Hi,

it works for me (in a win cmd shell). First I set the CLASSPATH to
contain xerces.jar and another jar containing the w3c classes, and then
i import the DOMParser 

C:\jython>set CLASSPATH=c:/workspace/external/lib/xerces.jar

C:\jython>set CLASSPATH=%CLASSPATH%;c:/workspace/external/lib
/xml-apis.jar

C:\jython>jython.bat
Jython 2.1 on java1.3.1_06 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> from org.w3c.dom import CharacterData
>>> from org.apache.xerces.parsers import DOMParser
>>> DOMParser
<jclass org.apache.xerces.parsers.DOMParser at 3308600>
>>>

by the way:

>>> import org.w3c.dom.*
Traceback (innermost last):
  (no code object) at line 0
  File "<console>", line 1
        import org.w3c.dom.*
                           ^

Hope to have helped - best wishes,
