xi:include in xml file within jar file does not work in WildFly
Here's the scenario:
I bundled several .xml (somewhat of a configuration) files needed for my application to run in an .jar file. The jar file has the following structure:
settings-1.0.0.jar
˪ resources/
˪ 1.xml
˪ 2.xml
˪ 3.xml
˪ META-INF/
˪ MANIFEST.MF
1.xml has the following content:
<?xml version="1.0" encoding="UTF-8"?>
<document xmlns:xi="http://www.w3.org/2001/XInclude">
<!-- Include 2 -->
<xi:include
href="resource:resources/2.xml" />
<!-- Include 3 -->
<xi:include
href="resource:resources/3.xml" />
<!--
<map>
</map>
-->
</document>
based on this article. When trying to access these includes (after successfully deploying my application) I get the following error:
Caused by: org.xml.sax.SAXParseException; lineNumber: 5; columnNumber: 43; An 'include' failed, and no 'fallback' element was found.

I tried(&error'd) all thinkable options. What's the right combination for xi:include 'ing an .xml file in a jar -file installed as WildFly module?
Edit: Here's how the xmlfile is loaded:
private void loadBackendMapping() {
try {
BackendMappingParser parser = new BackendMappingParser();
InputStream in = ResourceLoaderHelper.getResourceAsStream(BACKEND_MAPPING_RESOURCE);
if (in == null) {
throw new FileNotFoundException();
}
try {
parser.parse(in);
} finally {
try {
in.close();
} catch (IOException e) {
log.warn("Failed to close " + BACKEND_MAPPING_RESOURCE, e);
}
}
backendMapping = parser.getMapping();
if (log.isDebugEnabled()) {
log.debug(BACKEND_MAPPING_RESOURCE + " successfully loaded!");
}
} catch (FileNotFoundException e) {
log.warn(""" + BACKEND_MAPPING_RESOURCE + "" not found!");
backendMapping = new BackendMapping();
} catch (Exception e) {
throw new CenterwareSystemException("Failed to parse " + BACKEND_MAPPING_RESOURCE, e);
}
}
BACKEND_MAPPING_RESOURCE contains the filename ( 1.xml ).
It depends on your XML parser.
As per your exception it seems you use SAX.
Try this article: https://www.ibm.com/developerworks/library/x-tipentres/
The above document uses the SAX API 's EntityResolver interface for locating resources in an XML document.
Remove the "resource:" prefix from your URLs, as this seems to be a JBoss specific protocol.
Also emit the "resource/" path, as 1.xml, 2.xml and 3.xml all reside in the same folder and you usually specify relative path (from 1 to 2 and from 1 to 3).
Try the following:
<?xml version="1.0" encoding="UTF-8"?>
<document xmlns:xi="http://www.w3.org/2001/XInclude">
<!-- Include 2 -->
<xi:include href="2.xml" />
<!-- Include 3 -->
<xi:include href="3.xml" />
<!--
<map>
</map>
-->
</document>
