XML DOM processing

[David Brossard]

Hi,

I've written a small application that compare 2 XML documents using the very useful isEqualNode method.
Running my application as is works just fine. When I've 2 equal documents, the isEqualNode returns true.

However, if I deploy my app as an Axis 1.x web service in a Tomcat container, the application within the web service returns false.

That's not all. My application solely relies on the JRE to work (Java 1.5) using the following method to construct a Document from a String:

public static Document loadDocumentFromString(String str, boolean nsAware) throws Exception
{
Document doc = null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(nsAware);
DocumentBuilder parser = factory.newDocumentBuilder();
doc = parser.parse(new InputSource(new StringReader(str)));
return doc;
}

I then compare my 2 EPRs as follows:

matched = incomingDocEpr.isEqualNode(instanceDocEpr);

The previous line threw an InvocationTargetException if I didn't have the latest Xerces implementation in Tomcat's common/endorsed folder (see https://coderanch.com/t/223356/Web-Services/java/InvocationTargetException-axis-WS)

So obivously there's an implementation shipped in the JRE that works and the one in the Xerces implementation (version 2.8) fails. I'm getting kinda lost and confused here... Does anyone have any ideas as to what this may be related to?

BTW, if I send my WS a string with no carriage returns, then the comparison works fine. My application doesn't care about those...
