Hi Sebasiten,
This type of error happens even when I define a very simple api, e.g. output the whirr version.

The following is the response object:

public class LaunchClusterResponse extends BaseResponse {
@SerializedName(ApiConstants.IS_ASYNC) @Param(description = "true if api is asynchronous") 
   private Boolean isAsync;
   @SerializedName("output") @Param(description = "whirr output")
   private String output;

   public LaunchClusterResponse(){

   }
   public void setAsync(Boolean isAsync) {
       this.isAsync = isAsync;
   }

   public boolean getAsync() {
       return isAsync;
   }
   public void setOutPut(String output) {
       this.output = output;
   }
    public String getOutput(){
       return output;
   }

}


The following is the execute method of the command object.

public void execute()  {
       LaunchClusterResponse response = new LaunchClusterResponse();
       response.setObjectName("launchCluster");
       response.setResponseName(getCommandName());

       String cmdToExec;
       cmdToExec = "whirr version ";
       try {
          Process proc = Runtime.getRuntime().exec(cmdToExec);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream())); BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream())); 

          String stdout = "",stderr = "",s;
          while ((s = stdInput.readLine()) != null) {
               stdout=stdout+s;
          }
          while ((s = stdInput.readLine()) != null) {
               stderr=stderr+s;
          }
          output = stdout+stderr;
       } catch (IOException ex) {
Logger.getLogger(LaunchClusterCmd.class.getName()).log(Level.SEVERE, null, ex); 
       }

       response.setOutPut(output);
       this.setResponseObject(response);
   }


Thanks!


So what do you get in cloudmonkey, can you send the json ?


Sebastien, below  is what I get in CloudMonkey:

Hi folks,
I am adding an api (launch cluster) to CloudStack and using CloudMonkey to test the api.
From the CloudMonkey log file I can see that the request was executed on the server side and return correct response, however, CloudMonkey was forced to quit because the following error:

Meng, this actually might be an issue with your response object in
java, make sure that it is properly defined.

You can also send us the json that's returned via cloudmonkey



Could someone give me  a pointer why this is happening?


Thanks!

Cheers,
Meng
