Java bindings for libwpd

Note	This page is here only for historical reasons. You probably want to have a look at the opened code.

1. What’s libwpd-java?

libwpd-java is an attempt to work with libwpd in Java.

2. Why is it good?

If you have a Java application and you want to work with WordPerfect (tm) documents, you’ll find it useful.
It binds libwpd’s custom types to native Java types, like WPXPropertyList to java.util.LinkedHashMap<String,String>.

3. How does it work?

The code at the moment is not yet public. Here are my plans:

I wait for somebody who really needs this.
I want to get paid for my work. If you, or your company are interested in funding, please contact me.
To be legal and respect GPL, I want to publish the work under GPL as well, and submit the code for inclusion in the libwpd project.

4. Example

As an example, you can see how the Java version of the original wpd2raw C++ program looks like, using libwpd-java:
