Need help on shopping cart javaBean code*

Tue, 28 Jul 2009 17:31:23 -0700

Compiling the following code outputs the error that the javaBean curItem does not exist. However, my other code depends on a javaBean curItem. I don't understand why I cannot update the quantity property of a specific object (curItem) in the arrayList lineitems if I am declaring curItem to be an object inside lineitems using the var attribute. Please clarify and perhaps help update the quantity property in an object in lineitems using a curItem javabean. Thanks!
