Re: Need some help with generateToken
I've got a question here. When you say somewhere in the Action, which action do you refer to ? The action that catches the form, or the action that forwards control to the form ? Thanks Jefferson Ted Husted wrote: Not much to it really. Before forwarding to the form that needs to be part of the transaction, just call saveToken(request); somewhere in the Action. If the form the Action forwards to uses the Struts html:form tag, it will write out the token for you as a hidden field, so there's nothing new to do. On the Action that catches the form, call isTokenValid(request); If the token is not valid, branch to an error page. Otherwise, call resetToken(). If another copy of the form tries to submit it again, now isTokenValid() will return false. The token is a random number that gets stored in the user's session. A second copy is suppose to be stored in the request. If the session and request tokens are missing or is different, then the transaction is out of synch. saveToken() puts it into the request. The Struts tags write it out as a hidden field or parameter. resetToken() clears it from the request. Loop closed. The Core J2EE Patterns book covers this and a ton of other handy strategies and patterns. Highly recommended.

more than one click in submit button
I'm developing an application, and I found an error, which is: I have a JSP page with a form, and if the user clicks in the submit button twice (one click immediatly after the first one) the Action is executed twice. What's the best practice to treat this behavior ? I mean, only one action should be executed. How do I handle this ?

who do I make my app secure ?
Hi guys, I have a question. I have an application which has a login page. Once the user puts this login and password and click submit, the data is transfered to FormBean. My question is how can I make this data secure ? I mean, the data goes opened through the net. How can I encrypt it ? thanks Jefferson -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

off topic - ARGO UML - URGENT
Sorry about this question, but I really need some help here. How can I make a constructor using ARGO UML ? If I just add a method with the same name as the class, the tool puts a void ??

site hosting
Hi guys, A friend of mine and I are developing a new application using struts, but not for any company, just for ourselves. We are looking for some site hosting service, free ones.

Re: New Site
Yes, it took some time to come up totally! Jefferson Galbreath, Mark wrote: This is not very encouraging. At 6:30 AM EST on a T-1 I finally gave up when the page had not fully loaded after 3 minutes(!!). My personal experience with Struts (we are committed to it at this point for VoiceStream Global Wireless's new ecommerce sites) is that it slows processing and page deleivery considerably. Anyone else notice this?

set form int field
Hi guys, I'm having a problem with a bean int field. When the user clickes in the form, the cursor goes to the end of the text field. Then it types the value (let's say 3) and click in the submit button. What is happening is that the value (3) does not go to the bean field, instead, the bean field gets a 0. How can I do a trim in the form before the set is applied to the bean field ?

nested:image
Hi guys, I have a new problem.
I'm using a nested:iterate, and one bean attribute is a key to an image in my
properties file.
public class TeamBean {
private String team = team.brazil
...
}
in the properties file I have the following entries
team.brazil=Brazil
team.brazil.flag=brazil.gif
Now I need to insert the team name and its flag gif inside the nested:iterate
Does anybody know how do I do that ?
Thanks in advance

problem with arraylist and iterate
Hi all, I have the following problem: I have a bean User which has a hashtable attribute bets. The getBets method returns a Bet[] array. The Bet class has 6 attributes. In the bets.jsp page, I show in a table all the values from the Bet objects (using iterate), one row for each object, and two of these values from each object the user is able to edit. The bets.jsp page is ok, all the values are being displayed, and the user can edit the two fields for each row. My problem is when the user submit this bets.jsp. How can I get all the fields (two for each table row) in a Form bean ? I want that the FormBean to handle the submit is the BetsForm ? I implemented the BetsForm with a single attribute, an ArrayList called bets. How should I implement this BetsForm bean ? How can it receive all the fields from the bets.jsp page in the arraylist attribute ? Thanks in advance Jefferson
