java - PDFJET Does Not Work For En Empty Constructor -

i want use pdfjet google app engine project.

i downloaded java jar ppdfjet home page.

i followed example given in stack-overflow example , examples given in home page. examples uses empty constructor: pdf pdf=new pdf();. when try use it, says constructor pdf() undefined, further more method shown not work:

pdf.wrap(): undefined

pdf.save("example_03.pdf"): undefined

it looks examples on web page out of date. @ examples in zip download instead. simple example works me:

outputstream out = new fileoutputstream("test.pdf"); pdf pdf = new pdf(out); page page = new page(pdf, letter.portrait); pdf.flush(); out.close();
