I am not sure If there is an internal issue or if I am doing something wrong, but I can't get the proper schema for this XML. I appreciate it if someone could let me know how to build it.

Issue:

curl --header "Content-Type: text/xml" --data @"/home/sample_request.xml" "http://127.0.0.1:8080/?wsdl"
<?xml version='1.0' encoding='UTF-8'?>
<soap11env:Envelope xmlns:soap11env="http://schemas.xmlsoap.org/soap/envelope/"><soap11env:Body><soap11env:Fault><faultcode>soap11env:Client.SchemaValidationError</faultcode><faultstring>:1:0:ERROR:SCHEMASV:SCHEMAV_ELEMENT_CONTENT: Element '{http://soap.sforce.com/2005/09/outbound}Notification': This element is not expected.</faultstring><faultactor></faultactor></soap11env:Fault></soap11env:Body></soap11env:Envelope>

My code:

class notifications(ComplexModel):
    __type_name__ = 'notifications'
    
    OrganizationId = Unicode
    ActionId = Unicode
    SessionId = Unicode
    Notification = Unicode

class sObject(ComplexModel):
    __type_name__ = 'sObject'
    __namespace__ = 'urn:sobject.enterprise.soap.sforce.com'

    Id = notifications
    Company_ID__C = notifications
    Company_Size_Text__c = notifications

class SomeService(ServiceBase):
    __tns__ = 'http://soap.sforce.com/2005/09/outbound'

    @rpc(sObject)
    def MyMethod(ctx, mymethodparam):
        print(mymethodparam)


if __name__ == '__main__':
    from spyne.application import Application
    from spyne.protocol.soap import Soap11
    from spyne.server.wsgi import WsgiApplication
    from wsgiref.simple_server import make_server

    logging.basicConfig(level=logging.DEBUG)
    logging.info('listening to http://127.0.0.1:8080')

    application = Application([SomeService],
                          tns=SomeService.__tns__,
                          in_protocol=Soap11(validator='lxml'),
                          out_protocol=Soap11())

    wsgi_application = WsgiApplication(application)
    server = make_server('127.0.0.1', 8080, wsgi_application)
    server.serve_forever()

Hello,

Your code is only vaguely related to your xml request.

The following is not tested but you should get the gist:

class SObjectType(ComplexModel):
    __namespace__ = 'urn:sobject.enterprise.soap.sforce.com'
    Id = Integer64
    Company_ID__C = Integer64
    Company_Size_Text__c = Unicode

class NotificationType(ComplexModel):
    Id = Integer64
    sObject = SObjectType

class SomeService(ServiceBase):
    __tns__ = 'http://soap.sforce.com/2005/09/outbound'

    @rpc(Intege64, Integer64, Unicode, NotificationType)
    def notifications(ctx, OrganizationId, ActionId, SessionId, Notification):
        # ...

Thanks for replying Burak,

I just ran your code suggestion, but it seems it can't find the "notifications" element now. Follow the msg error.

I've tried adding a __type_name__='notifications' in the NotificationType class, but unsuccessfully. This is msg error I've gotten.

I don't know what I am doing wrong here, but it looks like I am running in circles. :(

Sorry I cant fix your code for you. the error messages are quite clear, you don't understand what they say?

I do, but I couldn't find any doc in the repo or example, even on Stack Overflow, that explains how to fix it on Spyne schema side. Especially for the following one.

Element '{http://soap.sforce.com/2005/09/outbound}notifications': No matching global declaration available for the validation root.

I am not asking you to fix my code, but I appreciate it if you could share any idea or something that might help me to get out of this hole.

Thanks,

Element '{http://soap.sforce.com/2005/09/outbound}notifications': No matching global declaration available for the validation root.

this means "I never heard of the tag you are talking about". Is there a schema with tns = "http://soap.sforce.com/2005/09/outbound" ?
is there an object named "notifications" in that schema? The error says there isn't

Thanks a lot for the tip!

I was able to move forward after many attempts, but I am now stuck on this part, which has even very fewer explanations out there.

