G4ZFE Log Search Applet - FAQ

Known Problems

  1. The applet will not work behind a firewall or proxy server. The search will appear to work and then a message "Sorry .. <logname> not found" will be displayed. This indicates that a connection could not be made back to the server to download the log file.

Frequently Asked Questions

  1. I get an error "applet search can't start: class search not found"

    This error message appears on the Web browser's status screen. It means that the Log Search java applet could not be found on your web server. The search.class file must be in the same directory as your search HTML page (unless you have used the CODEBASE applet parameter). Also ensure that you transferred the search.class file in binary mode to your web server. Some web servers are case-sensitive so ensure that the search.class filename is of the correct case.

  2. When I search for a callsign the following is displayed:

    "Starting search
    Sorry .. <logname> not found!
    Search completed ... 0 QSOs found"

    This message is usually caused by the log files not being stored in the correct directory on the web server.

    e.g. the following applet parameter indicates where the files are on the server:
    <param name="URL1Name" value="http://www.myisp.co.uk/~g4zfe/logs/8Q7FE/">

    Using the above example opening the URL "http://www.myisp.co.uk/~g4zfe/logs/8Q7FE/G.TXT" should display all the stations beginning with "G" that were worked in the 8Q7FE expedition. If your web browser displays an error (e.g. File not found) that the data files have not been transferred correctly and this is the cause of the problem.

  3. When I search for a callsign the following is displayed:

    Starting search
    Error whilst reading contest log file..
    Search completed ... 0 QSOs found

    This message is caused by incorrectly formatted log files:

    Check this by opening a data file as shown above and check that the line is similar to the example above. If not then you have probably found a bug in the sortlog program used to generate the data files. Please let me know so that I can fix it!
