Question

Answer 1

A quick Google search on java dxf yields the ycad library. I have never used it, I don't know how well it works.

Answer 2

The reading of an AutoCAD DXF file is not a trivial task. The contained entities can be affected by the coordinate systems, the blocks can be hierarchycal, etc. When I wrote my DXF importer, I read the file sequentialy, built a DXF DOM and then converted it into my own format. You can find the document specification here:
