wsdl2erlang client generation: Namespace not found

[sveinfid]

I'm trying to generate a client using wsdl2erlang, and I'm seeing the following error "Namespace not found".

Any ideas what could be wrong here?

The namespace in question is without a http:// prefix, could that be the issue?

2> soap:wsdl2erlang("http://my_host/path?wsdl").
What must be generated?
1: client
2: server
3: both
Select a number: 1

Do you want to generate test stubs/skeletons?
1: no
2: yes, client only
3: yes, server only
4: yes, client and server
Select a number: 2

Which http client must be used?
1: ibrowse
2: inets
Select a number: 2

(Probably this response comes too late to help you, but in case other people run into this problem)

If the location of the include file starts with "http://" or "https://", soap:wsdl2erlang will try to retrieve it from the url. If not, it will try to get it from disk.

You can modify this behavior by providing an erlsom_option (erlsom is the parser that is used to parse the WSDL). Erlsom offers various options to find included files, for example you can pass a list of directories or your own function to locate the XSD given the namespace.

Hi @sveinfid, did you success to resolve the bug of "Namespace not found.." ? I have the same error.

@willemdj can you explain how to pass option to erlsom to fix this bug ?

Thanks

Something like:

soap:wsdl2erlang("http://my_host/path?wsdl", [{erlsom_options, [{include_fun, IncludeFun}]]).

where IncludeFun is a function that finds the files that are included or imported in the XSD. It should be a function that takes 4 arguments:

• Namespace (from the XSD). This is a string or 'undefined'
• SchemaLocation (from the XSD). This is a string or 'undefined'
• Include_files. This is the value of the ‘include_files’ option if this option was passed to compile_xsd(); [] otherwise.
• Include_dirs. This is the value of the ‘include_dirs’ option if this option was passed to compile_xsd(); 'undefined' otherwise.

Include_fun should return {XSD, Prefix}, where XSD is a XSD = string(), Prefix = string or 'undefined' - if the value is undefined, ‘P’ will be used.

There are other erlsom_options that you might use, for example you can pass the name of a directory where the files are located. See https://github.com/willemdj/erlsom/blob/master/doc/reference.md#compile_xsd
