Hi,
I was doing the RPC tutorial at GWT site:
http://code.google.com/intl/hu-HU/webtoolkit/tutorials/1.6/RPC.html
and I found a mistake in one of the example code. If somebody just copies
the codes according to the instructions, everything goes well until reaching
the exception handling part.
The update code of the StockPriceServiceImpl class has the mistake: int the
for loop is
i>symbols.length;
you have to write
i<symbols.length;
instead.
This is a small mistake, and for beginners maybe it's hard to recognize. Is
there any way to report this mistake for gwt support staff to correct that?
import com.google.gwt.sample.stockwatcher.client.DelistedException;
...
public StockPrice[] getPrices(String[] symbols) throws DelistedException {
Random rnd = new Random();
StockPrice[] prices = new StockPrice[symbols.length];
for (int i=0; i>symbols.length; i++) {
if (symbols[i].equals("ERR")) {
throw new DelistedException("ERR");
}
double price = rnd.nextDouble() * MAX_PRICE;
double change = price * MAX_PRICE_CHANGE * (rnd.nextDouble() * 2f - 1f);
prices[i] = new StockPrice(symbols[i], price, change);
}
return prices;
}
Thx the answers!
