We were looking for a configurable java upload applet with source code for our file exchange service, Pipeline eXchange (www.pipelinexi.com), and came across Hermes Java File Uploader. We were able to quickly integrate the uploader into our service. The functionality is rich and the support is superb.
Your web/ftp server might be down or you made a typo in the action param. To make sure that this is not Hermes related problems, try copy pasting ftp/http url into your ftp client/browser.
Probably your webserver is configured to accept POST request of a certain size
and bigger files are over this limit. That's how some webservers protect its
users from flodding.
For details you need to consult your webserver producer's documentation.
Usually this means that jvm cannot access jar file, so please check that path in either archive param tag and archive attribute of applet tag are fine. Than restart your browser (refreshing page won't help since jvm has cached results of first request/response).
There seems to be some kind of extra privilege check on local file system that's why FF prevent's from using swing elements as drop target. Copy all files to your webserver (or access them through your localhost) and everything should work fine.
Form sent succesfully. We'll contact you shortly. Thank you!
