  • JDiskExplorer returns "Error Initializing Parser" message on loading ?
    Make sure that custom HTTP error pages are not enabled for the web folder where you've installed JDiskExplorer. JDiskExplorer tries to load an internal parser matching to your FTP system (returned by FTP SYST command). For instance, for UNIX Type: L8, it tries to load http://yourserver.com/path/UNIX%20Type:%20L8.class. Your server must return HTTP 404. With custom HTTP error pages, it returns HTTP 200 that generates the parser error.
HTTP related
  • How to setup JDiskExplorer for HTTP transfers ?
    You need a server-side script implementing JDiskExplorer commands to list folders, make folder, rename and delete files. We provide three samples:
    - One that works with JSPUpload script. You have to use explorer.jsp from server-side/jsp/ folder and add <%@ include file="explorer.jsp" %> in process.jsp (see readme.txt from JDiskExplorer package).
    - Others that work with PHP and CFM samples scripts available in add-ons section. You have to use explorer.php from server-side/php/ folder and add include "explorer.php"; in process.php (see readme.txt from JDiskExplorer package).
  • Does JDiskExplorer support SSL ?
    Yes, both HTTPS and FTPS. Just modify url parameter (with https://yourserver, or ftps://yourserver) to make it works.
  • How to prompt end-user for FTP login/password ?
    First, enable authentication parameter such as :
    <PARAM NAME="authentication" VALUE="auto">
    Second, remove all username and password parameters. End-user will be prompted on first transfer action (upload, download, refresh, ...).
    If you want to prompt end-user on applet loading (before first transfer) then you have fill in username parameter with any value (e.g. anonymous) and an empty password such as :
    <PARAM NAME="username" VALUE="anonymous">
    <PARAM NAME="password" VALUE="">
    You have a sample image of the prompt on the right.
    Three attempts are allowed.
