Hi,

I use Struts2, Spring and hibernate in my project wanted to integrate Struts menu, the dynamic roles from oracle db. I followed the link

http://demo.raibledesigns.com/struts-menu/dynamicMenu.jsp

I copy pasted the code snippet into an action

import java.util.Map;

import javax.servlet.jsp.jstl.sql.Result;

import net.sf.navigator.menu.MenuComponent;

import net.sf.navigator.menu.MenuRepository;

public class MenuBuilderAction extends BaseAction {

/**

private static final long serialVersionUID = 1L;

MenuRepository repository = new MenuRepository();

// Get the repository from the application scope - and copy the

// DisplayerMappings from it.

MenuRepository defaultRepository = (MenuRepository) getSession()

.getAttribute(MenuRepository.MENU_REPOSITORY_KEY);

//repository.setDisplayers(defaultRepository.getDisplayers());

Result result = (Result) getSession().getAttribute("menus");

Map[] rows = result.getRows();{

for (int i = 0; i < rows.length; i++) {

MenuComponent mc = new MenuComponent();

Map row = rows[i];

String name = (String) row.get("name");

mc.setName(name);

String parent = (String) row.get("parent_name");

System.out.println(name + ", parent is: " + parent);

if (parent != null) {

MenuComponent parentMenu = repository.getMenu(parent);

if (parentMenu == null) {

System.out.println("parentMenu '" + parent

+ "' doesn't exist!");

// create a temporary parentMenu

parentMenu = new MenuComponent();

parentMenu.setName(parent);

repository.addMenu(parentMenu);

}

mc.setParent(parentMenu);

}

String title = (String) row.get("title");

mc.setTitle(title);

String location = (String) row.get("location");

mc.setLocation(location);

repository.addMenu(mc);

}

getSession().setAttribute("repository", repository);

}

My menu-config.xml

<?xml version="1.0" encoding="UTF-8"?>

</Displayers>

<Menus>

</Menu>

</Menus>

</MenuConfig>

ApplicationConfig.xml

<value>/WEB-INF/menu-config.xml</value>

</property>

</bean>

When i run my jsp i get

javax.servlet.jsp.JspException: The menu repository could not be found.

Kindly help

thanks,

Gokul

Instead of registering it in your Spring applicationContext, I'd try using the MenuContextListener in your web.xml:

<listener-class>net.sf.navigator.menu.MenuContextListener</listener-class>

</listener>

If that doesn't work, look for errors on startup - you might be missing some required JARs.

Thanks a ton for your reply Matt. I do not get the error now, but it is redirecting to some other page, while i work on that.

Can you please guide me on how i can fetch my menu items from database instead of menu-config.xml

thanks,

Gokul

Change the following to fetch items from your database and iterate through them to build up your MenuComponent objects.

Result result = (Result) pageContext.getAttribute("menus");

Map[] rows = result.getRows();

for (int i=0; i < rows.length; i++) {
