 * [heikki] XML binding:
  In the ebRIM branch, and in the Nordic Security code (not public yet), JiBX is used for Java <--> XML binding. It is highly useful to have such a binding, as it can be invoked automatically on Web Service communications and leads to a much cleaner dealing with objects in Java than when DOM/JDOM is used. One disadvantage of JiBX is that this binding needs to be written manually, which is a bit of a pain in the neck. Another disadvantage is that it is not a Java standard. JAXB on the other hand *is* the standard and comes with a binding-generator that takes a schema and produces the bound Java classes. 

However, I've tried running it on the ISO19139 schema and it does not work :

 {{{

~/jaxb-ri-20110115/bin$ xjc -p testpackagename ~/source/ogc/ogc-schemas/trunk/iso/19139/20070417/schema/src/main/resources/iso/19139/20070417/gmd/gmd.xsd

The result is :

parsing a schema...
[ERROR] Property "Rows" is already defined. Use <jaxb:property> to resolve this conflict.
 line 648 of file:
~/source/ogc/ogc-schemas/trunk/iso/19139/20070417/schema/src/main/resources/gml/3.2.1/geometryPrimitives.xsd

~/source/ogc/ogc-schemas/trunk/iso/19139/20070417/schema/src/main/resources/gml/3.2.1/geometryPrimitives.xsd

Failed to parse a schema.

 }}}

This is because of peculiarities in the schemas that we cannot control. I have asked !users@ogc.java.net if it is possible to do this at all, but I'd be surprised.

Question remains: if we cannot use JAXB to generate a binding for ISO19139, is it still desired to use JAXB for situations where we *can* use it, instead of using JiBX ?
