Subject: JSP read value from ActionForm
Hello,
May I know how to read a parameter value in JSP page for the following
situation please?
(1) Struts2Action.java
... String list_size = MGIn Java code on server sideMGpackage
org.apache.struts.webapp.exercise;MGpublic class TestBean extends ActionForm
{MGArrayListString list=new
ArrayList(5);MGlist.add(First);MGlist.add(Second);MGlist.add(Third);MGlist.add(Fourth);MGlist.add(Fifth);MGint
list_size=list.size();MGlog.debug(List size=+list_size);MG} MG(JSP
Client)MG%@taglib prefix=s uri=/struts-tags %
%@ taglib uri=http://struts.apache.org/tags-bean; prefix=bean % !--
useBean will reference the bean created from servlet -- jsp:useBean id=list
scope=page class=org.apache.struts.webapp.exercise.TestBean /
OR!-- to dynamically create the list bean in the jsp --
jsp:useBean id=list scope=page class=java.util.ArrayList / html
body!-- dynamically created Bean --%
java.util.ArrayList list = new java.util.ArrayList();
list.add(First);
list.add(Second);
list.add(Third);
list.add(Fourth);
list.add(Fifth);
pageContext.setAttribute(list, list, PageContext.PAGE_SCOPE);%size
is %= list.size() % s:select label=list
list=list
name=list
value=%{list}
multiple=true size=5//body/html
getter/setter for list_size
(2) result.jsp
s:select ...
size = %= list_size%
/
Is there a simple way to assign Struts2Action.list_size to s:select.size
filed in the result.jsp file?
Thanks a lot!
