.desktop file running sh script "There was an error launching the application."

I have a .desktop file:

[Desktop Entry]
Type=Application
Terminal=true
Name=RunMe
Exec=run.sh

When I double click the .desktop file, I get There was an error launching the application.

my run.sh is:

#!/bin/sh
xulrunner-sdk/bin/xulrunner-stub --app xulrunner-sdk/bin/application.ini 2>~log.log

Double clicking on run.sh and clicking run runs the application fine. Both run.sh and my .desktop are executable.

What do I need to change in my desktop file to make this work?

To figure out what exactly is the error as you asked

What do I need to change in my desktop file to make this work?

After a lot of research, I found that you can indeed validate your desktop file with this command

desktop-file-validate your-file-here.desktop

This was the hidden command I was trying to find since hours. This, Saved my day :-)

This command will show you warning and errors wherever you have gone wrong. Credits : ubuntuforums

%k is the desktop file path, use it with sh to relative .desktop:

Change current working directory (pwd), Then run.sh & commands inside all will run from there:

[Desktop Entry]
Type=Application
Terminal=true
Name=Run Me
Exec=sh -c "cd `dirname %k`; run.sh"

Otherwise, passing it as parameter to run.sh and use it explicitly when you need inside run.sh:

run.desktop

    [Desktop Entry]
    Type=Application
    Terminal=true
    Name=Run Me
    Exec=sh -c "`dirname %k`/run.sh `dirname %k`"

run.sh

    #!/bin/sh
    $1/xulrunner-sdk/bin/xulrunner-stub --app $1/xulrunner-sdk/bin/application.ini 2>$1/~log.log

Reference: How can I set the 'Path' variable in a .desktop file to be relative to the location where the desktop file is located?
