Java Examples |
||||
====== |
||||
## ZeroTier with Java via JNI |
||||
*** |
||||
|
||||
`make shared_jni_lib SDK_JNI=1 SDK_IPV4=1` |
||||
To get this example project to work, do the following: |
||||
|
||||
Uses API described in [api/java/README.md] |
||||
- Copy `src/ZeroTier.java` into `your_project/src/zerotier` |
||||
- Copy `src/Address.java` into `your_project/src/zerotier` |
||||
- Copy `libzt.jnilib` or `libzt.so` from `build/` into `your_project/lib` |
||||
- From libzt main directory, build shared library: `make shared_jni_lib` |
||||
- Copy the resultant dynamic library (`*.so` or `*.dylib`) from `build/` to this current directory |
||||
- Change to this directory and `make example_java_app` |
||||
- Run: `java -cp "." ExampleApp` |
||||
|
||||
|
||||
Notes: |
||||
|
||||
Upon execution, it will load the libzt dynamic library via the `loadLibrary` method and begin generating an identity. |
