AW: [jibx-users] Using jibx-genbinding.jar on a class containing a java.util.HashSet collection

Thu, 15 Sep 2005 09:49:15 -0700

Title: Message
I was messing around with manually _and_ automatically generated binding.xml files - that's the reason for the little confusion.
 
The solution you described works so far. But to be honest I find it a bit disturbing to change my code (even temporarily) to match an insufficent tool. It's espacially not feasible because there will be a fair amount of (more complex) classes. Well, I guess that's the point where any Open Source guru would tell me to have a look into the source :)
 
And that's exactly what I'm going to do tomorrow.
 
Thank you for your quick response and the help, Mocky! I have the slight feeling that this wasn't my last issue on this list ...
 
Alexander

It appears that the binding generator tool doesn't like HashSets. If you change that type to an ArrayList it works fine. As it happens, the binding file it generates for ArrayList collection works unchanged with a HashSet as well, if you just go back into your java code and change it.
 
Since you say you are taking your first steps with JiBX, I just want to make sure you understand that the binding generator only generates a sample binding.xml for you. And that it's the binding compiler that generates the actual code and puts it into your class files. I mention that because you are using the binding generator but seem have what looks like a hand written binding.xml.

Oh, sorry - I missed that. Here it is:
 
<binding>
  <mapping name="SAPDocument" class="de.ava.kas.model.SAPDocument">
    <value name="documentNo" field="documentNo"/>
    <collection field="sapDocumentItems" item-type="de.ava.kas.model.SAPDocumentItem"/>
  </mapping>
  <mapping name="SAPDocumentItem" class="de.ava.kas.model.SAPDocumentItem">
    <value name="documentItemNo" field="documentItemNo"/>
    <value name="documentNo" field="documentNo"/>
  </mapping>
</binding>

Can you show what your binding file looks like?

Hello,

I'm currently taking my first steps with JiBX and already encountered a problem while generating a binding. I hope someone here can give me a hint or two ...

Everything's about two pretty simple POJOs, representing a document and a set of contained items:

public class SAPDocument {
    private String documentNo;
    private HashSet sapDocumentItems = new HashSet();
}

public class SAPDocumentItem {
    private String documentItemNo;
    private String documentNo;
}

The classes have been compiled and now I want to generate the JiBX binding using the generator by calling

java -jar ./jibx-genbinding.jar -v -f .../mappings/binding.xml SAPDocument SAPDocumentItem

Unfortunately this doesn't work - I get the following output:

Running binding generator version 0.2
Building mapping definition for de.ava.kas.model.SAPDocument
creating nested structure definition for java.util.HashSet
Warning: trying to create structure for java.util.HashSet
org.jibx.runtime.JiBXException: No content found for class java.util.HashSet
at org.jibx.binding.BindingGenerator.createStructure(BindingGenerator.java:699)
at org.jibx.binding.BindingGenerator.defineFields(BindingGenerator.java:404)
at org.jibx.binding.BindingGenerator.defineStructure(BindingGenerator.java:621)
at org.jibx.binding.BindingGenerator.createMapping(BindingGenerator.java:736)
at org.jibx.binding.BindingGenerator.generate(BindingGenerator.java:888)
at org.jibx.binding.BindingGenerator.main(BindingGenerator.java:1089)

What does "No content found for class ....." mean? What content is the generator looking for?

Thanks for your help and regards
Alexander
