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
Dynamic TextFields in Struts 2
Dear All, I want to do something like this:
in my action i create:
ListString textFields = new ArrayListString();
and i tried to write set method in 2 ways:
1. public void setTextFields (ListString textFields)
2. public void setTextFields(String text)
{
textFields.add(text);
}
and in my jsp, i want to get something like this:
s:iterator ...
s:textfield name=textFields[%{#status.index}]/
/s:iterator
But I found that for both setter methods, there are errors:
com.opensymphony.xwork2.util.OgnlValueStack - Caught an exception while
evaluating expression 'test_string[0]' against value stack
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:547)
Can anyone help me on how to create such a dynamic textFields (Considering
action implementation)? Thanks in advance!

Hi,
you dont have to explicitly add the values to the list in the setter
methods, since the framework will do that for you ,
also you dont have to explicitly provide the index in the property field
(name) (even though it will work with explicit indexing as well) . refer the
fallowing code for help , make sure you have the getters and setters
created in your model or action respectively.
s:iterator value=trainingSessionDetails
id=trainingSessionDetailsL status=status
tds:textfield name=trainingSessionName
id=sessionNameL
value=%{#trainingSessionDetailsL.sessionName}
size=8/s:textfield/td
tds:textarea name=trainingSessionDescription
id=sessionDescriptionL
value=%{#trainingSessionDetailsL.sessionDescription} //td
tds:textfield name=trainingSessionStartDate
id=sessionStartDateL%{#status.index}
value=%{#trainingSessionDetailsL.sessionStartDate}
size=16 //td
tds:textfield name=trainingSessionEndDate
id=sessionEndDateL%{#status.index}
value=%{#trainingSessionDetailsL.sessionEndDate}
size=16 //td
/tr

Re: Dynamic s:checkbox name?
Got it, quite useful. Thanks for all you guys' help!
2009/1/18 abhijit.sulh...@gmail.com
Makes perfect sense if interested in matching the values from checkbox
list. Another variation, I think in that case would be to use the
'fieldValue' instead of name; that way the set values can be easier
to retrieve as a list using the name encapsulator.
s:iterator value=test_list status=status
s:checkbox name=test_string value=true fieldValue=%{top}
/s:iterator

Thanks,

Nuwan,
I'm not sure if that is what he is intending. It will work, but for what
seems
to be the wrong reasons. If test_list contains the values to iterate
over,
then I would use those, rather than the loop index.
s:iterator value=test_list status=status
s:checkbox name=%{'test_string_' + top} value=true
/s:iterator
This is a slightly different variation of the OGNL, as I enclosed the
whole
expression. Also, top will point to the value on the top of the Value
Stack,
which will contain the value pushed onto it by the s:iterator tag.

Dynamic s:checkbox name?
Dear All, I am confusing about how to write dynamic s:checkbox names in s2. For example, s:iterator value=test_list status=status s:checkbox name=test_string_? value=true /s:iterator I want to achieve the result as: s:checkbox name=test_string_0 value=true s:checkbox name=test_string_1 value=true s:checkbox name=test_string_2 value=true s:checkbox name=test_string_3 value=true s:checkbox name=test_string_4 value=true 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=helloparam2=worldparamList=element1paramList=element2paramList=...
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=helloparam2=worldparamList=element1paramList=element2paramList=...
in the browser, only the default method execute will be called, right?
Thanks a lot!

The first issue I see is that you're creating a new list in the execute()
method. The execute() method is executed after the interceptors set the
action properties from the form data--so you're wiping out the work the
interceptors did.

These two action classes have field:

These two action classes have getter and setter for the field named page:

Why does I get such exception?

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=helloparam2=worldparamList=element1paramList=element2paramList=...
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. So I just use your suggested solution. 2008/11/30 Adam Ruggles [EMAIL PROTECTED] Personally I think it would be a bad idea to buffer the data from the db, since most users when performing a search will only look at the first page of results. It would be better to simply return a limited set of results from the DB. Otherwise you might be fetching data the user will never see. What I usually do is create an object that stores a list of the current result set and the total number of results. This object I create in the data layer and requires two db calls. One to get a limited list of results and the second to get the total item count. In the action I have an offset and resultsPerPage variable that I pass to my data layer. I don't know what database you're using but most allow you to limit the results, using an offset and number of results. KE LI-2 wrote: Dear All, I am currently working on pagination to the result of search result. I want to ask which solution is better? 1. After user chooses some criterias and then clicks the search button, the server will return the size of search result and the objects of first page of the search result. Then when user clicks the different page number, the server will get the data for that page from DB. But for this solution, it requires DB access when you click the page number. 2.After user clicks the search button, the server will get all the objects(like all the films which the user wanna.). Then when user clicks different page number, the server will just return the data from memory. This seems to reduce the DB access times. 3. Use some preload method to store the data for the next few pages in a buffer. Which solution will achieve a fast search and reduce the access load to the DB? Thanks a lot for your feedback!

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: s:checkboxlist list=xxInitList/ 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 li 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
