Attempting to set up PEAR::SOAP server to be accessed using Microsoft Soap
Toolkit 3 extensions - I'm testing by writing VBScript in ASP pages...
Using the example server for the PEAR::SOAP (I have not included code
framents from these, let me know if they are needed, I assume if you know
PHP::SOAP you have access to these), I am able to access the server using
the example PHP client, but, in some cases, have had problems when using
the MSSOAP toolkit client.
For instance, for the 'divide' method of the example PHP server works when ,
when accessed by the PHP client, but with the MSSOAP client, complains it
exected type 'int' for the input parameters, rather than type 'string'. For
the examples where the expected type *is* string, it is possible to
exchange data without problems.
Within the SOAP_Example_Server class definition, the input parameters are
indeed set as 'int' for the 'divide' function.
A quick comparison of the XML message send by the PHP client and MSSOAP
client showed that the PHP client did indeed specify the type, whereas the
MSSOAPclient did not.
While it seems to be possible to use the lower level API in MSSOAP to
consruct the message manually, that is not desirable as it removes me from
the simplicty that is what writing a SOAP client is supposed to be about.
I'm a systems administrator, so the simpler the better ;)
Is there a way, at the server end, that it is possible to force the
interpretation on a message part to be a particular type, as from my
experience above, it seems the server is assuming the type to be a string
unless it is expicitly set by the client?
