Re: Simple Javabean question

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:

   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.

PD:
You can read
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
Chapter 12
Section Expression Language | Variables
for learning how EL works in all cases.

Re: Simple Javabean question

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.
