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.
Geo Bookmark is a simple widget that adds a bookmark with the current time and geographical position to the home screen. The interface is kept minimal to allow operation in situations that do not permit extensive interaction with the phone (e.g. while driving a car). Bookmarks are color coded. Blue icons represent exact locations, red icons mean that the widget could not get a GPS fix within 40 seconds and therefore recorded the last known location (which may or may not have been determined by means other than GPS). In order to view a bookmark, a suitable maps application needs to be installed (e.g. Google Maps or OSMAnd).
