Re: How to take object from the Action to jsp
.jsp pages have access to the a reference named application from which you can gain access to objects stored in your servlet context. I believe you should use the following method to access context scoped objects within your jsp pages. You can extract the reference to your treemodel with the following. % Node root = (Node) application.getAttribute(treemodel); % %= new DirectoryModel(root) % Or your way %= new DirectoryModel((Node)application.getAttribute(treemodel)) % At 06:36 PM 4/3/2002, you wrote: Hello, My question might sound naive but I really eed your answer.

RE: How to take object from the Action to jsp
Hi Constantina, Instead of servlet.getServletContext().setAttribute(treemodel,root); I use request.setAttribute(treemodel,root); In the JSP, instead of DirectoryModel((Node)servlet.getServletContext().getAttribute(treemodel) %. I use bean:write name=treemodel property=propertyOfNodeClass / to wirte one propierty into the generated html code, or % DirectoryModel((Node)this.pageContext.getAttribute(treemodel)); Hope That Help, Enrique. _ Enrique Rodriguez Lasterra -Mensaje original- De: Konstantina Stamopoulou [mailto:[EMAIL PROTECTED]] Enviado el: miercoles, 03 de abril de 2002 10:37 Para: Struts Users Mailing List Asunto: How to take object from the Action to jsp Hello, My question might sound naive but I really eed your answer.
