Nevermind. Apparently, I did not set the lax=true on the XmlAnyElement.

 

@XmlAnyElement(lax=true)

OK,

 

I renamed the field and get/set methods, and am still getting the same
problem...?

Subject: Error with XML unmarshalling

 

I have a set of classes (POJOs) that define a workflow Job. The JobDefinition
has a collection of NodeDefinitions that define specific tasks to be done in
the workflow. I am using JAXB-2.1.5 to marshall and unmarshall to/from XML.
Works just fine until I do the unmarshalling from a test XML file...then I am
finding that my collection of Nodes is being populated by JAXB with
ElementNSImpl ?!

 

I can only assume that somehow JAXB is using reflection to get the setNodes()
method to populate this field in my JobDefinition (where Node is
com.ejgallo.worklow.Node):

 

private Collection<NodeDefinition<? extends Node>> nodes = new
ArrayList<NodeDefinition<? extends Node>>();

 

Running this JUnit method:

 

      public void testJobDeserialization() {

            System.out.println("Testing deserialization of Job...");

            InputStream is = null;

            try {

                  is =
this.getClass().getResourceAsStream("test-create.xml");

                  Unmarshaller unmarshaller = context.createUnmarshaller();

                  JobDefinition jobDef =
(JobDefinition)unmarshaller.unmarshal(is);

                  System.out.println("Job name: " + jobDef.getName());

                  Collection<NodeDefinition<? extends Node>> nodes =
jobDef.getNodes();

                  System.out.println("Iterating nodes...");

                  for(NodeDefinition<? extends Node> node : nodes) {

                        System.out.println(node.getName());

                  }

            } catch (JAXBException e) {

                  e.printStackTrace();

                  fail(e.getMessage());

            } finally {

                  if(is!=null) {

                        try {

                              is.close();

                        } catch (IOException e) {}

                  }

            }

      }

 

Gets the following error...

 

java.lang.ClassCastException:
com.sun.org.apache.xerces.internal.dom.ElementNSImpl

 

Do I have to rename my field?
