Hello, I have a problem with xml document validation.
Here is a source code, the xml document to be validated and the error message. This source code is running without any error with the xerces of JBuilder6. But failing to run on the standard xerces jar files from www.apache.org. Fact-1: xerces coming with JBuilder6 : 1.767 bytes xerces 1.4.3 from Apache : 769 bytes xerces 2.0.0. from Apache : 769 bytes xerces 2.0.1 from Apache : 769 bytes conclusion: JBuilder's xerces includes something extra. Fact-2: I have 3 different examples, 1 from www.wrox.com, for the book: XML Schema, 2 examples from http://java.sun.com. All of them are running on JBuilder's xerces, but all of them giving error in apache's xerces: 1.4.3, 2.0.0, 2.1.0. Question: How can I run the same xml schema validation programs on the standard xerces from apache? please look at the example below: --------------------------------------------------------- 1. CODE 2. ERROR 3. XML DOCUMENT 1. CODE ---------------------------------------------------------- parser.setFeature( "http://xml.org/sax/features/validation";, true); // "instance" is the String variable for the address of the xml document. // parser.parse(instance); --> THIS MUST BE A BUG! This line is causing problem! FileInputStream fis = new FileInputStream(instance); parser.parse(new InputSource(fis)); NOT: Please find complete source code at the end. 2.
