Basic "Hello World" java console application that generates a PDF file.
Hello World (Java) sample is a basic Java console application that generates (using the novaPDF printer) one PDF file containing the text "Hello World from Java2!". It demonstrates the basic use of the INovaPDFOptions interface with j-Interop.
Note: To be able to use the samples you must install novaPDF SDK as samples work only with it. Download it here: nova PDF SDK.

What this sample does:
  • determines the active profile, makes a copy of it and names it "Test Java"
  • sets the new profile (Test Java) as active as well as some mandatory settings (e.g. the subject of the PDF)
  • generates a test PDF file
  • restores the original settings of the novaPDF printer driver.
“j-Interop is a Java Open Source library (under LGPL) that implements the DCOM wire protocol (MSRPC) to enable development of Pure, Bi-Directional, Non-Native Java applications which can inter-operate with any COM component.“ j-Interop can be found at <>

If you encounter problems or have questions on using j-Interop, visit their FAQ page. Also, to avoid the “Logon failure: unknown user name or bad password” error, configure DCOM for remote access (detailed here) and make sure your firewall is not turned on.
