The general JSF approach would be to use a component that does the iteration
over a list, rather than embedding the iteration in your JSP page. For
example, you might use a table component bound to the entire array:
<h:dataTable ... value="#{savingsBean.accounts}" var="current">
...
<h:column>
<h:inputText ... value="#{current.amount}"/>
</h:column>
...
</h:dataTable>
The table would be bound to an array of account beans, and (as it iterates)
exposes the account bean for the current row in a request attribute named
"current". Inside a column, you can bind components to a property of the
current row's account bean, and the table component deals with all the
looping and indexing for you.
