This error typically appears when any another application is using
default port 8080.

Solving:

1. Stop eXo platform via stop_eXo.bat

2. Open file <your_eXo_files>\conf\server.xml
for example on my PC C:\eXo\conf\server.xml

3. Change default port from 8080  to 8081

4. Start eXo platform via start_eXo.bat

eXo platform: Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

Trabla: starting eXo platform via  start_eXo.bat
- error in cmd:

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

Solving:

To fix this error we need to create new environment variable
with name JRE_HOME
and value - path to JRE - java runtime environment

1. Open Control Panel -> System

2. Click "Advance system settings"
then click "Environment Variables"
then click "New"

3. Create new environment variable
JRE_HOME with value - path to JRE - java runtime environment
( e.g. on pc - C:\Program Files\Java\jre1.8.0_92 ) and press ok

ATTENTION: if you have opened windows command promt ( cmd )
- you should restart it to new environment variable take effect !!!

eXo platform: CATALINA_HOME environment variable is not defined correctly

Trabla: starting eXo platform via  start_eXo.bat
- error in cmd:

The CATALINA_HOME environment variable is not defined correctly
This environment variable is needed to run this program

Solving:

To fix this error we need to create new environment variable
with name CATALINA_HOME
and value - path to eXo files folder

1. Open Control Panel -> System

2. Click "Advance system settings"
then click "Environment Variables"
then click "New"

3. Create new environment variable
CATALINA_HOME with value - path to eXo platform files
( e.g. on pc - C:/eXo ) and press ok

ATTENTION: if you have opened windows command promt ( cmd )
- you should restart it to new environment variable take effect !!!

Windows & CMD: fc command - text diff (compare) files

Trabla: Windows & CMD: fc command - text diff (compare) files

Solving:

1. File 1 - test1.php
<?php

echo 'test1';
echo 'bla';
echo 'zzz';
echo 'return1';
echo 'lalala';

?>

2. File 2 - test2.php

<?php

echo 'test2';
echo 'bla';
echo 'zzz';
echo 'return2';

?>

3. Use fc command
fc /N /A test1.php test2.php



Comparing files test1.php and TEST2.PHP
***** test1.php
    2:
    3:  echo 'test1';
    4:  echo 'bla';
***** TEST2.PHP
    2:
    3:  echo 'test2';
    4:  echo 'bla';
*****

***** test1.php
    5:  echo 'zzz';
...
    8:
***** TEST2.PHP
    5:  echo 'zzz';
    6:  echo 'return2';
    7:
*****

4. fc command command help
fc /?
Compares two files or sets of files and displays the differences between
them

FC [/A] [/C] [/L] [/LBn] [/N] [/OFF[LINE]] [/T] [/U] [/W] [/nnnn]
   [drive1:][path1]filename1 [drive2:][path2]filename2
FC /B [drive1:][path1]filename1 [drive2:][path2]filename2

  /A         Displays only first and last lines for each set of differences.
  /B         Performs a binary comparison.
  /C         Disregards the case of letters.
  /L         Compares files as ASCII text.
  /LBn       Sets the maximum consecutive mismatches to the specified
             number of lines.
  /N         Displays the line numbers on an ASCII comparison.
  /OFF[LINE] Do not skip files with offline attribute set.
  /T         Does not expand tabs to spaces.
  /U         Compare files as UNICODE text files.
  /W         Compresses white space (tabs and spaces) for comparison.
  /nnnn      Specifies the number of consecutive lines that must match
             after a mismatch.
  [drive1:][path1]filename1
             Specifies the first file or set of files to compare.
  [drive2:][path2]filename2
             Specifies the second file or set of files to compare.

ffmpeg & cmd: convert WAV to MP3 in Win7 using FFmpeg

Trabla: ffmpeg & cmd - convert WAV to MP3 in Win7 using FFmpeg

Solving:

1. Install FFmpeg for Windows
https://visvis.googlecode.com/files/ffmpeg-win32-setup.exe

2. Create Folder Structure & files

C:\WAV_to_MP3
C:\WAV_to_MP3\WAV
C:\WAV_to_MP3\MP3
C:\WAV_to_MP3\WAV_to_MP3.bat

3. Place WAV files into folder C:\WAV_to_MP3\WAV

4. Edit file  C:\WAV_to_MP3\WAV_to_MP3.bat - type following command line script + Save

SET PATH=%PATH%;C:\Program Files (x86)\ffmpeg
for %%f in (C:\WAV_to_MP3\WAV\*.wav) do ffmpeg -i %%f -f mp3 C:\WAV_to_MP3\MP3\%%~nf.mp3

where
C:\Program Files (x86)\ffmpeg - location folder of  ffmpeg.exe file

for %%f in (C:\WAV_to_MP3\WAV\*.wav) do  - means foreach file in folder C:\WAV_to_MP3\WAV\  with any name but extension .wav execute command after word "do"

ffmpeg -i %%f -f mp3 C:\WAV_to_MP3\MP3\%%~nf.mp3  - ffmpeg conversion command
%%f - input file name ( full path )
%%~nf - only file name without path and extension


5. Run C:\WAV_to_MP3\WAV_to_MP3.bat in cmd.exe
