Cant get css, js files if not using .do extension
Dear all, I had met a strange problem: If I modified the struts.xml file and I dont want to use .do extension for actions. I set it as "/* ". For example, the previous link is http://localhost:8080/test.do. Now after modification it becomes: http://localhost:8080/test. But when I restart the server and run it, the error appears in the jsp file which I include a css file, the link is like "../css/main.css". The console said: 15545 [http-8080-2] ERROR org.apache.struts2.dispatcher.Dispatcher - Could not find action or result There is no Action mapped for namespace / and action name main.css. - [unknown location] I am sure that the link for this css file is correct.(If I still configured the action extension to .do, all things run correctly...) Could any people tell me how to solve this? Thank you very much! -- Best Regards, Licco

Dear All, I want to do something like this:
in my action i create:
List textFields = new ArrayList();
and i tried to write set method in 2 ways:
1. public void setTextFields (List textFields)
2. public void setTextFields(String text)
{
textFields.add(text);
}
and in my jsp, i want to get something like this:
But I found that for both setter methods, there are errors:
com.opensymphony.xwork2.util.OgnlValueStack - Caught an exception while

Dynamic s:checkbox name?
Dear All, I am confusing about how to write dynamic s:checkbox names in s2. For example, I want to achieve the result as: etc. The main problem is that i dont know how to write the right ognl expression in the code above(around the "?" position). Can anyone help me? Thanks in advance. -- Best Regards, Licco
Re: How can these query data be got?
Hi Dave,
Thanks for your quick reply. Suppose that I input this link
"xxx/welcome.do?param1=hello¶m2=world¶mList=element1¶mList=element2¶mList=..."
into the link bar in the browser and run it. How can S2 knows to put "hello"
into param1 and "world" into param2 in the welcome action object?
Could you please kindly explain the procedure? Or lets say, if I define
another field "param4", why not giving "hello" to "param4" instead of
param1?
Besides, suppose that I just run this link
"xxx/welcome.do?param1=hello¶m2=world¶mList=element1¶mList=element2¶mList=..."
in the browser, only the default method "execute" will be called, right?
Thanks a lot!

How can these query data be got?
Hi All,
I am quite confusing about this problem:
Suppose this is an action:
public class welcome implements Action
{
private String param1;
private String param2;
private List paramList;
getters
setters
public String execute() throws Exception
{
paramList = new ArrayList();
return SUCCESS;
}
}
Then if I input the URL:
xxx/welcome.do?param1=hello¶m2=world¶mList=element1¶mList=element2¶mList=...
I found that param1 will be given the value "hello", param2 will be given
the value "world" but of course paramList will not be given
element1,2,3...etc. I want to ask:
1. How can Struts2 get this value and give them to the parameters in the
action. As param1 and param2.
2. How to solve the paramList problem that I can put a list of the same
kind of data into a dynamic list as paramList when I type / click the URL
like the example I gave above?
PS: This will be used in pagination especially in the "page" tag which I
wrote myself.
Thanks a lot in advance!

Re: Pagination Questions
Hi Adam, Thanks for your reply. I am doing pagination like this now since I found that using index to do searching from a range of record is quite fast, much faster than I thought before.

S2 Side Integrated with UI side(js + ajax)
Dear All, I am a newbie to Struts2. I found that tag library in Struts2 is quite useful and convenience. But I have some problems with integration with our UI developer. Since he doesn't think that Struts2' tags are good looking enough and he want to develop the UI by his way. But if we dont use S2's tag, I found that I dont how to get values from action class. (S2's tag will get them from valueStack automatically.) For example, I can make a CheckboxList by using:I know that xxInitList will be get from the valueStack automatically. But my UI developer want me to show the items in the xxInitList by using in HTML and then he will make the checkboxlist by nicer solution. So how can I solve this problem by getting values from action by not using S2 tags? And what's the best practise to integrate UI side code? This question may be quite trivial for you guys...But I am really confused with it...Thank you very much in advance! -- Best Regards, Licco
