Java and PDFs
I thought it was interesting to see that Adobe have released their own PDF API in Java. Sure, it’s only a viewer Javabean, and it’s not open source. However, it’s free to use and it means you can integrate PDF viewing and printing into your applications.
Java.net published an excellent tutorial on making use of this component. When combined with other libraries, like iText - a Java API for PDF generation - then you can have pretty good setup for reading/writing portable documents.
