Answer 1

Solved my problem using a URIResolver.

class MyURIResolver implements URIResolver {
@Override
public Source resolve(String href, String base) throws TransformerException {
  try {
    ClassLoader cl = this.getClass().getClassLoader();
    java.io.InputStream in = cl.getResourceAsStream("xsl/" + href);
    InputSource xslInputSource = new InputSource(in);
    Document xslDoc = dBuilder.parse(xslInputSource);
    DOMSource xslDomSource = new DOMSource(xslDoc);
    xslDomSource.setSystemId("xsl/" + href);
    return xslDomSource;
 } catch (...

And assigning this with the TransformerFactory

tFactory.setURIResolver(new MyURIResolver());

Answer 2

URIResolver can also be used in a more straightforward way as below:

class XsltURIResolver implements URIResolver {

    @Override
    public Source resolve(String href, String base) throws TransformerException {
        try{
              InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("xslts/" + href);
              return new StreamSource(inputStream);
        }
        catch(Exception ex){
            ex.printStackTrace();
            return null;
        }
    }
}

Use the URIResolver with TransformerFactory as shown below:

TransformerFactory transFact = TransformerFactory.newInstance();
transFact.setURIResolver(new XsltURIResolver());

Or with a lambda expression:

transFact.setURIResolver((href, base) -> {
    final InputStream s = this.getClass().getClassLoader().getResourceAsStream("xslts/" + href);
    return new StreamSource(s);
});

Answer 3

Set your DocumentBuilder object with an EntityResolver.

You'll have to extend EntityResolver class to resolve your external entities (footer.xsl and topbar.xsl).

Answer 4

I had a problem similar to this once with relative paths in the XSLT.

If you can, try to put absolute paths in the XSLT - that should resolve the error.

An absolute path probably isn't preferable for the final version of the XSLT, but it should get you past the maven problem. Perhaps you can have two versions of the XSLT, one with absolute paths for maven and one with relative paths for whatever other tool it's being used with.
