Question

Clicking on a .jxe file produced an exception: "unknown file type, bla bla bla..."
How can I install J9 on my Pocket PC and associate my .jxe files with it? This QA is translated from CodePPC.com.

Answer

  1. Download the PalmTweak utility

    from http://tillanosoft.com/anonymous_ftp/pub/ce/ptweak42e.zip

    In spite of its name, this zip contains all the CAB of each OS (MIPS, ARM, SH3). This tool makes it possible to associate a file extension with a program (as well as in Windows).

  2. Install it

    • Copy the CAB file in \windows\Start Menu\Programs
    • Click on it, it will be installed.

  3. Use it

    Start -> Parameters -> System -> PalmTweak

  4. Install the exe and the DLL of J9 in a PPC folder

    (for example \My Documents\ive-13\)

  5. Create a folder, in which you will store all your jxe programs

    (For example, \Windows\Start Menu\Programs\JXE)

  6. Launch PalmTweak

    (A corresponding doc can be found on http://tillanosoft.com/ce/ptweak.html)

  7. Copy a classes.zip file to your J9 folder (for example \My Documents\J9)

    for example, you can use that of jclCore.

  8. Add another record into the extensions list.

    Add a jxe record with the main executable application: " \My Documents\j9\j9.exe " " - bp:\My Documents\j9\classes.zip " " - jxe:%1 "
    Make sure to include the quotation marks.

    You can easily change the name, description and icon associated with the extension. Click Ok; the record is added.

From now on simple clicking on a .jxe file launches J9 and your program.
