Hello All,
I've written a little xdoclet to generate the binding files for my java
classes. I generate a xxx.binding.xml for every xxx.java.
But I'm not sure it's the right way to do things with Jibx.
I have the following classes:
public class SomeObject {
Status status;
Type type;
}
public class Type{
String name;
}
public class Status{
String name;
}
Using the following binding works fine:
<?xml version='1.0' encoding='UTF-8'?>
<binding>
<mapping name="status" class="Status">
<value name="name" field="name"/>
</mapping>
<mapping name="type" class="Type">
<value name="name" field="name"/>
</mapping>
<mapping name="someObj" class="SomeObject">
<structure field="status"/>
<structure field="type"/>
</mapping>
</binding>
But if I split the bindings and put the bindings for Type and Status in
different files I have the following errors:
With
<?xml version='1.0' encoding='UTF-8'?>
<binding>
<mapping name="status" class="Status">
<value name="name" field="name"/>
</mapping>
</binding>
<?xml version='1.0' encoding='UTF-8'?>
<binding>
<mapping name="someObj" class="SomeObject">
<structure field="status"/>
</mapping>
</binding>
The binding works allright but I have a runtime exception:

Now if I try to include both type and status in my mapping:
<?xml version='1.0' encoding='UTF-8'?>
<binding>
<mapping name="someObj" class="SomeObject">
<structure field="status"/>
<structure field="type"/>
</mapping>
</binding>
I have a binding error:

So clearly I'm doing something wrong.
Is there a way to separate the binding files for different classes ?
In my case the Status and Type classes would be referenced by a lot of
different classes. What I'd like is a way to generate their mapping once
and have it used whenever it is needed.
Thanks for your help,
