after a litztle bit of debugging, I've traced this exception to the following code
fragementin Types.java:
public static Class typeFromName( ClassLoader loader, String typeName )
throws ClassNotFoundException
{
for ( int i = 0 ; i < _typeInfos.length ; ++i ) {
if ( typeName.equals( _typeInfos[ i ].shortName ) )
return ( _typeInfos[ i ].primitive != null ? _typeInfos[ i ].primitive
:
_typeInfos[ i ].javaType );
}
if ( loader != null )
return loader.loadClass( typeName );
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
else
return Class.forName( typeName );
The exception occurs at the line marked with '�'. Any idea why ?
'org.exolab.castor.types.Duration' is on the classpath, afai can tell.

Tomasz,
Thank you for the patch information. Did the SQLTypeConvertors above work for your
situation?
