Re: Validation - Require One of Multiple Fields

Re: Control Access
The documentation that comes with Struts and the examples actually show a great example of doing this. Basically there is a tag that you place at the top of each JSP page that checks to see if the user has an object in session (has logged in) and if not, redirects them to the login page. Hope this helps... mahesh kagitha wrote: Can any one please explain the following...

Saving form data
Is there any piece of functionality in Struts that I can take advantage of in order to save and restore form data entered by the user as the page is reloaded. For example I am displaying an html table that shows a paged view of the data. The user can click on page 1,2,3, etc. Clicking on these links reloads the SAME page, but with the next subset of data in the html table. The problem I am running into is that the page in question also has a form area where the user is supposed to fill in information and submit it. When the user clicks on the links to page through the table, the data they entered in the form fields is lost. In the past, I have made round trips to the server and submitted the form data, storing it in session to later be retrieved. I want a better approach now though. I was considering passing the form data in a querystring but am afraid I will hit its size limit. Any ideas as to how this can best be accomplished? -Joey - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem with empty file upload field
I do not think it does, although I have not tested it - I don't run Windows, sorry. However after reading other people's posts and the bug report from mozilla I would make an assumption that it does not. It would be interesting to hear back from anyone if they can state otherwise.

Re: Problem with empty file upload field
What mozilla is doing is not populating the necessary information to the server for the file upload when the user does not enter a file at all (not just failing to use a FormFile versus a String) . If you read the thread on the bug report I attached below this will become more clear Cynthia. Mozilla fixed this bug in order to be compatible with other browsers so this leads me to believe this behavior is not present in other browsers. I have not confirmed this though on IE, but Netscape is probably okay since it is Mozilla-based. As for a workaround, the best I got before I found that upgrading Mozilla fixed my problem, was to do client-side validation with JavaScript. In the end though this only ensured the user did specify a value for the file to upload. It did not ensure the file was valid, which BTW if the file is not valid you will get the same error :( If I had to write a more elegant workaround, I would look specifically for this error condition in an exception handler and return a more sophisticated error to the user if the did not enter a file or entered an invalid file (e.g. file does not exist in path specified). Good luck, let me know how it turns out! -Joey Cynthia Jeness wrote: Since I am running Mozilla 0.99, this may be the cause of the problem; however, we have little control over what browsers our customers choose to run. If Mozilla does not send back a file name, then that piece of information can be missing from my error message to the client. However, the error itself needs to be handled more gracefully. It would be daunting to the normal user to be presented with an invalid argument exception on bean populate and a stack trace. I have tried to understand where the error occurs. It seems to me that when Mozilla cannot process the filename that the user has entered, the file name is sent back as part of the request parameter stream and the commons populate routine is handling it like a string. It fails because it cannot find a write method for the parameter which accepts a String. I have tried providing a setter which accepts an Object; however, then the file transfer does not occur when a proper file name is supplied. I have also tried two different setters -- one with a String and one with the FormFile. This also does not work. So, in short, are there any suggestions for a workaround or plans to handle the error situation more gracefully in Struts or the commons-beanutils routines? Of course, if Mozilla 0.99 is the only browser that has this problem and Netscape 4.6+ or IE work correctly along with later versions of Mozilla, then a workaround may not be as necessary.

Re: how to Validate DATE?

Re: Problem with empty file upload field
Wow, surprised you never got an error!?! I am using struts 1.1b3 and recieve an IllegalArgumentException (argument type mismatch) from BeanUtils.populate when the user does not specify a file to upload (leaves form entry blank). I verified the following: - I have my form's enctype set to multipart/form-data - I have my form bean's property for the file to upload declared as type FormFile - Even though my struts-config says that my form bean should validate (validate=true), the validate() method is never called. The exception comes before the validate() method gets a change to be invoked. This leads me to assume that it is the binding of the html form values to the form bean that is the culprit... I have also verified this behavior under struts 1.02. If you do not receive this error, then can you tell me what version of struts you are running? Thanks!!!

Re: Problem with empty file upload field
Thanks Claude,
I was beginning to think this might be the case. I guess it is time to
brush up on my javascript :)
Hopefully by the time I get the client side validation done, someone
will come up with a solution to get the server side validation for the
html:file to work. Apparently it works for Jörg but I am not sure which
version of struts he is running...

Claude Betancourt wrote:
Joey,
Since you need to cover your butt on both sides, client and server, do a
simple javascript validation on the form as it is being submitted to make
sure something was entered in the file input field.
function validateUploadForm(theForm) {
if (theForm.myFile.value==) {
alert(Please select a file to upload from your workstation by clicking
the Browse button.);
theForm.myFile.focus();
return false;
}
}
After that, your action should be smart enough to check for any of the
obvious file (FileInputStream) properties, like contentType, fileName or
fileSize (to be 0). Look at the API for java.io.FileInputStream
