Jsp Expression Language Problem

Question

I have a jsp in which there is something like this

${pageContext.request.parameterMap.instanceNo[0]}

I want to iterate through each of its value.

I tried the below code but doesn't work

    <s:iterator id="test" var="" value="${pageContext.request.parameterMap.instanceNo[0]}">
        Hello
    </s:iterator>

Answer 1

Since you already denoted the index using [0], it returns the first value as String, not all values as String[].

Don't you maybe want to iterate through ${paramValues.instanceNo} instead?
