Help! MBeanCreationException: Unable to create bean...missing create method

Question

I am trying to configure an authentication provider with ant using the wlconfig task. This has been working fine until recently and I have no idea what could be wrong. The ant script has not changed and I'm not sure what information to post to be more useful. Hopefully someone has had this problem or can point me in the right direction.
Below is the target I'm trying to run. I fails with the following exception. I am able to configure the provider manually through the console, however, but this is not an option for our deployments:
Caused by: weblogic.management.MBeanCreationException: Unable to create new bean of type com.xxx.MyAuthenticator for myDomain:Name=myDomain,Type=Domain:missing create method
Caused by: java.lang.NoSuchMethodException: MyAuthenticator(java.lang.String,)
     <target name="configure-auth-provider">
          <echo message="Configuring Security Auth Provider..."/>
          <taskdef name="wlconfig" classname="weblogic.ant.taskdefs.management.WLConfig" classpath="${weblogic.jar}"/>
          <wlconfig url="t3://${weblogic.host}:${weblogic.listen.port}" username="${weblogic.username}" password="${weblogic.password}">
               <create type="com.xxx.MyAuthenticator" domain="Security" name="MyAuthenticator" property="MyAuthenticator">
                    <set attribute="ControlFlag" value="OPTIONAL"/>
               </create>
               <query type="weblogic.management.security.Realm" domain="Security" name="MyCustomRealm">
                    <set attribute="AuthenticationProviders" value="MyAuthenticator"/>
               </query>
          </wlconfig>
          <echo message="Security Auth Provider configured Successfully."/>
     </target>

Hi Balaji,
LSMW using IDOC is similar to using flat file method. Here you are getting data from IDOC container and mapping data with Idoc segments insted of flatfile column.
Hope this is what you are looking for. If helpful then don’t forget to reward me for that
