Hello Keith
Your work-around loaded both mapping files correctly. But the work-around is no
solution for me because the common-binding.xml is not used with every binding
file. So I tried to find another solution and I think that I've found the fault
that I've made.
The loading of the mapping.dtd is the problem. Because I defined it as SYSTEM
(<!DOCTYPE mapping SYSTEM "mapping.dtd">) Castor tries to load it from the
install directory of eclipse. Castor throws a MappingException in the Method
loadMappingInternal() but the Exception is ignored in the Method unmarshalled()
in the Mapping class.
public void unmarshalled (Object object) {
if (object instanceof Include) {
Include include = (Include) object;
try {
loadMappingInternal( include.getHref() );
}
catch ( Exception except ) {
//-- ignore error, it'll get reported
//-- later when we re-process the
//-- includes of the parent Mapping in
//-- loadMappingInternal
}
}
}
Castor tries to load the includes in the parent Mapping class. But the method
_state.processed() returns true for the include elements because the state was
set before the iteration over the includes. So the error wasn't reported and
the include file wasn't correctly loaded.
// Load all the included mapping by reference
//-- note: this is just for processing any
//-- includes which may have previously failed
//-- using the IncludeListener...and to
//-- report any potential errors.
Enumeration includes = loaded.enumerateInclude();
while ( includes.hasMoreElements() ) {
Include include = (Include) includes.nextElement();
if (!_state.processed( include.getHref() )) {
try {
loadMappingInternal( include.getHref() );
}
catch ( Exception except ) {
throw new MappingException( except );
}
}
}
I've changed the definition of the DOCTYPE to
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"http://castor.org/mapping.dtd";>
And that solved the problem with the loading of the mapping file.
Thanks a lot for your help.
Greetings Christian

Christian,
I'm not sure what the problem would be in resolving the included mapping,
however you could try the following as a work-around:
Mapping mapping = new Mapping();
mapping.loadMapping(commonMappingURL);
mapping.loadMapping(mashalBindingURL);
If I recall correctly, that should load both mapping files.