This is the issue I am getting.

curl --header "Content-Type: text/xml" --data @"/home/sample_request.xml" "http://127.0.0.1:8080/?wsdl"
<?xml version='1.0' encoding='UTF-8'?>

This is the code:

class SObjectType(ComplexModel):
    __namespace__ = 'urn:sobject.enterprise.soap.sforce.com'
    Id = Unicode
    Company_ID__C = Integer64
    Company_Size_Text__c = Unicode

class NotificationType(ComplexModel):
    Id = String
    sObject = SObjectType

class notificationsType(ComplexModel):
    __namespace__ = 'http://soap.sforce.com/2005/09/outbound'
    __type_name__ = 'notifications'
    OrganizationId = Unicode
    ActionId = Unicode
    SessionId = Unicode
    Notification = NotificationType.customize(max_occurs='100')

class SomeService(ServiceBase):

    @rpc(notificationsType)
    def MyMethod(ctx, notificationsType):
        print(notificationsType)

I understand there is a type, Lead, that I need to mention in the SObject class, but it isn't clear how to use it. I've tried to pass a type_name as 'Lead', but It fails. Could you give me some idea how to use it?

Again, your service definition has nothing to do with the document that you are supposed to parse. please try to adopt my version of the service

Hey Burak!
I got another question. What does it mean? Which action should I take to fix it?

<?xml version='1.0' encoding='UTF-8'?>
<soap11env:Envelope xmlns:soap11env="http://schemas.xmlsoap.org/soap/envelope/"><soap11env:Body><soap11env:Fault><faultcode>soap11env:Client.ResourceNotFound</faultcode><faultstring>Requested resource '{http://soap.sforce.com/2005/09/outbound}notifications' not found</faultstring><faultactor></faultactor></soap11env:Fault></soap11env:Body></soap11env:Envelope>

man, are you trolling me? What part of

<faultcode>soap11env:Client.ResourceNotFound</faultcode>
<faultstring>Requested resource '{http://soap.sforce.com/2005/09/outbound}notifications' not found</faultstring>

is difficult to understand?

andrelfran Apr 5, 2022

Not really! Relax buddy! Didn't notice the method had to have the same name as the "Requested resource".

Following the final solution,

NS_C = "urn:sobject.enterprise.soap.sforce.com"

class sObjectType(ComplexModel):
    __namespace__ = NS_C
    Id = Unicode
    Company_ID__C = Integer64
    Company_Size_Text__c = String

class Lead(sObjectType):
    lead_field = Unicode
     
class NotificationType(ComplexModel):
    Id = Unicode
    sObject = sObjectType

NS_B = "http://soap.sforce.com/2005/09/outbound"

class OutboundMessagingService(ServiceBase):
    __namespace__ = NS_B
    @srpc(Unicode, NotificationType, sObjectType, _returns=notificationsResponseReturn)
    def notifications(tctx, Notification, sObject):
        pass ##. Do things here. 

application = Application([OutboundMessagingService], 
                            tns='http://soap.sforce.com/2005/09/outbound',
                            in_protocol=Soap11(),
                            out_protocol=Soap11())

wsgi_application = WsgiApplication(application)

Your lib is pretty handy and works pretty well, by the way, good job man! 💯
The only thing is, some of the "fault" messages are too generic, then the understanding is a little bit confusing. It would be great if there was a "fault" message mapping for each of them with possible missing syntaxes or mistakes.

Thanks for your help,

Yeah sorry, I promise I'm relaxed :) I'm glad it worked for you and thanks for the kind words.

XML Schema, SOAP and WSDL are complicated systems and while it's easy to get basic stuff to work, troubleshooting real-world errors need familiarity with the standards. I do realize I'm talking about maybe half a dozen standards documents spanning thousands of pages but I haven't found any shortcuts and ended up doing my homework.

On the upside, I find the whole XML Schema ecosystem (minus the SOAP bits) pretty well thought-out and the spec text is quite okay to work with.
