Nested lt;c:foreachgt;

defaultMenu.jsp

Code:
lt;%@taglib prefix=quot;cquot; uri=quot;jstl/core_rtquot;%gt;

lt;%@taglib prefix=quot;cquot; uri=quot;jstl/core_rtquot;%gt;

lt;c:forEach items=quot;${sampleList}quot; var=quot;menuquot;gt;

lt;ligt;${submenu.link}lt;/ligt;
lt;/c:forEachgt;
lt;/ulgt;
lt;/ulgt;
lt;/c:forEachgt;
MenuController

Code:
protected ModelAndView handleRequestInternal(fromServletRequest request,
fromServletResponse response) throws Exception {

logger.info(quot;Initializing Menuquot;);
Listlt;Menugt; sampleList = new ArrayListlt;Menugt;();
Listlt;SubMenugt; subMenuList = new ArrayListlt;SubMenugt;();
for (int i = 0; i lt; 15; i++) {
Menu menu = new Menu();
menu.setLink(quot;Menu quot; + i);
for (int x = 0; x lt; 10; x++) {
SubMenu subMenu = new SubMenu();
subMenu.setLink(quot;SubMenu quot; + x);
}
menu.setSubmenu(subMenuList);
sampleList.add(menu);
}

return new ModelAndView(quot;defaultMenuquot;, quot;sampleListquot;, sampleList);
}
Menu.java

Code:
public class Menu{
private String link;
private Listlt;SubMenugt; submenu;

public String getLink() {
return link;
}

public Listlt;SubMenugt; getSubmenu() {
return submenu;
}

public void setLink(String link) {
this.link = link;
}

public void setSubmenu(Listlt;SubMenugt; submenu) {
this.submenu = submenu;
}
}
SubMenu.java

Code:
public class SubMenu extends BaseModel {
private String link;

public String getLink() {
return link;
}

public void setLink(String link) {
this.link = link;
}

}
How do I access a List inside another list in Spring? I would like to have the effect similar below

HTML Code:
lt;ulgt;
lt;ligt;Menu 0lt;/ligt;

lt;ulgt;

lt;ligt;SubMenu 0lt;/ligt;
lt;ligt;SubMenu 1lt;/ligt;
lt;ligt;SubMenu 2lt;/ligt;
lt;ligt;SubMenu 3lt;/ligt;
lt;ligt;SubMenu 4lt;/ligt;
lt;ligt;SubMenu 5lt;/ligt;
lt;ligt;SubMenu 6lt;/ligt;
lt;ligt;SubMenu 7lt;/ligt;
lt;ligt;SubMenu 8lt;/ligt;
lt;ligt;SubMenu 9lt;/ligt;

lt;/ulgt;
lt;/ulgt;
However, I am getting an error

If I remove the inner lt;c:forEachgt;, it works fine, however, it only iterates the Menu part.

raseryu,

Not sure what's going on, but have tried using a different taglib declaration?

For 2.4/2.5:Code:
lt;%@taglib prefix=quot;cquot; uri=quot;jsp/jstl/corequot; %gt;
For 2.3:

Code:
lt;%@taglib prefix=quot;cquot; uri=quot;jsp/corequot; %gt;
instead ofCode:
lt;%@taglib prefix=quot;cquot; uri=quot;jstl/core_rtquot;%gt;
AFAIK, using the *_rt taglibs is not recommended.

Hope that helps,
