Download the jLog application for Linux

The installer and optional files are available under these License conditions:

*) These files are only needed if a Radio or Keyer is to be connected via a serial communications port. New, improved RXTX version 2.1-7.

Instructions

1. Unless already installed, please install the Java Runtime Environment before installing the jLog application.
    
2. Log in as the preferred user and download the installer program that corresponds to the selected version of jLog.
    
3. Make sure that the logged in user can reach the Java (JRE) previously installed by opening a Terminal window ("shell") and typing:
   
   $ echo $PATH
   
   Inspect the output. If Java is not found in the PATH, please enter (assuming that the Java JRE was placed in: '/usr/java/', substitute if different):
    

   $ PATH=$PATH:/usr/java/j2re1.6.0_04/bin; export PATH
   $ echo $PATH
   
   Please verify that Java is found in the PATH by re-entering 'echo $PATH'

4. Start the installation by typing:
   
   $ cd  <the directory where you placed the installer>
   $ sh ./install.bin
   
   The next steps are only necessary if you are going to connect a radio or keyer and you have not already installed these files when installing Java.
    
5. Download 'RXTXcomm.jar' and install it in the 'lib/ext' folder of the Java VM (e.g. for RH9 with Sun's Java 1.6.0_04: '/usr/java/j2re1.6.0_04/lib/ext').
    
6. If you are upgrading from V 3.x or V4 Beta 2 (i.e. from an older version of RXTX), please remove the file 'librxtxSerial-2.1-x.so' in the '/lib/386' folder (or equivalent).
    
7. Please download 'librxtxSerial.so' and install it in the 'lib/i386' folder of the Java VM (e.g. for RH9 or FC4 with Sun's Java 1.6.0_04 it will be '/usr/java/j2re1.6.0_04/lib/ext'). If the 'lib/i386' folder is nonexistent, place it in 'bin' or another Java VM folder containing '.so' files.
    
8. Important: Log in as root and add your jLog <user> to the group owning the '/var/lock' directory and to the group owning the serial port (e.g. /dev/ttyS0) to be used. This would typically (e.g. Red Hat 9) be users 'lock' and 'uucp' respectively. Try running jLog as root if you experience problems.
    
9. To increase log capacity beyond 30000 entries per file, you must change the Java VM properties.
    
10. Note that the default UTF-8 environment in  SuSE V 9+ must be changed to e.g. ISO-8859-1. See changing charset.
