http://nagoya.apache.org/bugzilla/show_bug.cgi?id=3945 NPE when using an InputSource for a document with an external parsed entity Summary: NPE when using an InputSource for a document with an external parsed entity Product: Xerces-J Version: 1.4.3 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: Core AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] If I create a parser (SAX or DOM) and then try an parse an InputSource I create directly from a FileReader, I get a NullPointerException if the xml contained by the reader has any external parsed entities defined in it. If the xml has no external entities (internal ok), the parse succeeds, and if I parse using a String systemId instead of a InputSource, the parse also succeeds. If there is some precondition to using InputSources (like setting the systemId...?) then a more helpful error message would be a good idea. e.g. foo.xml: <?xml version="1.0"?> <!DOCTYPE foo [ <!ENTITY baz SYSTEM "baz.xml"> ]> <foo/> baz.xml: <baz/> foo.java: import org.xml.sax.*; import org.xml.sax.helpers.*; import java.io.*; public class foo { public static void main (String[] args) { try { String filename = args[0]; XMLReader reader = XMLReaderFactory.createXMLReader ("org.apache.xerces.parsers.SAXParser"); InputSource src = new InputSource(new BufferedReader (new FileReader(filename))); // reader.parse(filename); //this works reader.parse(src); // This NPE's } catch (Exception ex) { System.out.println("Unexpected exception: " + ex); ex.printStackTrace(); } } } javac -classpath .;xerces.jar foo.java java -classpath .;xerces.jar foo foo.xml --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
