When I call a ejb3 method and this return a big collection (> 1000 items), in the moment which of pass the collection over net, some elements have values changes (sometimes :-( ). Very strange. See:
@Stateless
@Remote(MakeListOfBigDecimal.class)
public class MakeListOfBigDecimalBean {
public List makeList(){
List list = new ArrayList(12020);
for (int i = 0; i < 12020; i++) {
BigDecimal anyValue = null;
if (i % 2 == 0){
anyValue = new BigDecimal("1.25");
}else{
anyValue = new BigDecimal("2.13");
}
anyValue = anyValue.setScale(2, BigDecimal.ROUND_HALF_EVEN);
list.add(anyValue);
}
BigDecimal sum = BigDecimal.ZERO;
sum = sum.setScale(2, BigDecimal.ROUND_HALF_EVEN);
for (Iterator iter = list.iterator(); iter.hasNext();) {
BigDecimal bd = (BigDecimal) iter.next();
sum = sum.add(bd);
}
System.out.println("SUM INSIDE MakeListOfBigDecimalBean: " + sum);
return list;
}
}
@Stateless
@Remote(ReadAndSumBigDecimalList.class)
public class ReadAndSumBigDecimalListBean {
@EJB
private MakeListOfBigDecimal makeListOfBigDecimal;
public void doSumAfterRemoteCall(){
List list = makeListOfBigDecimal.makeList();
BigDecimal sum = BigDecimal.ZERO;
sum = sum.setScale(2, BigDecimal.ROUND_HALF_EVEN);
for (Iterator iter = list.iterator(); iter.hasNext();) {
BigDecimal bd = (BigDecimal) iter.next();
sum = sum.add(bd);
}
System.out.println("SUM INSIDE ReadAndSumBigDecimalListBean: " + sum);
}
}
The output after 4 calls:
SUM INSIDE MakeListOfBigDecimalBean: 20313.80
SUM INSIDE ReadAndSumBigDecimalListBean: 20312.04
SUM INSIDE MakeListOfBigDecimalBean: 20313.80
SUM INSIDE ReadAndSumBigDecimalListBean: 20313.80
SUM INSIDE MakeListOfBigDecimalBean: 20313.80
SUM INSIDE ReadAndSumBigDecimalListBean: 20312.04
SUM INSIDE MakeListOfBigDecimalBean: 20313.80
SUM INSIDE ReadAndSumBigDecimalListBean: 20314.68
If I change @Remote and put @Local, all works fine..
My JBoss version is - 4.0.4.CR2
