Hi,
When I set a value in my interceptor,I could not get it in a jsp.
How to do that?
### my interceptor
public class HogeIntercepter extends AbstractInterceptor {
@Override
public String intercept(ActionInvocation invocation) throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("key", "aaa");
return invocation.invoke();
}
}
### jsp
<c:out value="${key}"/> -> it's return 0.
<s:property value="key" /> -> it's return 0.
<% out.println(request.getAttribute("key")); %> -> return "aaa"
FYI.
I also refered the following the URL
http://stackoverflow.com/questions/1804266/struts2-understanding-the-value-stack
but I could not get it in a jsp.
public String intercept(ActionInvocation invocation) throws Exception {
Map<String, Object> map= new HashMap<String, Object>();
map.put("key", "aaa");
invocation.getStack().push(map);
return invocation.invoke();
}
Thanks.
