I'm trying to use a autocompleter that is to be built from a list (of
objects).

I want the objects id to be the value of the option and code to bethe label
to be shown in the autocompleter dropdown options.

I should be shown codes as select options in the dropdown and when I select
any of the code, the corresponding id should go as the value that has been
selected

Pointers on this would be of great help

I understand what you're trying to do, I don't understand what specific aspect you're having a problem with. You said you implemented the action with a hard-coded list. An action that uses a database instead is almost exactly the same, but it accesses a database instead of using a hard-coded list.

The Struts 2.0 autocompleter docs [1] summarize the usage of the tag; the action will be called with the current value in the text box. You use that partial value to do a database search (or filter an existing list, or however you'll implement that part).

Well, IMO you don't use ANY JSTL tag in the code snipplet here.

That would be here [1].

How? What would we use to diagnose the problem?

Hi,

I would suggest experience or some insight to the requirements of
struts2 that i don't have.
yes, you can get my code, but since it is quite the same than some
iterate-examples that work (at least if you follow their authors) that
part should be correct.

the action:

  public class GetEntriesAction extends ActionSupport {
    public String execute() { return "success"; }
   
    public ArrayList<EntriesBean> getEntries() {
      EntriesBean bean = new EntriesBean();
      bean.setAuthor("blubb");
      ArrayList<EntriesBean> ret = new ArrayList<EntriesBean>();
      ret.add(bean);
      return ret;
    }

    public List<String> getTest() {
      ArrayList<String> ret = new ArrayList<String>();
      ret.add("hello1");
      ret.add("hallo2");
      return ret;
    }
  }

The Entries-Class

  public class EntriesBean {
    private String author;
   
    public String getAuthor() { return author; }
  }

The JSP

|<s:iterator value="entries" id="curEntry">
 <s:property value="author" /></td>
 objecttest
</s:iterator>
<s:iterator value="test" id="curtest">
 <s:property />
 stringtest
</s:iterator>|

The test with the stringarray works, the test with the entries class doesnt.

I created the project by importing the blank 2.0.11 war into eclipse.
maybe that helps too.

Greetings,
Alex

S2 is just another web framework; no special configuration is necessary other than creating a web application project and putting the appropriate libraries into /WEB-INF/lib.

You may also use Maven to create a skeleton S2 project, including Eclipse project files; I'm not very familiar with the process though.

AFAIK Velocity works fine, although I haven't tested it for awhile.

It might be helpful to provide information detailing what, exactly, is happening that's wrong.

Hi,

I want to have two action classes, the first class called SearchAction will
search from database and show results in a jsp page. When user click some
row I want to pass that value (through a session) to another action class
called EditAction which will then show that object for editing. Is this
possible to define in Struts 2?

Pass *what* value? You can't "pass an object" to an action. You could pass an ID. You could use that to *retrieve* an object from the session, if your application is small enough that it can keep all those objects in session for all the users.

It's more likely you'd use the ID to get the full object from a database, though.

Dave

Hi,

I want to read object from database in the first action class (i.e. Fruit
fruit) to store it into session and then to call other action class method
for editing of that method, is it possible ?

Oh, I thought you said you were retrieving a *list* of objects and wanted to edit a particular one (the one the user clicks on).

If the object is already in session of course you can retrieve it from the session in the second action.

I'm pretty skeptical that we're communicating accurately here, though.

Dave

Hi Dave,

Yes that's what I want. The first action search in database and show the
list of Fruits. Then user click on one and that concrete Fruit object is
passed to other action for editing.

All you can pass in an HTTP request is a string.

You can *use* that string to create or retrieve an object.

Dave

But could I pass object through session object ?

If you're using a persistence framework (Hibernate, JPA, etc.) then No.

During after the first request the EntityManager will be closed, so when
you access it during the second request updates will not be propagated
to the database.

I don't know how to answer that.

