XInclude inside jar file

[jackdriver]

hello,

In case of relative path XInclude looks for included file inside current working directory. Let's assume the following file structure:

somedir
|_sometest.xml
test.xml

and test.xml file like this:

<?xml version="1.0"?>
<test xmlns:xi="

http://www.w3.org/2001/XInclude">

<xi:include href="somedir/somefile.xml"/>
</test>

It works fine with JAXB:

JAXBContext jc = JAXBContext.newInstance( "com.xxx.yyy" );
Unmarshaller u = jc.createUnmarshaller();
Object o = u.unmarshal( new File( "test.xml" ));

But the situation is more complicated when our files structure is packed into jar:

test.jar
|_somedir
|_sometest.xml
|_test.xml

JarFile jar = new JarFile("test.jar");
ZipEntry zipEntry = jar.getEntry("test.xml");
InputStream stream = jar.getInputStream(zipEntry);
Object o = u.unmarshal( stream );

In this case the exception is thrown because href is not correctly resolved:

An 'include' failed, and no 'fallback' element was found.

Any hints?

There is a bug in my test.xml. Should be:

<?xml version="1.0"?>
<test xmlns:xi="

http://www.w3.org/2001/XInclude">

<xi:include href="somedir/sometest.xml"/>
</test>

Of course i'm still waiting for hints ...

A jar file is not a tree strucure like directories. AFAIK, it's internally decompressed file by file and they don't keep hierarchical relationship.
