The binding generator code can certainly use some improvement. I'm
hoping to get back to this before the end of the year, but no
guarantees. When I do make it back I'll extend it to use some of the
nicer features added to JiBX since the initial version of the generator
(about JiBX Beta 3). I'm thinking of implementing it using ASM for
walking the tree of classes, generating the binding as it goes. I'm also
looking into extending it to use Java 5 generics information as part of
the binding, for people who are using Java 5.

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 ...

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

What does "No content found for class ....." mean?
What content is the generator looking for?
Thanks for your help and regards
Alexander
