I propose to add in Configuration class in hibernate :
class Configuration ...
{ ...
public Configuration addPar(File par) throws MappingException
{
log.info("Searching for mapping documents in par: " + par.getName());
JarFile parFile = null;
try
{
try
{
parFile = new JarFile(par);
}
catch (IOException ioe)
{
throw new MappingException("Could not read mapping documents from jar: "
+ par.getName(), ioe);
}
Enumeration jarEntries = parFile.entries();
do
{
if (!jarEntries.hasMoreElements())
break;
ZipEntry ze = (ZipEntry) jarEntries.nextElement();
if (ze.getName().endsWith(".class"))
{
try
{
String classname = ze.getName();
classname = classname.substring(0, classname.length() - 6)
.replace('/', '.');
log.info("Found class in jar: " + classname);
addClass(Class.forName(classname));
}
catch (Exception e)
{
throw new MappingException(
"Could not read mapping class from par: " + par.getName(), e);
}
}
} while (true);
}
finally
{
try
{
if (parFile != null)
parFile.close();
}
catch (IOException ioe)
{
log.error("could not close jar", ioe);
}
}
return this;
}
...
}
And, it must necessary to update the DTD and the parser. If I found the time, I will propose a patch.