If you have a list of objects in the session you could use the id to retrieve the object from the session (if it's in a map, or if you iterate over the list and search, etc.)

How would you put the object into the session from the browser?

Yes, EntityManager will be closed, but it always closes whenevery you do
something (read/write) your object from database, isn't it ? When I read for
example Fruit (id=1) from database, change it and try to save it will know
with new EntityManager instance to save it because of id number ?

When user clicks on one object in jsp list, its id is set in action class and
the method in action class is called which will based on that id choose from
the list and put that object in session. Then with redirect-action (somehow)
I will call another action for editing that object from session. Is this
scenario O.K. ?

I guess I'm going about this the wrong way. I want the other developers on
the team to be able to write actions without worrying about adding in code
to support the in-house framework, so an interceptor that could execute
after the action seemed like a fit - except that it can't modify the
request. So is there a better approach that could still keep my actions
clean?

I think you may have missed the nub of my gist; I'm saying that the colored box at [1] with the blurb about the PreResultListener may be what you need.

Hi,

Does anyone have any experience of using the execute and wait interceptor in
a clustered environment.
I see the interceptor put the BackgroundProcess object in the session. This
object has a reference to among other things the action. If the app server
is using a DB to share session information I am wondering about the
performance of serializing this object to and from the DB for each "update"
refresh ?

Many thanks
Ian

Hello. I'm using Struts2 with Ajax support and I'm able to refresh the
content of a div with remote content via Ajax calls.
Anyway I've a problem: when the div is refreshed, the page is scrolled up to
the top, like if the entire page is refreshed.That's it, if I scroll down
the page and then i click on the ajax anchor, the div is refreshed with the
remote content, but the page is scrolled up...
The code is very simple:

<s:url id="ajaxCallUrl" action="CreateOverviewTable">
      .... some params
</s:url>

the button:

<s:a href="%{ajaxCallUrl}" theme="ajax" targets="summary_div" > ....

the div:

<s:div theme="ajax" id="summary_div" href="%{ajaxCallUrl}"
indicator="indicator1"/>

....

and finally, the action mapping:

<action name="CreateOverviewTable" class="actions.stats.StatisticsGen"
method="createOverviewTable">
 <result name="success">/pages/OverviewTable.jsp</result>
</action>

The div is refreshed with the new table (OverviewTable.jsp) but the page is
scrolled up. How can I avoid that?

Thank you!

OK...I'm getting there! I got the idea: loadOnTextChange.

so I ended up with this JSP:

<s:url id="json" value="/groupManagement_potentialList.do" />
<s:autocompleter href="%{json}" loadOnTextChange="true"
loadMinimumCount="1"  showDownArrow="true" name="userKeys" theme="ajax"
autoComplete="true"/>

BUT where is the list?!?!?!
I can invoke a method, but how does the statement above knows which list to
use?!
And what should the potentialList method return?

THANKS for any pointers!

I have a JSP that uses an ActionTag <s:action> to call a Struts 2 action
class directly from the JSP. But in the action class, the HTTP response
has already been committed. This makes it impossible for me to set cookies
from my action class.

I tested this by calling HttpServletResponse.isCommitted() is my execute()
method of my action class, and it returns true.

Is this a bug? Why is the response committed if the JSP hasn't finished
rendering?


--somePage.jsp--
<s:action name="someAction" executeResult="true"
ignoreContextParams="false" />

--struts.xml--
<action name="someAction" class="com.dev.MyAction" method="execute">
  <result>/page.jsp</result>
</action>

--MyAction.java--
public String execute()
{
System.out.println("response.isCommitted() = " + response.isCommitted());
//this prints true
}



Thanks,
David

Hi Everyone,
 
  I faced a tedious problem in manipuluating s:datetimepicker in my page.
It hasn't focus set and events are not fired.

Anyone help me to give the solution.


Regards,

Ramesh K

That's not much to go on.

You have the <s:head...> tag? Your S2 mapping is correct such that it's serving the Dojo files?
