Axis startup error -typeMappingVersion argument must be 1.1 or 1.2

In my server-config.wsdd file, I have <parameter name="typeMappingVersion" value="1.2" />.
I am using Apache Axis version: 1.4 Built on Apr 22, 2006 (06:55:48 PDT) and using websphere 6.0 JDK which is
"J2RE 1.4.2 IBM Windows 32 build cn142sr1w-20041028"
At the start of my web application, it is throwing following error:-
org.apache.axis.ConfigurationException: java.lang.RuntimeException: The -typeMappingVersion argument must be 1.1 or 1.2
java.lang.RuntimeException: The -typeMappingVersion argument must be 1.1 or 1.2
