I wanted to write a Junit test which tests a class which parses xml files.
From within my application the class works fine and does not throw exception. When I try to run a JUnit test I get the exception

java.lang.ClassCastException: org.apache.xerces.parsers.StandardParserConfiguration

at org.apache.xerces.parsers.DOMParser. (DOMParser.java:109)
at de.wfb.xml.XmlTournament.getDOM(XmlTournament.java:73)
at de.wfb.xml.XmlTournament.getTournament(XmlTournament.java, Compiled Code)
at de.wfb.tests.XMLTest.testGetTournament(XMLTest.java:55)

the relevant lines in class to be tested:

import org.apache.xerces.parsers.DOMParser;
import org.apache.xerces.dom.*;

....


private org.apache.xerces.parsers.DOMParser parser;

.....

parser = new org.apache.xerces.parsers.DOMParser();

The last line throws the exception

Any ideas?

Thanks,

Hans
