The Word OLE (Java) SDK sample is a basic Java console application that converts a MS Word document (in this sample the default location for the source document is C:\temp\test.doc) to PDF using Word OLE automation and j-Interop along with novaPDF.

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.

“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.
