Jibx always gives "Error during validation: null"

I'm really stumped on this incredibly simple mapping. It looks just like one of the examples even. If I comment out the internal structure, it'll run the binding compiler successfully. If I put the internal structure back in, it fails. Note that the internal structure is just defining the XML. This is basically example5 of the JIBX tutorial examples.

<binding>
  <mapping name="RequestTransaction" class="TransactionRequest">
    <value name="version" set-method="setVersion" get-method="getVersion" style="attribute" />
    <structure name="transHeader">
      <value name="requestCount" set-method="setRequestCount" get-method="getRequestCount"/>
    </structure>
  </mapping>
 <binding>

Then I get the following error on the jibx compile:

Error: Error during validation: null; on mapping element at (line 2, col 97, in jibx-binding.xml)

I'm absolutely stumped and out of ideas. Google shows nothing useful.

Solution

  • It's been a while now, but I found it was related to inheritance. I needed to give mappings for everything in the inheritance tree, including interfaces as I recall.

    I ended up creating a wrapper object, which I've found seems to be the easiest way to use JIBX in general. Trying to map a true domain class causes tendrils into every class that class touches and I have to unjar everything so JIBX can find the classes, including 3rd party libs.
