Hi all, I start runnig my application with an Action (action.do) which access to the database to get a collection and send it to the JSP. The problem is : when I put validate ="true" in struts-config an error is detected (because fields in the JSP are blank) so the collection is null and the JSP is not displayed. The solotion I want : to display the JSP with errors, and also the collection(not null). Thanks....
