Subject Commons-beanutils indexdProperty error
Date Fri, 10 Oct 2008 05:28:50 GMT
Hi, 

I am very new to the beanutils. 
I am trying to set value to an array list using indexed properties. 

It is throwing the following error 
Exception in thread "main" java.lang.
IndexOutOfBoundsException: Index: 0, Size: 0
    at java.util.ArrayList.rangeCheck(ArrayList.java:572)
    at java.util.ArrayList.set(ArrayList.java:365)
    at org.apache.commons.beanutils.PropertyUtilsBean.setIndexedProperty(PropertyUtilsBean.java:1711)
 
Here is my  code



import java.util.ArrayList;
import java.util.List;

public class Employee {
    
    private String name;
    
    private int id;
    
    private String dept;

    private List<Address> addr=new ArrayList<Address>();
    
    public List<Address> getAddr() {
        return addr;
    }

    public void setAddr(List<Address> addr) {
        this.addr = addr;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getDept() {
        return dept;
    }

    public void setDept(String dept) {
        this.dept = dept;
    }

}



public class Address {


        
    
    private String line;
    
    private String aptno;

    public String getLine() {
        return line;
    }

    public void setLine(String line) {
        this.line = line;
    }

    public String getAptno() {
        return aptno;
    }

    public void setAptno(String aptno) {
        this.aptno = aptno;
    }
    
    
}


public void indexdPropTest(){
        Employee emp=new Employee();
        Address addr=new Address();
        try {
            PropertyUtils.setSimpleProperty(addr, "line","36777" );
            PropertyUtils.setIndexedProperty(emp,"addr",0,addr);
        } catch (IllegalAccessException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        
    }

Can somebody advise me if anything wrong with this? I had tried replacing arraylist with an
array and it was successful. 

Thanks,
D
