After a research, i discovered that pentaho kettle community edition is under LGPL license(free and open source under appache), so i want to know :

1)--can the LGPL library be used in a commercial application that will be a console (web app or site on server appache) which execute jobs and transformations from a remote server (carte) and visualize errors and reports, 2)--what are the implications of (statically linking the library to the application)and (dynamically linking the library with the application )
and what should i chose.
