"list" is not defined in a way that the EL can get at it. If you add it as an attribute it should work. Something like:

Hi,

you are setting values into list..then you try to print it..right?

you do this in servlet..then you forward to jsp page using request.settAttribute("key",list);

then in jsp something like this:

<c:forEach var="value" item="${list}">
${value}
</c:forEach>
now it will work...(please import jstl properties )

thanks & regards,
