Sometimes you want to add something to your menu, which some distributions make easy for you and others don't. Following an installation of Oracle Database I wanted to add SQL Developer to the menu, this is what I did:
Firstly I created a file in /usr/share/applications called "sqldeveloper.desktop" and then in the file I placed the following:
[Desktop Entry]
Version=1.0
Type=Application
Name=SQL Developer
Comment=Oracle SQL Developer GUI Utility
Exec=/apps/oracle/product/11.2.0/dbhome_1/sqldeveloper/sqldeveloper.sh
Icon=/apps/oracle/product/11.2.0/dbhome_1/sqldeveloper/icon.png
Categories=Application;Development;
MimeType=text/plain;
Encoding=UTF-8
X-Desktop-File-Install-Version=0.10
I did this as root by the way and it worked fine! Note that your exact paths might be different to mine.
