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.
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.
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 interoperate with any COM component.“ j-Interop can be found at
http://www.j-interop.org/
Note
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.
