Mike Edwards commented on TUSCANY-3559:
---------------------------------------
The WSDL processing uses StaXHelper.createXMLStreamReader( URL url) when
opening a WSDL for reading.
This method creates an XMLStreamReader using a simple InputStream, which
unfortunately means that the original URL for the WSDL, passed in to the
method, is in effect thrown away since the InputStream retains no knowledge of
its originating URL. Thus, when the reference to an external file (the DTD for
example) is encountered, there is no context for the reference and so a simple
reference using a relative URL like "foobar.dtd" cannot be resolved (the
intention in using such relative URLs is effectively to say "use the same
directory as the original file...").
This can be changed quite simply, by instead using a StreamSource instead of an
InputStream - since a StreamSource remembers the original URL and with the
result that the XML Parser can successfully resolve the relative URLs of the
kind shown above.
So, the change to resolve this JIRA is to change the implementation of
StaXHelper.createXMLStreamReader( URL url) (in tuscany-common-xml) to use the
following sequence:
StreamSource scdlSource = new StreamSource( openStream(url),
url.toString() );
return inputFactory.createXMLStreamReader(scdlSource);

> URL: https://issues.apache.org/jira/browse/TUSCANY-3559
> Project: Tuscany
> Issue Type: Improvement
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-2.0-M4
> Reporter: Mike Edwards
> Assignee: Mike Edwards
> Priority: Minor
> Fix For: Java-SCA-2.0-M5
>
>
> Currently, Tuscany cannot process WSDL files that contain references to DTDs.
> This is an unnecessary limitation and prevents the parameterization of WSDL
> files through the use of Entity References, since it is external DTDs that
> provide the means of separately setting the values of Entities that can then
> be referenced within the WSDLs.
> This is needed for the OASIS testcases, where in particular there is the need
> to parameterize Web service endpoint addresses, which vary from one SCA
> runtime to another.
