parity-clib: Java example
|
|
||||||
===================================
|
|
||||||
|
|
||||||
An example Java application to demonstrate how to use `jni` bindings to parity-ethereum. Note, that the example is built in debug-mode to reduce the build time. If you want to use it in real project use release-mode instead to facilitate all compiler optimizations.
|
|
||||||
|
|
||||||
## How to compile and run
|
|
||||||
|
|
||||||
1. Make sure you have installed [JDK](https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
|
|
||||||
2. Run `run.sh`
