This question already has an answer here:
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?
