jtem is a collection of mostly mathematical tools and algorithms implemented in Java.
The libraries include a wide range from complex numbers to theta-functions, basic linear algebra and adaptive ODE solvers. jtem also provides you with some useful applications like JTerm, a swing component that roughly has the look and feel of a Unix shell window, and JDvi, a viewer for TeX's generic output format known as dvi, which comes as an application and as an applet to place dvi files on the web.
