Java Development Tools

Hello guys, am having a Servlet that feeds an active image component with the picture.

in this Servlet in need 2 parameters :

       String imageId = request.getParameter("imageId");                                      
       String accountId = request.getParameter("accountId"); 

in filled (/imageservlet?imageId=#{bindings.PhotoId.inputValue}?accountId=#{sessionScope.accountId}) in the image source .

it doesnt work so far,, is this the right syntax for the source ?? or i cant request 2 parameters this way ??

am using JDev 12.c

thanks in advance, Saidi.
