working now :)

Re: If tag expression problem
Hi,
I tried but still no luck.
Here is the code for generating the pages array inside the action:
private String pages[];
// inside execute...
pageSize = 15;
int numberCards = this.retrieveNumberCards(db,(String)user);
this.pages = new String[(numberCards/this.pageSize)+1];
for (int i = 0; i<(numberCards/this.pageSize)+1; i++) this.pages[i] =
Integer.toString(i);
// getter and setters...
public String[] getPages()
{
return this.pages;
}
public void setPages(String[] pages)
{
this.pages = pages;
}

If tag expression problem
Hi, I have the following code that displays a list of page numbers that all have links except for the current page (defined by the request parameter 'page'): However this doesn't work and the if condition is alway false. I tried outputting the value of #it in each itteration and got the correct values (numbers 1-5) and done the same with the #parameters['page'] and got the number 2. I also tried substituting the if tag for and this worked!! The pages array in the action was an array of ints so I thought maybe there is a type mismatch since the request parameter would be a string so I tried converting the array to strings but still no luck. Is this if tag valid? Can anyone tell me where im going wrong?

Re: Logging not working
The tag worked, thanks that will come in handy. I would still like to get errors reporting in the logs, any got any ideas?

Logging not working
Hi, I can't seem to get any errors to appear when struts goes wrong (action trying to set/get an attribute that doesn't exist etc). I have the commons-logging-1.1.jar file in my /WEB-INF/lib folder and have the line in my struts.xml file. Despite this I have never seen an error in my log files. Is there something im missing here? Would the errors appear in the same log as servlet exceptions (/logs/localhost.-xx-xx.log)?

Re: Problem with required validator
Thanks for the replies. I figured out what the problem was. My model in the action class is a member variable called user, so I needed to change the name of my form fields and validator fields to user.userName instead of just userName. 2010/10/5 Raymond He : > You can debug your app,and step in the required validator > class'validation method.

Problem with required validator
Hi, I have a xml validator for my user login action which requires values for both the userName and password fields. However when submit the form with these fields populated I still get the same "Username is required" and "Password is required" messages. Am I right in thinking that the "required" validator is triggered if no value is supplied for the field? If thats the case why would it be triggered when I supply values for those fields? Here is the validation xml file: http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd";> Username is required. Password is required.

Re: How to structure a struts2 application

How to structure a struts2 application
Hi, I have just started learning struts2 and was wondering what is the best way to structure my application. I was planning on creating one ActionSupport class to deal with all user action (creating, editing, login etc). This would have a method for each type of action (create(), login() etc) and a mapping with a wildcard like this: However im not sure if this is the best way of doing things because all of the user actions would share the same validate method, and each different type of action would need different validation. I was thinking of maybe putting a switch in the validate method to do different validation depending on which action has been called, or perhaps just having different action classes for each type of user action. Do either of these approaches sound sensible? Or am I missing an easier way to go about grouping up all the user actions? Regards Darren
