I apologise for my lack of information. What you have given me has helped,
however a new issue has arisen from it.
I did turn off validation as per the other suggestion from my post. This
allowed me to parse the web.xml file, however, I still need to save the
document declaration. When you turn off validation, I was unable to rebuild
DTD reference. Just a note for others who are watching this post.
I am running Java 1.6.0, and I am writing a standalone application. I have
inserted the code snippet as suggested into my SAX parser (using xerces):
public InputSource resolveEntity(String pubid, String sysid) throws
IOException{
if("-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN".equals(pubid)) {
InputStream is =
this.getClass().getClassLoader().getResourceAsStream("/javax/servlet/resourc
es/web-app_2_3.dtd");
return new InputSource(is);
}
return null;
}
I had to add 'this.getClass().' in front of 'getClassLoader()' from your
snippet. If I didn't I would get a compilation error - 'Method
getClassLoader() is undefined'
My parser sets the entity resolver (note: the class WebXmlParser extends
'DefaultHandler'):
public WebXmlParser(StringBuffer tmpIS)
{
System.setProperty("org.xml.sax.driver","org.apache.xerces.parsers.SAXParser
");
try {
// Create SAX 2 parser...
XMLReader xr = XMLReaderFactory.createXMLReader();
xr.setEntityResolver(this);
// Set the ContentHandler...
xr.setContentHandler( this );
try{
xr.parse(new InputSource(new
StringReader(tmpIS.toString())));
}catch(Exception e){
e.printStackTrace();
strError = e.getMessage();
}
}catch ( Exception e )
{
e.printStackTrace();
strError = e.getMessage();
}
}
I now get the following stack trace:

I tried using the 'sysid' from the method to get the 'InputStream', but this
didn't work either. I am presuming it is the 'InputStream' assignment that
is throwing the error, but I am not 100% sure.
Has anyone got any ideas on how to get around this?
Regards,
Andrew

You are a bit sparse on details for how you are doing this and versions, but
assuming that you are using SAX, you need to set and EntityResolver that
does something like (for 5.5):
public ImputSource resolveEntity(String pubid, String sysid) throws
IOException{
if("-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN".equals(pubid)) {
InputStream is =
getClassloader().getResourceAsStream("/javax/servlet/resources/web-app_2_3.d
td");
return new InputSource(is);
}
return null;
}
