Hi
I'm new to JSTL and not quite new to Java. I think JSTL is the best thing
since sliced bread :-) but I'm having a problem. Probably this is a very
dumb question, but anyway...
(I tried the examples and they all work)
All I'm trying to do is set up a new iterator. Thus, I modify
org.apache.taglibs.standard.examples.startup.Init by copying
/**
* Array of Objects (String)
*/
String[] stringArray = new String[] {
"A first string",
"La deuxieme string",
"Ella troisiemo stringo",
};
sce.getServletContext().setAttribute("stringArray", stringArray);
and modifying it:
/**
* Array of Objects (String)
*/
String[] stringArray = new String[] {
"A first string",
"La deuxieme string",
"Ella troisiemo stringo",
};
sce.getServletContext().setAttribute("stringArray", stringArray);
/**
* Array of Objects (String)
*/
String[] storyArray = new String[] {
"A first string",
"La deuxieme string",
"Ella troisiemo stringo",
};
sce.getServletContext().setAttribute("storyArray", storyArray)
Then I modify DataTypes.jsp:
<h4>Array of objects (String)</h4>
<c:forEach var="string" items="$stringArray">
<c:expr value="$string"/><br>
</c:forEach>
<c:forEach var="story" items="$storyArray">
<c:expr value="$story"/><br>
</c:forEach>
I stop and restart Tomcat and open DataTypes.jsp in the browser, but I just
get the following error:
ReferenceError: "storyArray" is not defined.

etc. etc.
Probably I'm just being naive, but how exactly do you define a new object to
be used in JSTL? I couldn't find any further reference to the existing
stringArray in the source...
