    Question Jamba

    I am not very knowlegeble with Java. So back in the 90s I bought an applet development program called Jamba by Amitech and developed 30 or so games in java applets for kids. The games worked great for years.

    Jamba stopped working after xp came out and amitech was long gone by then.

    About a year ago the applets just stopped working and I get the following error in the sun console.

    Error reading JTF file: abcgetem.JTF
    http://www.allaboutstuff.com/kids_games/abcgetem.JTF

    Is there any way to determine what it is that the newer versions of java do not like

    any help would be appreciateded
    Thanks
    Brian

    Default

    Java Code:
    Error reading JTF file: shapes1.JTF
    http://www.allaboutstuff.com/kids_games/shapes1.JTF
    Error reading JTF file: Towers.JTF
    http://www.allaboutstuff.com/kids_games/Towers.JTF
    Error reading JTF file: abcgetem.JTF
    http://www.allaboutstuff.com/kids_games/abcgetem.JTF
    I'm unable to find your file "abcgetem.JTF"
    Java Code:
      <applet code="Jamba/player/JambaPlayer.class" width="540" height="350">
      <param name="fps" value="15">
      <param name="filename" value="abcgetem.JTF">
    Are they still there?
    Is there any way to determine what it is that the newer versions of java do not like
    Probably. Access to a source (.java) file and its corresponding data (filename) file would help, eg, JambaPlayer.java and abcgetem.JTF (in plain text).

    Default jtf file included

    Yes it is still at that location

    http://www.allaboutstuff.com/Kids_Games/abcgetem.JTF

    I have attached a zip file with the contents of the jtf file included in a text file within the zip.

    All of the class files are in the folder Kids_Games/Jamba/player there are no files ending .java. I can zip the class files too if it helps.

    Thanks for your help.

    Default class file included

    I thought that the JambaPlayer.class might also be helpful so I included it as a text in a zip as well.

    Thanks again

    Talking Answering my own question

    First let me say thanks for your help.

    Maybe someone else out there is having this problem and this will help them too.

    Apparrently The file extension .JTF is now being used by other programs for images.

    I think the current versions of Java are looking for images hence the file reading error.

    I changed the file extension for the .JTF file to .txt and now the applet works fine.

    Even IE won't open the JTF file because it thinks it is looking for an image too but it will find the txt file.

    I think when Hardwired said "I'm unable to find your file "abcgetem.JTF"" I got on the the right track to solving the problem.

    Some times banging your head against the wall does work.

    Thanks again
