NullPointerException when reading the leaves of the XML data

[Peter-Paul Rang]

I'm getting a NullPointerException when reading the leaves of the XML data I can read the XML File correctly, I can walk through the XML structure correctly, I can print it correctly.     String file = "D:/Htb/Dev/message/EE07_xmlbean.xml";     File inputFile = new File(file);     try     {       MCCIMT000100HT02Message message = MCCIMT000100HT02Message.Factory.parse(inputFile);       System.out.println(message.xmlText()); However, when I want to retrieve specific values from the xml file, I get a NullPointerException.           String extension = (String)message.getId().getExtension(); --> java.lang.NullPointerException     at parser.TestMyXMLBean.doAll(TestMyXMLBean.java:42)     at parser.TestMyXMLBean.main(TestMyXMLBean.java:82) Process exited with exit code 0. Any hints and tips are very much appreciated. Thanks, Peter-Paul --       Peter-Paul Rang Development Specialist Business Technology Solutions   Oracle Nederland BV Consulting   Rijnzathe 6 P.O.
