Getting error "No element type is defined for message NewOperationRequest"

Question

i'm reating WSDL file in eclipse from new -> other -> wsdl. I want to use "type" instead of "elements". but when i creating stub of the wsdl getting below error:

$AXIS2_HOME/bin/wsdl2java.sh -uri MRManagerService.wsdl -p org.apache.axis2.axis2userguide -d adb -s
