I followed this tutorial step by step:
http://code.google.com/intl/it-IT/webtoolkit/doc/latest/tutorial/RPC.html
However, I keep getting this error:
23:48:51.203 [ERROR] [stockwatcher] subtype
com.google.gwt.sample.stockwatcher.client.StockPrice is not default
instantiable (it must have a zero-argument constructor or no
constructors at all) and has no custom serializer. (reached via
com.google.gwt.sample.stockwatcher.client.StockPrice[])
Here's my StockPrice.java:
package com.google.gwt.sample.stockwatcher.client;
import java.io.Serializable;
public class StockPrice implements Serializable {
private String symbol;
private double price;
private double change;
public StockPrice(String symbol, double price, double change) {
this.symbol = symbol;
this.price = price;
this.change = change;
}
public String getSymbol() {
return symbol;
}
public void setSymbol(String symbol) {
this.symbol = symbol;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public double getChange() {
return change;
}
public void setChange(double change) {
this.change = change;
}
public double getChangePercent() {
return 100.0 * this.change / this.price;
}
}
Please help me!
