrayofIterationDTO_Holder, but since i imported UserStory service first its ArrayOfUserStoryDTO_Holder.
WSDL-1.1 are full of errors
The schemas for WSDL-1.1 are full of errors, so they aren't useful for validation. I tried cleaning them up but it's just too much to do right now.
Try this:
%python -c "from ZSI.wstools.WSDLTools import WSDLReader as wsr; print wsr().loadFromFile('INFOSearch.wsdl')"
should give you a more informative error.

Echo Server
Your client is a problem. Twisted is a little different. Give this script a shot, also since you're using the "-b" option take advantage of the properties as I do below. I ran this w/o problems.

Raw XML
posting solution to list:
I think you need to use a DOM node.
Something like this from "test/wsdl2py/test_NVOAdmin.py"
input = open('wsdl/nvo-admin.wsdl').read()
reader = PyExpat.Reader()
dom = reader.fromString(input)
dnode = _child_elements(dom)[0]
tnode = _child_elements(dnode)[0]
snode = _child_elements(tnode)[0]
msg.DSQueryRegistryResult.Schema = snode
Here is what happens if you specify a str:
1276 def cb(self, elt, sw, pyobj, unsuppressedPrefixes=[]): 1277 """pyobj -- xml.dom.Node.ELEMENT_NODE 1278 """ 1279 #if sw.Known(pyobj): 1280 # return 1281 1282 if type(pyobj) in _stringtypes: 1283 elt.createAppendTextNode(pyobj) 1284 return 1285
So if you dump a DOM node into this function (XML.cb), it will behave differently (no escapes).

I found a question (dated 2007-05-31) about sending raw xml with ZSI, and the answer (dated 2007-06-01) was that you needed to grab the latest ZSI source to make TC.XML work. I have done that, but ZSI is still translating the > in my raw xml to >
Is there a way to send the raw xml through ZSI without that translation occurring?
Thank you very much for your help.
ZSI.TC
the instances you're comparing are equivalent, both are legal XML, and both follow the schema.
Now if .NET doesn't digest ZSI output, I'll hold my nose and direct you to a solution or two.
1) You may try declaring all the namespaces in the envelope using the "nsdict" parameter.
2) You could replace the ElementProxy with one I posted on the list a while back that did this same thing.
Check out this page:

Hi Eric,
The documentation for ZSI.TC is really confusing IMHO. From what I can tell, TC does not determine how the namespaces are printed out. I have not dealt with the requests myself (only the server responses), but to change how the response was printed, I eventually had to dig into the code, particularly within the _Dispatch method found in dispatch.py . For the request, you might have to dig in client.py in the _Binding.Send method. Look for variables called tc. Sorry I can't be of more help, but please let me know if you find out how to do this.
Cheers,
Julius

I saw your response yesterday about ZSI.TC.Struct to the pywebsvcs newsgroup. You said:
An example would be
My_Class.typecode = ZSI.TC.Struct(My_Class,
[ ZSI.TC.String('my_var'),
ZSI.TC.Array((' http://www.w3.org/2001/XMLSchema ',
'string[]'), ZSI.TC.String(),pname='my_list')
],
pname=('urn:My_URN','My_CLass'))
Look at ZSI.TC to see how to setup the typecode for your MyClass. Note that you need to use that last pname bit in the typecode definition to ensure that the SOAP-Env:Body element is formed properly.
---
That generates a request of the form:
<SOAP-ENV:Body xmlns:ns1="urn:webservices.galileo.com ">
<ns1:My_CLass>
<my_var xsi:type="xsd:string">
etc.
---
How can I generate a request of the form:
<SOAP-ENV:Body>
<My_CLass xmlns="http//myns.com">
<my_var xsi:type="xsd:string">
using TC.Struct? Note, I want the xmlns to appear in the My_CLass line, not the Body line.
Newby Question
Looks like a parameter is missing, not sure how/why this happened.
