[jetty-dev] BlazeDs3.x or 4.x are not working as excepted with Jetty 7.x or 8.x server
|
Hi,
I am trying access my Java POJO classes with BlazeDs deployed in Jetty server.
For small requests things are working fine. But for list(ArrayList) of java
object as response drill down to a hang in server. For detail see steps to
reproduce.
*Steps to reproduce*:
Just copying the code I used to simulate problem
*part of MXML*
<mx:RemoteObject id="srv_RO" destination="product_RO"/>
<mx:DataGrid dataProvider="{srv_RO.getProducts.lastResult}" width="100%" height="100%" x="70" />
<mx:Button label="Get" click="srv_RO.getProducts()" />
====================================
*sumit/SumitProduct.java*
package sumit;
public class SumitProduct {
private String name;
private int price;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
}
==============================
*sumit/SumitProductService.java*
package sumit;
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
//import flex.messaging.io.ArrayCollection;
public class SumitProductService {
private static final String[] MASTER_LIST = {"C", "FNM", "FRE", "F", "GOOG",
"AIG", "CSCO", "MSFT", "AAPL", "YHOO", "BSX", "PORT","F", "TNT", "ESP", "RET", "V
BN", "EES"};
public SumitProductService(){}
public List<SumitProduct> getProducts(){
List<SumitProduct> list = new ArrayList<SumitProduct>();
Random r = new Random();
for (String s:MASTER_LIST){
SumitProduct sq = new SumitProduct();
sq.setName(s);
sq.setPrice(r.nextInt(50));
list.add(sq);
}
return list;
}
}
Actual Results:
Hang ... no result
Error is :- [BlazeDS]09:19:26.225 [ERROR] class sun.reflect.GeneratedMethodAccessor7 cannot access its superclass sun.reflect.MethodAccessorImpl
Expected Results:
records set
Workaround (if any):
NO
