Re: Simple Javabean question

[Nic Werner]

Great, thanks for the pointers. I read the area on EL and that helped, 
but I  am still confused on the 'set' portion. How does the index *and* 
the value get passed to the setter? Using a list, I would need: 
list.set(i,var).

Thanks again for the help, I know this is simple but I'm still trying to 
piece together how these work.

1) If you bean implements List then you could use "myBean[0]" in EL.
public class MyBean implements List
{
        public Object get(int i)
        {
                return getPair(i);
        }
        ...
}
2) Or maybe have a property that implements List "myBean.list[0]".
public class MyBean
{
        public List getList()
        {
                return new List() {
                        public Object get(int i)
                        {
                                return getPair(i);
                        }
                }
                ...
        }
        ...
}

I have a Javabean I've created that has setters and getters to an array:
public String getPair(int idx) {
       return (pair[idx] == null ? "" : pair[idx]);
       }
public void setPair(String[] var) {
       this.pair = var;
       }
My problem is that I don't know how to access the index of the array 
w/JSTL. I can do a regular set and get with just one variable, but 
how do I access this an array index? I've looked all over!

I tried this:
<jsp:useBean id="outlet" class="com.OutletData" scope="session"/>
<c:set var="${sessionScope.outlet.pair[0]}" value="Test"/>
to no avail.
Thanks,
