Problem in getting attributes from webservice to servlet when d return type String[]

[Sundhas]

I made a Webservice Operation whose return type is STRING [] Following is the code

@WebMethod(operationName = "authorize") public String [] authorize(@WebParam(name = "Username") String Username) 
{ 
  CAuthorization CA = new CAuthorization(); 
  String [] Result= null; 
  try {
    Result = CA.CheckAuthorization(Username); 
  } catch (SQLException ex) {
    Logger.getLogger(WS_Authentication.class.getName()).log(Level.SEVERE, null, ex); 
  }
  return Result;
}

And then i made a Servlet The code of the servlet thing is :

try { // Call Web Service Operation
  java.lang.String result = null;
  result =  port.authorize(Username);
  out.println("Result = "+result);
} catch (Exception ex) {
  // TODO handle custom exceptions here
}

Problem is in my WEbservice Code in RETURN STATEMENT i have attributes of any table and i want to take these attributes to servlet so that i can see them on my front end but what im getting here is the only the LAST ATTRIBUTE

I WANT TO HAVE ALL THE ATTRIBUTES HERE ; so that i can print them in my front end

HELP!

The authorize-method interface is defined to pass an array of strings (all attributes) back, but you are only assigning a single String (one attribute) for the return value.
"... public String [] authorize(..." --> "..String result = port.authorize(..."

Solution:
"..String[] resultArray = port.authorize(..."

Please be so kind and don't shout in your answer, my ears are still ringing and my eyes are tingling. There is a (B)old-button on the top, please use it.

Hey thanks for the reply
i tried this too what u sugested already but actually it doen't let me it says " That Result is STRING [] and port.authorize (... is SIMPLE string...

any other way to do it in your mind?

what i did i converted STRING [] into string separated with ", " in webservices so that i can get the attributes on servlet... But its not the cool way i want to know how do we get STRING [] in servlet..

Sorry, I don't know much about webservices, but can you return other objects than simple strings?
If yes then you can try with Vector() or ArrayList()

[Sundhas]

Right! Yes we can use ArrayList ( )
Thankyou :)

Hi Sundhas,

Did u solve the problem.
Give you give some example how u finally did it?

Please help!!

Thnx

[Sundhas]

This is the way u can handle Webservice Operation of String Return type

@WebMethod(operationName = "authorize")
public String authorize(@WebParam(name = "Username")
String Username) {

CAuthorization CA = new CAuthorization();
StringBuffer result = new StringBuffer();
try {
if (CA.CheckAuthorization(Username).length > 0) {
result.append(CA.CheckAuthorization(Username)[0]);
for (int i = 1; i < CA.CheckAuthorization(Username).length; i++) {
result.append(",");
result.append(CA.CheckAuthorization(Username)[i]);
}
}
} catch (SQLException ex) {
Logger.getLogger(WS_Authentication.class.getName() ).log(Level.SEVERE, null, ex);
}
//TODO write your implementation code here:
return result.toString();
}

Thanks for reply. Basically i wanted to query database and send the multiple rows to client. Java web service should return multiple rows and columns.

[Sundhas]

Yes.. Previously i was trying to do so but somehow wasnt able to.. So i figured this out.
Sorry can't help more
