What JAR files are required to run dom\Counter.java provided in the Apache Xerces package?

You can follow this toturial to find out what JAR files are required to run dom\Counter.java provided in the Apache Xerces package.

1. Create an XML file in the \fyicenter\xerces-2_11_0\ folder:

\fyicenter\xerces-2_11_0\samples>type User.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- Copyright (c) 2017 FYIcenter.com -->
<User>
    <ID>101</ID>
    <BirthDate>1970-01-01+00:01</BirthDate>
    <Name>Frank Y. Ivy</Name>
    <Sex>  Male</Sex>
</User>

2. Compile the dom\Counter.java and run it. Execution fails with missing dom.wrappers.Xerces class:

\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\javac 
   dom\Counter.java

\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\java 
   -cp . dom.Counter User.xml
error: Unable to instantiate parser (dom.wrappers.Xerces)

3. Run it again with xercesSamples.jar. Execution fails with missing org.apache.xerces.parsers.DOMParser class:

\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\java 
   -cp .;..\xercesSamples.jar dom.Counter User.xml

4. Run it again with xercesImpl.jar added. Execution fails with missing org.w3c.dom.ElementTraversal class:

\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\java 
   -cp .;..\xercesSamples.jar;..\xercesImpl.jar dom.Counter User.xml

   at dom.Counter.main(Counter.java:447)
Caused by: java.lang.ClassNotFoundException: org.w3c.dom.ElementTraversal

4. Run it again with xml-apis.jar added. Execution goes well now.

\fyicenter\xerces-2_11_0\samples>\fyicenter\jdk-1.8.0\bin\java 
   -cp .;..\xercesSamples.jar;..\xercesImpl.jar;..\xml-apis.jar 
   dom.Counter User.xml

User.xml: 162;9;0 ms (5 elems, 0 attrs, 0 spaces, 58 chars)

3 JAR files are needed to run dom.Counter: xercesSamples.jar, xercesImpl.jar, and xml-apis.jar.
