Thanks for your post Raghu,
I changed the code but then I received the following exception:
org.apache.struts.chain.commands.InvalidPathException: No action config
found for the specified url.
org.apache.struts.chain.commands.AbstractSelectAction.execute(AbstractSelect
Action.java:71)

The thing is MenuAction handles the Menu, that's why it initialize
MessageList when some choose Message History menu.
Here's a extract:
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest servletRequest,
HttpServletResponse servletResponse) throws
Exception {
int menuOption = (Integer)
PropertyUtils.getSimpleProperty(actionForm,
"menuOption");
String forward = "";
UserTO user;
try {
switch (menuOption) {
case MenuConstants.HOME:
forward = "home";
break;
case MenuConstants.MESSAGES_HISTORY:
user =
(UserTO)
servletRequest.getSession().getAttribute("user");
MessageListTO messages = new
MessageDAO().getMessages(user.getClientId());
servletRequest.getSession().setAttribute("messageList",
messages.getMessageList());
DateTO dateRange = new DateTO(2008);
servletRequest.getSession().setAttribute("dateRange",
dateRange);
DateUtil dateTo = new DateUtil();
dateTo.setDay(dateTo.getCurrentDay());
dateTo.setMonth(dateTo.getCurrentMonth());
dateTo.setYear(dateTo.getCurrentYear());
servletRequest.setAttribute("dateTo",dateTo);
forward = "messages";
break;
case MenuConstants.SEND_MESSAGE:
forward = "sendMessage";
break;
default:
forward = "home";
break;
}
} .

Hi, everyone
I have problems linking displaytag with action/form/struts-config.xlm.
This is what I have:
MenuAction
- initialize the arraylist "messageList"
- servletRequest.getSession().setAttribute("messageList",
messages.getMessageList());
- forwards = "Message.jsp"
Message.jsp
pagesize="16" cellspacing="0">
When I click next on paging-menu I've got
java.lang.NullPointerException
at org.apache.jsp.WEBSITE.Messages_jsp._jspService
I read on other post to set displaytags' attribute requestURI="" but it
doesn't work either. I know I have to configure something on
struts-config.xlm and create an action class associated with this.
I'll appreciate any help you can give me on this.
Best regards,
Francisco
PD. I'm using Tomcat as application server
