Description Nitish Naharas 2001-07-30 20:02:13 UTC
I am using JAXP with Xerces-J 1.4.2.  When using SAXParser with external DTD 
declaration similar to the following xml code snippet, I am getting a null 
pointer exception in xerces-J 1.4.1 as well as 1.4.2. This occurs when the code 
to invoke parsing is executed i.e.
saxParser.parse(inputSource, new InXMLHandler());

The xml snippet is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE InboundRequest [
<!ELEMENT InboundRequest (APIHeader, BusinessObject)>
<!ENTITY % APIHeader SYSTEM "file:///c:/pr/APIHeader.dtd">
<!ENTITY % BusinessObject SYSTEM "file:///c:/pr/Catalog.dtd">

the exception when trying to run it is:
at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1094)
at javax.xml.parsers.SAXParser.parse(SAXParser.java:374)
at testclass.ParsingTest.main(ParsingTest.java:59)
at symantec.tools.debug.Agent.runMain(Native Method)
at symantec.tools.debug.MainThread.run(Unknown Source)

The XML code fully validates using XMLSpy 3.5.  I saw a similar post at 
lists.xml.org but there was no reply to it.  This seems to be a bug.
