The <structure> is arguably the most important concept in JiBX binding because it allows you to map arbitrary XML to your Java classes without forcing you to create bloated and ugly layers of nested Java objects and classes to match the XML design.
In this case your binding declares that you have an XML element named <transHeader> that will not be present in your Java class.
With some slight fixes to your XML format, your binding works perfectly. I assume the fact that your binding has two <binding> open tags rather than and open and close <binding></binding> is a typo, because you said you got it to work without the structure. Also add <?xml version="1.0"?> at the top of your binding file. Those two XML mods allow the JiBX 1.2 binding compiler to work with the following Java class:
(Note: you didn't provide the Java class this binding is for so I had to reconstruct it from the info you put in the binding file. The obvious side effect of this is that I reconstructed a class that will work with this binding. But the simple fact is that a JiBX binding by design contains all the info you need to know about the class and the XML.)
public class TransactionRequest {
private String version;
private int requestCount;
public void setVersion(String ver) {
version = ver;
}
public String getVersion() {
return version;
}
public void setRequestCount(int count) {
requestCount = count;
}
public int getRequestCount() {
return requestCount;
}
}
compile the class then run the binding compiler with:
>java -jar jibx-bind.jar jibx-binding.xml
To test it I used the following sample.xml:
(Note: you also didn't provide the XML you are trying to map so again I created a sample based on what you did provide)
<?xml version="1.0"?>
<RequestTransaction version="0.1">
<transHeader>
<requestCount>3</requestCount>
</transHeader>
</RequestTransaction>
Running the test uses the following code:
public static void main(String[] argz) {
String fileName = "./sample.xml";
IBindingFactory bfact = null;
IUnmarshallingContext uctx = null;
TransactionRequest sample = null;
try {
bfact = BindingDirectory.getFactory(TransactionRequest.class);
uctx = bfact.createUnmarshallingContext();
InputStream in = new FileInputStream(fileName);
sample = (TransactionRequest)uctx.unmarshalDocument(in, null);
System.out.println(sample.getRequestCount());
System.out.println(sample.getVersion());
}
catch (Exception e) {
e.printStackTrace();
}
}
And it runs successfully.
