Rucaja (Rust calls Java)

Calling Java code from Rust via JNI.

Status

Things should work.

A more complete example is kud1ing/tinkerpop-rs which uses Rucaja to call Apache TinkerPop.

Creating a flat Java wrapper class and producing a fat JAR with all the dependencies reduces the Rust interface code.

Platforms

The code is tested on Linux and macOS. Your platform might need adjustments in build.rs.

Mac

Trying to run may give:

dyld: Library not loaded: @rpath/libjvm.dylib
  Referenced from: ./target/debug/rucaja
  Reason: image not found
Abort trap: 6

this might require something like:

sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
