I found an interesting platform problem with Stripes multi file uploads on Windows vs. Linux. I used the below document to implement multi-file uploads.
http://www.stripesframework.org/display/stripes/File+Uploads Using an index set of file uploads, such as: <stripes:file id="file_upload[0]" name="file_upload[0]" /> <stripes:file id="file_upload[1]" name="file_upload[1]" /> On both Windows (Windows 7) and Linux (Redhat Enterprise 5.5), the code works perfectly, but with one specific exception: On Linux, if the user uploads the exact same file for two or more "file_upload[x]" (the same file from his hard drive, such as c:\pictures\kittens_and_yarn.jpg for each upload), file_upload[n] is processed without a problem, but file_upload[m] and onwards gets a "file not found" exception for that one specific identical file upload. On Windows, every file_upload[x] is processed perfectly. My guess is what's going on is the underlying system is handling temporary files differently. I think Windows is creating a separate temporary file for each upload, while Linux is creating temporary filenames that is being overwritten with each subsequent file_upload[x] with an identical filename, and deleting/moving the single temporary file the first time it's processed. It's likely not a Stripes problem and Stripes probably has no control over how these temporary files work on different platforms, but it was causing a "yes it works / no it doesn't" argument with QA for a few days before I thought maybe I should check how it's working on the QA environment. QA and production runs on Linux, the developers are stuck with Windows (I know, I know). Anyway I hope this helps some other developer who runs into this problem. I'm not really sure how to handle this, so I'm thinking that probably what I will do is capture the filename/filepath of everything being uploaded, and if any of them are identical, to process that file input stream exactly once, and provide copies of this single file when requested. If someone has a better way I'd be very glad to hear how you handled this. Thanks again! -Derrick Karl Kirch wrote: > > Yep it was another js issue.
