XOM testing at xubuntu are fail

I tried to use XOM at my easy project for generate xml files.

I follow instructions Installing XOM.

I added jar to my project it works perfect. But I can't run their easy test example:

To check your download you can run one of the sample programs found in the xom-samples.jar file. For instance, nu.xom.samples.PrettyPrinter class formats an XML document by inserting and removing white space around element boundaries. In Java 1.4 and later you can run it from the command line like this:

$ java -classpath xom-samples.jar:xom-1.1.jar nu.xom.samples.PrettyPrinter filename.xml

here is how it looks:

Due to an IOException, the parser could not check filename.xml

Solution:

Create items.xml at same directory:

<?xml version="1.0" encoding="ISO-8859-1"?>
<items xml:base="file:///home/nazar/Downloads/XOM/items.xml">
    <item>
        <product>
            <description>Ink Jet Refill Kit</description>
            <price>29.95</price>
        </product>
        <quantity>8</quantity>
    </item>
    <item>
        <product>
            <description>4-port Mini Hub</description>
            <price>19.95</price>
        </product>
        <quantity>4</quantity>
    </item>
</items>

Why this exactly happen?

Any suggestions?

filename.xml simply doesn't exist in this directory. Replace by the path of another XML file. The IOException tells you there was an error in the input. It's because Java can't find the file
