registerSerializer method

[Roberto Podesta']

Hi to all, I am using Axis-WSIF and I am trying the dynamic invocation with the example from http://www-106.ibm.com/developerworks/webservices/library/ws-wsif2/. I put the command line  java MyDynamicInvoker file_wsdl_location Method_name   I  am getting following exception: Exception in thread "main" java.lang.NoSuchMethodError: javax.wsdl.extensions.ExtensionRegistry.registerSerializer(Ljava/lang/Class;Ljava/lang/Class;Ljavax/wsdl/extensions/ExtensionSerializer;)V         at com.ibm.wsdl.extensions.PopulatedJavaExtensionRegistry.<init>(PopulatedJavaExtensionRegistry.java:29)         at com.ibm.wsif.providers.java.WSIFDynamicProvider_Java.<clinit>(WSIFDynamicProvider_Java.java:37)         at com.ibm.wsif.WSIFDynamicPortFactory.<clinit>(WSIFDynamicPortFactory.java:60)         at MyDynamicInvoker.main(MyDynamicInvoker.java:59) any help? tx Roberto
