Can a JSP page retrieve an array off a bean?

[Fritz Largosa]

Can a JSP page retrieve an array off a bean? I have two sample lines below. The first line retrieves the bean saved by the servlet, the second line displays the value of property x. Now if x returned a array, how can I display all values of the array? How can I loop through all array values of x? Thanks for the help, I'm confuse on this one.

<jsp:useBean id="key" type="Package.Object" scope="Application" />

<jsp:getProperty name="key" property="x" />

You'll probably want to look at JSTL for iterating over arrays.

Which version of JSP? Please always include this information when posting a new question.

JSP 2.0

Is there a way to do this in a scriptlet?

[Bear Bibeault]

Of course, but if youare using JSP 2.0 that's like using stone knives and bearskins.

Being sure that the JSTL 1.1 is set up correctly, and that the c library is mapped on the page, it's as easy as (using the naming in your op):

<c:forEach items="${key.x}" var="item">
   [I]body of loop here, which can reference each iteration item as ${item}[/I]
</c:forEach>

Is it possible to iterate through a two dimensional array in a bean? All samples I see pertain to single dimensional arrays or just one string values.

I am needing to convert the code below to JSTL. where array_variable is a two dimensional array.

for(int x =0; ${Bean.array_variable[1][x]} != null; x++){
.....
}

You can nest <c:forEach ../> tags.
