Hi Vaibhav, It looks that your typemapping got some typos.
<typeMapping xmlns:ns="http://ttdev.com/ss" qname="ns:>concatRequest" <------------- (ns:>concatRequest without '>' I guess) type="java:com.myproject.simpleservice.ConcatRequest" <---------- (type=... Without "java:com") serializer="org.apache.axis.encoding.ser.BeanSerializerFactory" deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory" encodingStyle="" /> Hope this helps you out.
