axis-admin ant task problem

[Juan Alvarez]

Hello. I'm using axis1.1. My problem is tha the axis ant task don't work properly
This is that I have:
<axis-admin
  url="" href="http://localhost:8080/axis1_1/services/AdminService">http://localhost:8080/axis1_1/services/AdminService"
  xmlfile="${endpoint-stub.wsdd}" />

When I execute this ant task I obtain the next error from ant

BUILD FAILED
  java.lang.NoSuchMethodError: org.apache.axis.client.AdminClient.<init>(Z)V

I enabled the AdminService in web.xml removing comments in
<servlet-mapping>
    <servlet-name>AdminServlet</servlet-name>
    <url-pattern>/servlet/AdminServlet</url-pattern>
  </servlet-mapping>

and put the 'true' value in the enableRemoteAdmin in AdminService in server-config.wsdd as in next

 <service name="AdminService" provider="java:MSG">
  <parameter name="allowedMethods" value="AdminService"/>
  <parameter name="enableRemoteAdmin" value="true"/>
  <parameter name="className" value="org.apache.axis.utils.Admin"/>
  <namespace>http://xml.apache.org/axis/wsdd/</namespace>
 </service>

Note:
The alternative to publish a ws (java -cp $CLASSPATH AdminClient options) does work correctly.

Thanks in advance.
