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
