Hello,I am having some problems with getting a session attribut in my JSP. A have a JSP where the user can make a search based on information he must enter in a form. The result of the search must be displayed in a table. To display the result I do: <logic:notEmpty name="cautionVOs" scope="session"> <tr> <td> <div style="overflow:auto; height:100px;"> <table class="result"> <logic:iterate id="cautionVOs" name="remPayVO" type="RemPayVO"> <tr> <td><html:radio styleClass="radio" name="remPayVO" property="paymentId" value="<%= remPayVO.getPaymentId().toString() %>" onclick="forward ('prepare','/modifycautionmanagement.do','ModifyCautionForm');waiting();" /> </td> <td><bean:write name="remPayVO" property= "dateModifStatut" /></td> <td><bean:write name="remPayVO" property="modePay" /></td> <td><bean:write name="ModifyCautionForm" property= "compteFacturation" /></td> <td><bean:write name="remPayVO" property="montant" /></td> <td><bean:write name="remPayVO" property= "commentaire" /></td> </tr> </logic:iterate> </table> </div> </td> </tr> </logic:notEmpty> The problem is that I get the error javax.servlet.jsp.jspException: No Collection found, and i think i get it with <logic:notEmpty name= "cautionVOs" scope="session"> Here is a piece of my Action class: ***** ModifyCautionForm modifyCautionForm = (ModifyCautionForm)form; errors = modifyCautionForm.validate(mapping, request); purgeSession(request); RechercheCautionVO rechercheCautionVO = new RechercheCautionVO(); rechercheCautionVO.setCompteFacturation(modifyCautionForm.getCompteFacturation ()); rechercheCautionVO.setPaymentMethod(modifyCautionForm.getModePay()); rechercheCautionVO.setMontant(modifyCautionForm.getMontant()); rechercheCautionVO.setDate(date); rechercheCautionVO.setPaymentID(modifyCautionForm.getPaymentID()); rechercheCautionVO.setBanque(modifyCautionForm.getBanque()); rechercheCautionVO.setAgence(modifyCautionForm.getAgence()); rechercheCautionVO.setCompte(modifyCautionForm.getCompte()); rechercheCautionVO.setNumPiece(modifyCautionForm.getNumPiece()); Collection cautions = null; try { PaymentDelegate payDelegate = new PaymentDelegate(); cautions = payDelegate.getAccountCaution(rechercheCautionVO); log.debug("*** cautions size " + cautions.size()); log.debug("*** cautions is empty? " + cautions.isEmpty()); request.getSession().setAttribute( SESSION_REMPAYVOS, cautions); Collection col = (Collection)request.getSession ().getAttribute(SESSION_REMPAYVOS); log.debug("*** cautions is empty? " + col.isEmpty()); modifyCautionForm.setCautionVOs(cautions); Iterator it = modifyCautionForm.getCautionVOs().iterator(); while(it.hasNext()){ RemPayVO rpVO = (RemPayVO)it.next(); log.debug("paymentID: " + rpVO.getPaymentId()); } **** (SESSION_REMPAYVOS = "cautionVOs") When I look at the log I can verify that cautions is not null, and neither is the session attribute. But if i add <% Collection col = (Collection)request.getSession().getAttribute( "cautionVos"); %> in my JSP right before <logic:notEmpty name="cautionVOs" scope="session"> I get a java.lang.NullPointerException Somewhere between my action class and my jsp the session attribute is set to null.
Are you sure that it is the <logic:notEmpty> that is causing the problem? The reason I'm asking is that your <logic:iterate> doesn't seem to tie up with what you have in <logic:notEmpty> and doesn't match what you say your session attribute is. Looks to me like you have the "id" and "name" attributes the wrong way round - should be: <logic:iterate name="cautionVOs" id="remPayVO" type="RemPayVO"> Niall
Does anyone have some idea of what is happening?? Thanks in advance!! Marianne
