Re: NullPointerException when reading the leaves of the XML data

Tue, 28 Jun 2005 02:03:06 -0700

I don't see a problem with this elementFormDefault

a default namespace has been defined in the xml file: xmlns:xsip="urn:hl7-org:v3"
The shema definition specifies:  elementFormDefault="qualified" 
(attributeFormDefault is not specified, and should there for default to "unqualified" )

When I print my xml file with : System.out.println(message.xmlText());
It then shows these settings for elementFormDefault and attributeFormDefault  in the use of the namespace (see below).

I am going to take a wild guess here: is it possible that this is caused by "elementFormDefault", i.e. by the lack of one of those in the Schema?

Subject: NullPointerException when reading the leaves of the XML data


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
