page 446 target value as array?

[Ner min]

hi in book they say that c:set var is for bean and maps and that it have to take string. Thats ok.
but they say to that c:set target os for lists and arrays???

so in my jsp i made
<%
String[] language={"asp","jsp","php"};
%>
and then
<c:set target="${language}" property="0" value="aspNet"/>
but it does not work. Anyone knows how to access array index via c:set target?

Hi Ner,


<c:set var="var" value="asp" />
is for setting attributes.

<c:set target="${myBean}" property="name" value="jsp" />
is for setting beans and maps.

<%
String[] language={"asp","jsp","php"};
%>

The above is not a bean, is it not?

Hi Ner,
Are you mixing up the EL [] operator with <c:set target="{myMap}" property="theKey" value="newValue" />

As far as I know, for EL [], you can use Bean, Map, Array and List.
For, the Dot (.), you can use Bean and Map.

But for <c:set var> and <c:set target>, my previous post holds.

Hey Ner,
<c:set> with target attribute is for map or bean. If the el given for the target attribute returns anything other than a bean or a map, the container throws an exception. <c:set> with var attribute is for setting a new value or updating the value for an existing attribute in any scope.

No where is the context of a list or an array coming into picture.

Correct me if I am wrong!!
