Access and print HTTP request query string parameters via EL in JSP page -

i need pass request parameter 1 jsp jsp page this:

<a href="cv.jsp?type=alaacv">alaa</a> 

however, when try access below, doesn't print anything.

<c:set var="selectedcv" value="${type}" scope="request" /> <c:out value="${selectedcv}" /> 

how caused , how can solve it?

you need access ${param} implicit el object referring request parameter map (which map<string, string>; if need map<string, string[]> multi-valued parameters, use ${paramvalues} instead).

<c:set var="selectedcv" value="${param.type}" /> <c:out value="${selectedcv}" /> 

the ${param.type} resolves request.getparameter("type").

you can below without need <c:set>:

<c:out value="${param.type}" />
