RE: [Struts2] problem with s:select tag
hi Raghuveer
you can solve your problem through call prepare() method again means
in action method before return String like SUCCESS OR INPUT OR LOGIN
call prepare() method once again it will display select component values
perfectly as normally.

Subject: [Struts2] problem with s:select tag
Hi,
I have a getting problem in using s:select tag. Need some help if anyone
used s:select before.
This dropdown is populated dynamically. When form is loaded initially
dropdown is getting populated perfectly. No issue here.
But when we submit the form and some of the validations fail then page is
not getting displayed correctly. This is because dropdown values are not
coming back after the form submit. Not sure what need to be done to bring
back this dropdown values.
I can see below error in the log.
Servlet.service() for servlet jsp threw exception
tag 'select', field 'list', name 'user.country': The requested list key
'countryList' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
Here is my jsp code for this issue:
s:select name=user.country headerKey=-1 headerValue=Select Country
cssClass=textbox1
list=countryList listKey=code
listValue=name required=true /
Pl. let me know if you need some more information.
Thanks in advance.

Re: Invalidating a session using JAVASCRIPT
Hi Sahil, I believe this can be done by implementing the HttpSessionBindingListenerInterface.The HttpSessionBindingListener interface is implemented by the classes whose objects need to receive notifications whenever they are added to or removed from a session. We do not have to inform the container about such objects explicitly via the deployment descriptor. Whenever an object is added to or removed from any session, the container introspects the interfaces implemented by that object. If the object implements the HttpSessionBindingListener interface, the container calls the corresponding notification methods Rajasekhar Cherukuri Tata Consultancy Services Limited Air-India Building 11th Floor, Nariman Point , Mumbai - 400 021,Maharashtra India Mailto: [EMAIL PROTECTED] Website: http://www.tcs.com Sahil Gupta [EMAIL PROTECTED] 03/21/2006 04:08 PM Please respond to Struts Users Mailing List user@struts.apache.org To user@struts.apache.org cc Subject Invalidating a session using JAVASCRIPT Hi, Can anyone tell me how to logout a user (invalidate his Session) when a user directly closes his browser window.

Re: Problem with request.setAttribute
Hi, When you use request.setAttribute() in Action, it is the same request which goes to JSP also. So, you are able to get the values in JSP through request.getAttribute(). But when you use request.setAttribute() in JSP and submit the form, then a new request is generated with the values that are contained in the current form and that new request erases all the previous values. If you want to use these values in the Action also, you need to set them to session rather than request.

Re: difference between setAtttibute and setPatameter
Hi, There is nothing like request.setParameter(). When ever you submit a form (say JSP), all the controls in the form like textbox, checkbox, textarea etc..will be submitted to the Action or Servelt with the names given to them and these values can be retrieved through request.getParameter(name). Here the name is the name given to each control in JSP. On the other hand request.setAttribute() is some thing through which the user can explicitly store the required information. For example, if you use request.setAttribute(MY_ATT, new Interger(4)) in either Action or Servlet, then you can retrieve the value in JSP through request.getAttribute(MY_ATT).

RE: query string parameters problem
The scope of the ActionForm is session means that the last submitted ActionForm will remain in the session till the session ends. In you case, even though the ActionForm is getting populated with the values for the first time, those are getting overridden by the second request and the second request is not taking the values of name and age in the query string (As the querystring URL is getting overridden by /submit.do).

Re: unknown field in struts-config.xml
Hi Alex,
Unknown=true is a special attribute which is useful in
directing the unknown requests to the applications to a specific page. For
example if you hit the URL of your application with
http://localhost:7001/App/someThing.do and if this someThing.do is not
a valid action in your Application App then it will be directed to an
action whose unknown=true in the struts-config.xml. There can be only
one action with this unknown=true. The default value is false and it
does NO harm to the action if explicitly unknown=false is specified.

Rajasekhar Cherukuri

unknown field in struts-config.xml
Hello all!
I am new to this mailing list. Actually this is my first post here.
I have a problem regarding the struts-config.xml. I am using xdoclet to
generate it. The situation is the following: The tags in the class as as
follows:
/**
*@struts.action

*name=LoginForm
* scope=request
* input=/jsp/login/loginScreen.jsp
* validate=true
* @struts.action-forward

*/
public class LoginAction extends Action
{
..
What is generated in the struts-config.xml is as follows:
action
path=/login
type=com.am.struts.wamp3.user.presentation.LoginAction
name=LoginForm
scope=request
input=/jsp/login/loginScreen.jsp

Re: Handling invalid sessions
Hi, The best way is to write a Base Action class and extend that class for all your Action classes in your application. Place a check in the execute method of the Base Action class and if it is a success then call an abstract method in the Base Action class which will be implemented by all your Action classes. If it is a failure (means there is NO required information in the session), then forward to a login page or failure page.

That is why i have clearly specified that you have to implement an abstract method in the base class. which will be implemented in all your classes and that method will be called explicitly from Base Action class.

Right? Then, as far as I know, that execute() in Base Action will not be executed.. Peru Cheppanu [EMAIL PROTECTED] wrote: Hi, The best way is to write a Base Action class and extend that class for all your Action classes in your application. Place a check in the execute method of the Base Action class and if it is a success then call an abstract method in the Base Action class which will be implemented by all your Action classes. If it is a failure (means there is NO required information in the session), then forward to a login page or failure page.

Re: Select first in Options list
Hi, Do not use selected for any option. By default automatically, the first option will be selected and your purpose will be solved.

Re: ActionForm validate() - what Action does the controller call?
If the validate method returs non empty ActionErrors object, the control will go to the JSP specified in the input attribute of the corresponding action element in struts-config.xml . Thanks, Rajasekhar Cherukuri Please respond to Struts Users Mailing List user@struts.apache.org To Struts Users Mailing List user@struts.apache.org cc Subject ActionForm validate() - what Action does the controller call? When my ActionForm returns a non-empty ActionErrors object, where does control go to? i.e. i read from the struts site: When the properties of this bean have been populated, but before the executemethod of the Action is called, this bean's validate method will be called, which gives the bean a chance to verify that the properties submitted by the user are correct and valid. If this method finds problems, it returns an error messages object that encapsulates those problems, and the controller servlet will return control to the corresponding input form. Otherwise, the validatemethod returns null, indicating that everything is acceptable and the corresponding Action.execute method should be called. (my bold) I guess I don't understand what 'corresponding input form' means? Presumably the controller needs to call some Action, how do I know / specify which one?

Re: Base action class
It was a good idea to put the user logging check in the BaseAction class. This will be used as a firewall before allowing to access any resource (Action class). The required code for User Information check can be put in the execute method and another method like delegateToExecute(..) can be made abstract and this method can be called as the last statement in BaseAction's execute method. if the check is successful, the control goes to the delegateToExecute(..) method for the requested class where you can put ypur regular code. Since delegateToExecute(..) will be made abstract, that needs to be implemented in all teh actions which import the BaseAction. Thanks, Rajasekhar Cherukuri Please respond to Struts Users Mailing List user@struts.apache.org To user@struts.apache.org cc Subject Base action class Hello, I am trying to use a BaseAction class for my action, and i have been wondering what to put in there; As for now, i have put the basic stuff there like finding a forward for a database faillure and so on.. (like in the mailreader example by the way). Also, i have put a method that retrieves a handler from the servlet context that all actions need. Is this a good idea? I wonder whether it's a good idea to do authorization in the base class by implementing an abstract execute method that will check whether a user is logged in.. All action classes then will first call this abstract execute method. What do you put in base classes?
