wsdl/schema import

[Tony Dean <To...@sas.com>]

Hi,

I am importing a schema as follows:

<definitions ...>
   <types>
      <schema ...>
         <import namespace="some URI" schemaLocation="http://www.sas.com/testSchema.xsd/" />
...

This fails with error message: Unable to locate with a locator the schema referenced at '...' relative to document base 'meta-inf/mywsdl.wsdl.

It appears that the Axis2 wsdl processor can only reference schemas relative to the location of the wsdl itself.  If I change the import to:

         <import namespace="some URI" schemaLocation="testSchema.xsd" />

and add testSchema.xsd to meta-inf/ directory in the AAR, it works.


I checked WS-I Basic Profile 1.1 and didn't see any limitation on schemaLocation.  The XML Schema spec does say that this attribute is only a hint.  Is it possible to reference a schema that is not relative to the wsdl?  Is this an Axis2 shortfall or is this the way it works for all webservice stacks?

If you did support such an absolute reference, how would you specify credentials to access the testSchema.xsd if the example site: http://www.sas.com  was secured.  You wouldn't want to specify clear text credentials in the wsdl:
http://username:password@www.sas.com/testSchema.xsd.

FYI: You can't use a file URI either: file:///c:/testSchema.xsd.

I'm thinking that a referenced schema must be relative to the wsdl by design, but I couldn't find any verbage to back up my suspicion.

Anyone else have any thoughts.

Thanks.

An opaque URI is an absolute URI whose scheme-specific part does not begin with a slash character ('/'). Opaque URIs are not subject to further parsing. Some examples of opaque URIs are:

A hierarchical URI is either an absolute URI whose scheme-specific part begins with a slash character, or a relative URI, that is, a URI that does not specify a scheme. Some examples of hierarchical URIs are:
