To be honest, that's a suprise to me as well. Something tells me that
this is wrong .... I will be looking at this through the Jira issue you
raised.
Werner
P.S. Joachim, do you have a view on this ?

I found what the problem was. First I thought, that I only need the classes
in the mapping file, which I want to modify. But after hours of tests, I
found out, that I have to put the whole corresponding class-structure there.
Otherwise all the statements in the mapping file will be ignored. I didn't
know that. The following mapping file works now:
<?xml version="1.0"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"http://castor.org/mapping.dtd";>
<mapping>

Now I reduced my application to only the first few XML tags. Now the
mapping file works, but now I get an additional attribute in the root tag
(ORDERS05) called "valid". How can I avoid this ? I still don't understand
why it works with only a few xml tags.
Here is the result:
<?xml version="1.0" encoding="iso-8859-1"?>
<ORDERS05 valid="true">
<IDOC BLABLA="1"/>
</ORDERS05>
BR,

PS: The original code is also at jira.codehaus.org.

Okay, that makes it more complete to understand what you are trying to
achieve. With regards to your question, yes, this should be possible out
of the box.
My working assumption is that your mapping file is not being picked up,
for whatever reason. The fact that you are seeing one of the info
messages does not necessarily indicate that Castor XML uses a descriptor
as derived from the mapping.
Can you please create a Jira issue and somebody will be having a look ?
When doing so, can you please follow the guidelines at
http://castor.org/how-to-submit-an-xml-bug.html

I was
misunderstanding something, since I'm new to castor. I'll explain what I
want to achieve.
We want to do EDI (especially purchase orders) with several suppliers.
Most
of them have SAP software. So I created a general XML schema definition
(XSD) for this message from which I generated the Java classes. But not
all
of the suppliers will follow correctly this guideline. So for them I
wanted
to use an individual mapping file.
Isn't this possible ?

The fully qualified class name "bestellung.IDOC" is needed here.
Otherwise I
get a MappingException (Class not found...). Since the IDOC class
extends
the SAP_IDOC class, I also tried the following:
<class name="bestellung.SAP_IDOC">
or
<class name="bestellung.IDOC" extends="bestellung.SAP_IDOC">
Both have no effect. The getter and setter methods are in the SAP_IDOC
class.
I'm using castor version 1.1.2.1.
Here is a snippet of the corresponding XML schema. Maybe this helps.
<xs:complexType name="root">
<xs:sequence>
<xs:element name="IDOC" type ="SAP_IDOC"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="SAP_IDOC">
<xs:sequence>
<xs:element name="EDI_DC40" type="header" minOccurs="0"/>
<xs:element name="E1EDK01" type="K01"/>
<xs:element name="E1EDKA1" type="KA1" maxOccurs="3"/>
<xs:element name="E1EDK02" type="K02"/>
<xs:element name="E1EDK35" type="K35" minOccurs="0"/>
<xs:element name="E1EDP01" type="P01" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="BEGIN" type="xs:string" fixed="1"/>
</xs:complexType>

Hi,
very hard to tell, as looking at this, I cannot spot the obvious
error.
What about the fulyl qualified class name of the IDOC class ? If
that#s
wrong, Castor XML will use introspection, which might be what is
happening ?

Werner
PS What Castor version are you using ?

I'm new to castor and I wanted to use a mapping file in order to
modify
my
xml-file in the marshalling process. But the mapping file has no
effect.
Here is the mapping file (Mapping.xml):
<?xml version="1.0" encoding="iso-8859-1"?>
<mapping>
<class name="bestellung.IDOC">
<map-to xml="IDOC"/>
<field name="BEGIN" type="string">
<bind-xml name="BLABLABLA" node="attribute" />
</field>
</class>
</mapping>
Here is the beginning of the original xml file:
<?xml version="1.0" encoding="iso-8859-1"?>
<ORDERS05>
<IDOC BEGIN="1">
<EDI_DC40 SEGMENT="1">
...
Here is my Java code:
...
FileWriter writer = new
FileWriter("Testbestellung_neu.xml");
Marshaller marshaller = new Marshaller(writer);
Mapping mapping = new Mapping();
mapping.loadMapping(new
URL("file:/D:/Temp/XML/Mapping.xml"));
marshaller.setMapping(mapping);
marshaller.setEncoding("iso-8859-1");
marshaller.marshal(orders05);
writer.close();
...
I expected the IDOC segment after the marshalling process like the
following:
<IDOC BLABLABLA="1">
The mapping file is in the classpath. When I call the program, there
is
the
INFO message "Loading mapping descriptors from ...". So the file
will
be
found. And there are no error messages.
What am I doing wrong ?
