Hi all,
i used Eclipse to create a web service. actually i created a class with the following code:
public class Add2Num {
public int Add2Numbers(int x,int y)
{
return x+y;
}
}
then i tried to generate wsdl file for this class, after i generate the wsdl file, i tried to run it but the following exception appear:
org.apache.axis.InternalException <init>
SEVERE: Exception:
java.lang.Exception: Couldn't find a matching Java operation for WSDD operation "add2Numbers" (2 args)
