Error when calling the method in service

Question

Now I know how to give certain parameters to the service when invoking the call asked in the previous thread, but I got errors when I try to run it:
namespace mismatch require http://myservices.supermarket found none
java.net.MalformedURLException
     at java.net.URL.<init>(Unknown Source)
     at java.net.URL.<init>(Unknown Source)

     at supermarket.myservices.SupermarketClient.run(SupermarketClient.java:63)
     at supermarket.myservices.SupermarketClient.main(SupermarketClient.java:219)
And below is my client program's code:
public void invokeWebService(){
          try{
               this.isID = new String("selected");
               this.isBrand = new String("selected");
               this.isName = new String("selected");
               this.isWeight = new String("selected");
               this.isPrice = new String("selected");
               this.isSpecialPrice = new String("selected");
               this.isMemberPrice = new String("selected");
               this.isType = new String("seletced");
               //service address
               String endpoint = "http://localhost:8080/axis2/services/Supermarket";
               //initialize web service call
               Service  service = new Service();
               Call call = (Call) service.createCall();
               Object[] params = new Object[]{isID, isBrand, isName, isWeight, isPrice, isSpecialPrice, isMemberPrice, isType};
                 //set web service address
               call.setTargetEndpointAddress(new java.net.URL(endpoint) );
               //set operation name
               call.setOperationName(new QName("execute"));
               //call the service and get the result ret
               String ret = (String)call.invoke(params);
               initialReader(ret);
          catch (Exception e)
               System.err.println(e.toString());
     }What's wrong with it? I really don't have any idea on it......
