i am converting .net web service to java web service in which the code as follows :

String Strresp=dataprocessing.Sav开发者_运维技巧eToDB(argdata,this.Context.Request.UserHostAddress);

how to call User Host Address in java can any one tell me.

From the HttpServletRequest you can use this method

getRemoteHost()

to get the IP address of the user.
