Saxon

How do you supply details of the configuration file to Saxon? The first thing to establish is that Saxon knows the base URI.

Although JAR file URIs are non-standard, if we have a base URI that's a file within a JAR, we should be able in principle to use it to locate other files in the same JAR using relative URIs; the most likely explanation for the observed effect is that we don't know the base URI.

I'm getting the file from the resources folder as a stream:

InputStream saxonConfig = getClass().getClassLoader().getResourceAsStream("config-saxon.xml");
this.saxon = new Processor(new StreamSource(saxonConfig));

Is the base URI getting lost in this process?

I'm wondering if I might have better results by supplying an instance of the Configuration class instead of the file. But I've not looked into that.

Well, there's no systemId property on the StreamSource, so Saxon doesn't have a base URI to work with.

And it's not easy to suggest what you should supply. You could try "classpath:config-saxon.xml" - I've no idea if that would work.

Perfect, thanks!

A method that works:

ClassLoader cl = getClass().getClassLoader();
String systemID = "config-saxon.xml";
InputStream saxonConfig = cl.getResourceAsStream(systemID);
URL url = cl.getResource(systemID);
Source source = new StreamSource(saxonConfig);
source.setSystemId(url.toExternalForm());
this.saxon = new Processor(source);

Great, good to know.

As a matter of interest, what does the result of url.toExternalForm() look like?

When I run the application within NetBeans the value is

file:/C:/SVN/software/Atlas/BITS2MARC/MARC_creator/target/classes/config-saxon.xml

When I run the application as a jar the value is

jar:file:/C:/mjd/data-samples/scripts/BITS2MARC/MARC_creator.jar!/config-saxon.xml

(Maven has placed the config-saxon.xml file at the top level of the jar when building the jar.)
