You found no examples because at the moment we don't generate Java bindings from the DFDL schemas. We'll try to squeeze the Java bindings in M2 since it was already
requested. In the meantime, I pushed an
example to my GitHub account showing how to (a) generate the Java bindings with XJC and (b) turn a Java binding object into EDIFACT. The
v2.0 branch holds the latest docs though they haven't yet been published to the Smooks website (2.0.0-M1 docs are
tagged). As for an estimate, we'll need to discuss it internally but I reckon that it's going to be by the end of this year when we release Smooks 2.
