I've tried to load the included files as resources in the classpath.
Worked fine as long as I was not using the Ant task to run the binding
compiler. In this case the Class loader would be unable to find my
files. Looks like there is some kind of weird interaction between Ant
and the class loaders ...

That's an interesting idea, to search as resources in the classpath.
I=20
think it's too late to include this in 1.0, since I've frozen new=20
features in order to stabilize for the release. Perhaps you can see a=20
way to add this for a post-1.0 release. As a suggestion, the
<include>=20
target doesn't have to be relative to the including file - it's like=20
hrefs in HTML, where if the target doesn't start with a protocol
(such=20
as http:, ftp:, etc.) or '/' it's relative to the origin page. Using
a=20
special custom protocol such as "res://somepackage.someclass" might be
a=20
good way of handling your needs. You'd need to make sure the protocol=20
name didn't conflict with any standard ones, but that shouldn't be a
big=20
problem.
Incidentally, I did take care of detecting the situation you'd=20
originally reported as giving a Runtime exception. It turned out to be
a=20
lot more complex than I'd originally anticipated, so kept me busy for=20
most of the time I was conscious in the 30-hour transit time going=20
Seattle->Los Angeles->Sydney->Wellington.

Thanks for the quick answer, Dennis.
<include> would help me, but as I understand it searches for locations
relative to the inclusing file.
When I have:
Import somePackage.Type
public class SomeObject {
Type type;
}
I have no idea of the location of somePackage relative to my class, I
just assume it is in the classpath.
Would it be possible to have <include> lookup for binding files as
resources ?

Hi Arnaud,
You should be able to do what you want by using <include>:
<binding>
<include path=3D3D"type-binding.xml"/>
<include path=3D3D"status-binding.xml"/>
<mapping name=3D3D"someObj" ...
I'm surprised that your binding:
<binding>
<mapping name=3D3D"someObj" class=3D3D"SomeObject">
<structure field=3D3D"status"/>
<structure field=3D3D"type"/>
</mapping>
</binding>=3D20
got as far as it did (into code generation). This should have been=3D
=3D20
rejected before the code generation phase because there was no
mappin=3D
g=3D20
defined within this binding for the types of the fields.

Hello All,
I've written a little xdoclet to generate the binding files for my
j=3D
=20
ava
=20
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=3D09status;
Type=3D09type;
}
public class Type{
String=3D09name;
}
public class Status{
String=3D09name;
}
Using the following binding works fine:
<?xml version=3D3D'1.0' encoding=3D3D'UTF-8'?>
<binding>
<mapping name=3D3D"status" class=3D3D"Status">
<value name=3D3D"name" field=3D3D"name"/>
</mapping>
<mapping name=3D3D"type" class=3D3D"Type">
<value name=3D3D"name" field=3D3D"name"/>
</mapping>
=3D20
<mapping name=3D3D"someObj" class=3D3D"SomeObject">
<structure field=3D3D"status"/>
<structure field=3D3D"type"/>
</mapping>
</binding>
But if I split the bindings and put the bindings for Type and
Status=3D
=20
in
=20
different files I have the following errors:
With=3D20
<?xml version=3D3D'1.0' encoding=3D3D'UTF-8'?>
<binding>
<mapping name=3D3D"status" class=3D3D"Status">
<value name=3D3D"name" field=3D3D"name"/>
</mapping>
</binding>
<?xml version=3D3D'1.0' encoding=3D3D'UTF-8'?>
<binding>=3D20
<mapping name=3D3D"someObj" class=3D3D"SomeObject">
<structure field=3D3D"status"/>
</mapping>
</binding>
The binding works allright but I have a runtime exception:

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
=3D
=20
of
=20
different classes. What I'd like is a way to generate their mapping
=3D
=20
once
=20
and have it used whenever it is needed.
Thanks for your help,

I think this occurred with Beta 3c when you didn't include the
jibx-run.jar in the classpath set inside the bind task. This should be
corrected with RC0, so that you no longer need to include anything on
the inner classpath except your own classes (one of the many cleanup
items that have gone into RC0).
