Re: ReQ: Only one logged in session at a time for each user
Hi Guys They way i have done this is create a singleton class for logged on users and keep a hash of the usernames logged on. However when a user does not loggof the user is still in the hash, so what i do before a user tries to logon again is to check whether the session is valid . if it is then i give a mutliple loggon message, invalidate the session and create a new session. If the session is invalid i know he expired so i just logg the user on normally. Also at each request check for valid session. kayode Dosunmu From: Alvin Kutttikkat Antony [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: ReQ: Only one logged in session at a time for each user Date: Mon, 28 Jan 2002 16:22:39 +0100 Hi there, I am too interested on this.The suggestion is good.How can I get session object from the Id.I think one way is through HttpSessionContext class.

RE: ReQ: Only one logged in session at a time for each user
Hi Kayode Just a note, a Singleton will not work if you have a cluster of JSP containers serving your application. You would have to use the database or a stateful session bean if you want it to work in a distributed environment. You could try the application context, but I am not sure if the container will persist that to other servers.

Multiple beans
I am new to struts so excuse me if this is an incredibly naïve question, I have searched through the archive put am not sure what to even search on. I have multiple beans for a form an example would be contact.jsp where the ContactForm.java has the get and set methods for the contact e.g. firstName, lastName etc, I have a bean AddressForm to handle the contacts address/s with get and set methods (adress1, address2 and so on) and a bean for the phone details (PhoneForm.java) with the corresponding phone information. html:form action=contact html:text property=firstName size=30 maxlength=30 / html:text name=addressForm property=address1 size=30 maxlength=30 / html:text name=phoneForm property=phoneNumber size=30 maxlength=30 / In struts-config I have actionpath=/contact type=com.blah.blah.ContactAction name=contactForm scope=request validate=true input=/contact.jsp form-bean name=contactForm type=com.blah.blah.ContactForm/ form-bean name=addressForm type=com. blah.blah.AddressForm/ form-bean name=phoneForm type=com. blah.blah.PhoneForm/ However the result is Cannot find bean addressForm in scope null. If you could point me to some link with information it would be greatly appreciated. TIA Joe
Re: Form fields submitted multiple times...
If you are forwarding from Action to Actoin, the ActionServlet will
handle each request the same as the first.
If you do not want your ActionForm to be repopulated from the request as
you forward it around, the workaround is to put an readonly property on
the form. The public setters for your properties can then check this to
see if they should allow changes or not. The first action can then set
the ActionForm to readonly before forwarding it along.
public void setProperty(String property) {
if (isMutable()) {
this.property = property;
}
}
There's a SuperForm class in the Scaffold package in the contrib
folder that demonstrates this and some other techniques
[org.apache.scaffold.http.SuperForm].

Has anyone ever noticed the Set methods in the ActionForm invoked multiple
times (always using the values submitted from the html:form) from Action to
Action?
In our JSP, we have several buttons pertaining to the same form
(thisActionForm). Depending on which button was pressed, a different
action mapping is invoked from Struts:
action path=/handleButtons type=HandleButtonsAction
name=thisActionForm validate=false scope=session input=/home.jsp
forward name=updateDetailsButton
path=/updateDetails.do/
forward name=resetDetailsButton
path=/resetDetails.do/
forward name=calculateButton
path=/calculateAmounts.do/
forward name=deleteButton
path=/deleteDetails.do/
/action
action path=/resetDetails type=ResetDetailsAction name=thisActionForm
validate=false scope=session input=/home.jsp
forward name=success
path=/calculateAmounts.do/
/action
action path=/calculateAmounts type=CalculateAmountsAction
name=thisActionForm validate=false scope=session input=/home.jsp
forward name=success path=/details.jsp/
/action
We see the fields entered/changed in thisActionForm set before entering
the HandleButtonsAction class.
We also see the same field values set again before entering the
ResetDetailsAction class, as if the HTML form has been submitted a second
time.
The ResetDetailsAction resets some date fields on thisActionForm, by
invoking various Set methods.
We then see the original field values set a third time before entering the
CalculateAmountsAction class, clearing out the values reset in the
ResetDetailsAction
As anyone seen anything similar?
Is there an attribute we could use in the action element that would disallow
the form from submitting again and again and again?
Our current work around is to not use thisActionForm on any other actions,
except the HandleButtonsAction, and just grab thisActionForm off of the
session in ResetDetailsAction and CalculateAmountsAction, but we feel
that there's an easier way.
Sorry for the novel...

Re: Formatting Dates, Integers...
Pesonally, I recommend doing such things in the ActionForm. You can do them in the page, but that means modifying the page, and placing what is really business logic in the presentation tier. While it seems we are talking about how data looks, formatting it this way or that is really a business requirement. The part about stuffing the formatted string into HTML is the presentation tier. The J2EE blueprints call these helper beans or methods. Generally, I add a second getter to provide the formatted version. This does the same thing a tag would do, but is easier to write. The actual formatting code I would put into a library in the business tier that the ActionForm method would simply call. So you could add these without touching your existing methods, and just have the bean:write call these getters instead. Of course, if we are talking about display data, and you already have beans that render the formatted data, just use those. The ActionForms are only important for inputting data. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Java Web Development with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ Hudayioglu, Fehmi wrote: Hi fellows, I have searched the mailing list in hope to find a way to display a number in format (e.g:120.200,32). I couldn't find any solution. There were some messages proposing to play on the getter and setter methods. But, this is not a solution we imagine. Because we have some object properties in the Form Bean and their properties can be set by struts directly. So changing getter and setter methods requires tons of effort to modify our data classes and form beans which is of course NOT desirable. I also know that there is a DateTag library of Jakarta, which is yet in beta release. Therefore, my managers (regards to them) don't want to use beta releases. They don't want to modify struts tags neither. However, I believe this is quite straightforward way (hopefully they will be contended soon). So, 1. Do you have any clever solution for this common problem? 2. What necessary steps should I take in order to add a new Format attribute to the form:text and bean:write? 2.1 In case, I added necessary methods, how can I guarantee that struts set this formatted value to the property.

I have multiple beans for a form an example would be contact.jsp where the ContactForm.java has the get and set methods for the contact e.g. firstName, lastName etc, I have a bean AddressForm to handle the contact's address/s with get and set methods (adress1, address2 and so on) and a bean for the phone details (PhoneForm.java) with the corresponding phone information. html:form action=contact html:text property=firstName size=30 maxlength=30 / html:text name=addressForm property=address1 size=30 maxlength=30 / html:text name=phoneForm property=phoneNumber size=30 maxlength=30 / . In struts-config I have actionpath=/contact type=com.blah.blah.ContactAction name=contactForm scope=request validate=true input=/contact.jsp form-bean name=contactForm type=com.blah.blah.ContactForm/ form-bean name=addressForm type=com. blah.blah.AddressForm/ form-bean name=phoneForm type=com. blah.blah.PhoneForm/ However the result is Cannot find bean addressForm in scope null. If you could point me to some link with information it would be greatly appreciated.

Re: Template Question
Thanx Cedric, I realized that a few days later, so I used a .jsp with frames where one of the frames loads the page.
