To generate the java code, server side, from the wsdl, the better way is to use the tool apache-cxf ( http://cxf.apache.org/download.html ) . Unzip this tool and go to the folder bin.

In this folder you will find the script wsdl2java.sh, use it for the generation.

example :

aboufahj@yaka:~/Applications/apache-cxf-2.7.6/bin$ ./wsdl2java -p net.ihe.gazelle.xdstar.validator.ws -all -d /home/aboufahj/tmp/xdsr2/ /home/aboufahj/Documents/workspace/ITI/wsdl/XCARespondingGatewayQuery.wsdl

After generating, there still missing annotations in the generated interfaces, add : 

@BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)
@Addressing(enabled=true)

and on the generated implementation class, you have to add :

@Stateless
