The Big Faceless Java PDF Viewer is a Swing component that can display PDF documents. It is intended for developers who don't require the full API. The PDF Viewer can be installed as an applet, an application, via Java Web Start, or embedded in a Swing application. Printing, saving, text search, forms, digital signatures, and annotations are some of the many features available. The viewer can be tailored to include just the features you need, and is a cost-effective solution for those needing the features of Adobe Acrobat on a Java platform.
Hoplax is a power user tool to store bookmarks in text files and manage them efficiently. Bookmarks stored in Hoplax are easy to edit and search with normal Unix tools and editors. They are easy to synchronize with git/svn/darcs/etc. Bookmarks can be categorized easily into files, and you can choose to not synchronize a file to a computer, e.g. confidential company bookmarks to home computers. The filtering is smarter than the browser's location bar. Keyword bookmarks with multiple parameters and auto-completion are supported.
