How to access to an ArrayList from the JSP

[Johny Harris]

Hiii,

I have the following problem:
I want to show the values of a database in my JSP Page. So far, here are the steps the get the values to my JSP page:

-I created a bean class, where the query to get the values from the database, is executed.
-Then I saved every row of the rows to an ArrayList in form of value objects.
Here is the coding of my bean class:

    ArrayList databaseValue = new ArrayList();

    public void saveToCollection(ResultSet result)  throws SQLException
    {
        while (result.next()) {

             String a = result.getString("loginname");
             String b = result.getString("password");           

            DataValue c = new DataValue(a,b);
            databaseValue.add(c);
        }
    }

Can anyone explain me, how to access my ArrayList in the bean class from the JSP page, to iterate and show the values ?
Could anyone provide me an example?

Kind Regards,
Johny Harris

In the page controller (servlet) for the JSP, create a scoped variable in request scope for the List. For example:

List<Thing> things = fetchListFromDb();
request.setAttribute("things",things);

Then in the JSP it is a simple matter to iterate over the List with the JSTL's <c:forEach>.
