I'm absolutely new to ubuntu. I'm going to program java using eclipse, so I extracted file "eclipse-standard-kepler-SR1-linux-gtk-x86_64.tar.gz" in some folder, and tried to run "eclipse" in the extracted folder. But it showed the following message:

"Could not display eclipse.    There is no application installed for
'executable' files. Do you want to search for an application to open
this file?"

I clicked "yes" and installed "pypar2" as its recommendation. But still I cannot execute this file. What should I do to start using eclipse? Can anyone please help me?

you have a variable called $PATH in your bash. any executable that in in one of the folders displayed by

$ echo $PATH

can be executed by giving the name of the executable in any working directory:

$ eclipse

but if your eclipse is not in one of the paths in $PATH you either need to go to the directory where eclipse is and use

$ ./eclipse

or use the full path: e.g.

$ /opt/eclipse/eclipse

i usually create a launcher that i can drag to the bar on the left:

1) create a file with the contents (adapt the paths to your needs):

[Desktop Entry]
Name=eclipse 4.5 mars
Comment=
Exec=/opt/eclipse/eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
StartupNotify=true

  1. make the file executable (e.g. with nautlius)

  2. drag and drop the file (again, using nautilus) to the launcher bar.
