Axis deserialization problem (org.xml.sax.SAXException: Bad types)

[babaxter1]

Linking again axis1.4 libs, we get the following error, when trying to
access one of our webservices.

org.apache.axis.AxisFault
org.xml.sax.SAXException: Bad types class a.b.c.d.e.f.g.Class_X ->
class a.b.c.d.e.f.g.Class_Y)

I don't see an issue in the defined type mapping in server-config.wsdd:

<typeMapping
xmlns:ns="urn:kba"
qname="ns:Class_X"
type="java:a.b.c.d.e.f.g.Class_X"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"

deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>

Any hints are welcome.
