~Found kind of here, still need help with calling vb [L=http://www.javaworld.com/javaworld/javatips/jw-javatip17.html]http://www.javaworld.com/javaworld/javatips/jw-javatip17.html[/L]
Convert PDF to text from Java
~Found on sourceforge.net - pdfbox

I am working on a project and we are doing the feasibility analysis of certain features...so that's why I need the open source.
