Unable to read pdf : "org_apache_pdfbox_util" is not getting listed under JavaClasses

Hi,

I am trying to call

textStripperObj = JavaClasses.org_apache_pdfbox_util.PDFTextStripper.newInstance();

but 'org_apache_pdfbox_util' is not getting listed under JavaClasses

I followed all the steps listed here:

Can you please let me know as how to overcome this problem?
