将字符串数组作为隐藏值从一个jsp传递到另一个jsp

Question

I am trying to pass String array from one jsp to another. I am using JSTL in my JSP. In my first JSP i am doing like this

<c:if test="${fn:length(empBean.additionalEmailAddr) gt 0}">
                <c:forEach begin="0" end="${fn:length(empBean.additionalEmailAddr) - 1}" var="ind" >
                    <input type="hidden" name="inbdAdditionalEmailAddr" value="${empBean.additionalEmailAddr[ind]}"/>
                </c:forEach>
            </c:if>

and trying to access the values in another jsp as follows

<%
    String[] inbdAddEmlAddr = request.getParameter("inbdAdditionalEmailAddr");
%>

and i am planning to use JSTL to print the array values.

In the second jsp i am getting type mismatch error. Please help.

Is this the right approach ? Any help is appreciated

Thanks

Answer 1

request.getParameter() returns a String which the code attempts to assign to a String[] , causing the exception.

Use request.getParameterValues('inbdAdditionalEmailAddr'); to retrieve parameters as an array.

See the documentation .
