Dmitrii, It would also be good to skim the developer guide for the original JUMP program. Some of the material is outdated, but a great deal of it still applies to OpenJUMP:
www.vividsolutions.com/JUMP/bin/JUMP%20Developer%20Guide.pdf If you are eager to get started with the code we will be working with the Plug-In Interface and AbstractPlugIn class from OpenJUMP. Also the LineString class from JTS.
