Using Struts 2: when will the .tmp file – that gets created after uploading

  • 0

  1. Using Struts 2: when will the .tmp file – that gets created after uploading a file – be deleted?

  2. How can you customize when the .tmp file should be deleted? Do you have to create a copy of it?

Please don’t be shy to give some code 🙂

    1. This depends on which version of S2 you’re talking about.

    • S2.2.1 and prior: the file upload interceptor deleted temp files.
    • S2.2.3 and above: the filter dispatchers start the deletion process, changed due to WW-3490.

    2. Assuming you’re using a recent version, it might be possible to inject a tweaked Dispatcher, although it’s not immediately obvious how–if it is, that’s the easiest change at the core level.

    The easiest approach from a practical standpoint is to copy files in the action, which is also pretty fast on any reasonable file system.
