Re: DownloadAction and concurrent threads
I see no reason why the DownloadAction would be programmed to synchronize against anything, especially for the whole download, that would be a real showstopper! If you don't use instance variables, and only read from a database (with a connection for each download) or a filesystem, you wouldn't need to synchronize either. Oliver Meyn wrote: Hi all, My app needs to allow downloads of relatively large files (10MB). Because Struts can/will reuse Actions for different threads, I'm worried that when multiple requests attempt to download these big files that a single BigFileDownloadAction will block until a download is complete thereby slowing all downloads (effectively making them serial).

Re: FormFile arrays
You are right about the jakarta commons fileupload and struts, you can't use commons fileupload in an action, because struts have already taken care of the multi-part parsing. You do have the option to make a servlet and commons fileupload, where you will have total control of the form data. I'm not certain about your way of making the files go into an array. Is that the way to do it with for example html:text? One would expect it to work in a similar fashion. http://www.jguru.com/faq/view.jsp?EID=915898 This link suggests that you use the same name all over again for each entry, like notworkingfile, notworkingfile, and so on... Jeremiah Johnson skrev: I would like to upload multiple files on a single web page by having multiple html:file elements. The exact number of these are different depending on the user who is using the application. So I want to store this in an array (FormFile[]) in order to have N number of files uploaded. When I try to use html:file/ tags in an iterate loop (with indexed=true) I get an error about requiring property attribute. There's isn't a good way of doing that so I just rendered the the HTML with scriplets. It looks something like: input type=file name=workingfile/ input type=file name=notworkingfile[0]/ input type=file name=notworkingfile[1]/ input type=file name=notworkingfile[2]/ The form has getters and setters for workingfile (of type FormFile) and notworkingfile ( of type FormFile[] that is 3 elements). workingfile is assigned an instantied object however each element of notworkingfile[] is null after submit. I then attempted to use commons-fileupload-1.1.1 in a struts action (struts 1.2.9) to read the uploaded data but it does not recognize that any files are being uploaded (including workingfile). I tried this code: List items = new ServletFileUpload( new DiskFileItemFactory()).parseRequest(request); items results in an empty collection (but not null). I've read that you can not use commons-fileupload in a struts action which may be why that doesn't work. Anyone know how to have variable number of file upload boxes? I know I could have properties for each file (file1,file2,file3 and so on) instead of array but I'd rather not implement it that way. Thanks!

How do I get the original RequestURI?
Hi, I want to do something like this: 1. User enters http://localhost/appname/welcome.do 2. PlaceAction forwards to list.do 3. In ListAction, I want to retrieve the URL the user entered /appname/welcome.do. The problem: when I run getRequestURI in the ListAction, all I get is /appname/list.do.

You are absolutely right about that, I could modify PlaceAction to save the URL somewhere.

Re: How do I get the original RequestURI?
What? I'm sorry, but I'm not asking about how to assemble an URL. I want to retrieve the original URL sent by the browser in the request. The request.getRequestURL() is wrapped and modified with each forward, and I want the first, by the browser, requested URL. Since so many seem to misunderstand me: 1. User inputs http://localhost/appname/input.do; in browser. (Mapped to InputAction) 2. InputAction's request.getRequestURL() is http://localhost/appname/input.do; 3. InputAction forward to OtherAction. 4. The OtherAction's request.getRequestURL() is http://localhost/appname/other.do;. -- THIS ISN'T WHAT I WANT.

Re: How do I get the original RequestURI?
He, I'm using Struts 1.2.7, and it's not there. :( Too bad for me. However, I think my problem must have been solved in some way, because what I'm trying to do isn't that remarkable. Some actions require the user to be logged in. I want to direct them to a login screen. When they successfully logged in, I want to return to where they came from. Is the only option to *redirect* to the login action and use the HTTP Referer-header to save where they came from? (Or send the returnurl as a GET-parameter to the login action) I guess action chaining is kind of evil. Hey, it's not like there is any actual, factual documentation about struts out there waiting for me to find it? I'm having a very hard time finding any hints how to accomplish things. Adam J Samere skrev: 1.2 does not have this behavior. You could either use a filter as I mentioned, or to stay within the struts framework either create a common base Action subclass, or subclass RequestProcessor or ActionMapping to add the desired functionality. Either way would be a trivial task. I agree with Don, action chaining is bad! :) Don Brown wrote: Well, first of all, action chaing is bad ;), but second, Struts 1.3 at least, and perhaps 1.2 automatically saves the original request uri for you.

Re: How do I get the original RequestURI?
I got it working know, with no action chaining, and with redirects. The reason why I'm not using roles and J2EE security is because I haven't been able to figure out it is meant to work, and I just thought it would be easier to do myself. Any tips on how to start with the standard security and how to make integrate it with struts would be appreciated, however. Adam J Samere skrev: You didn't mention what you were trying to do was login related. You *could* render the target (original) URL as an input parameter in the generated markup when redirecting to the login page. Is there a reason you can't use the standard J2EE security and login configuration? This does exactly what you are trying to do, and handles checking whether the user is logged in, has the correct roles etc. for you. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Well, I suppose you'll have to use some tricks to make it work.
div class=hidedivs
html:form ..
div class=workaround
html:text ../
divs with class or id attributes left unspecified
/div
/html:form
/div
And stylesheets:
div.hidedivs {
display:none
}
div.workaround div {
display:block;
}
Haven't tested it.
