-## Java
-
-At the time of this writing, versions of each plugins and tools are as
-following:
-
-- ProtocolBuffer: 3.3.0
-- grpc-java: 1.4.0
-- java: 1.8.0_131
-
-In proceeding with the following procedure, please substitute versions to the
-latest.
-
-### Install JDK
-
-We need to install JDK and we use Oracle JDK8 in this example.
-
-```bash
-$ sudo add-apt-repository ppa:webupd8team/java
-$ sudo apt-get update
-$ sudo apt-get install oracle-java8-installer
-$ java -version
-java version "1.8.0_131"
-Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
-Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
-$ echo "export JAVA_HOME=/usr/lib/jvm/java-8-oracle" >> ~/.bashrc
-$ source ~/.bashrc
-```
-
-### Create protobuf library for Java
-
-We assume you've cloned gRPC repository in your home directory.
-
-```bash
-$ sudo apt-get install maven
-$ cd ~/grpc/third_party/protobuf/java
-$ mvn package
-...

-
-### Clone grpc-java and get plugins
-
-```bash
-$ cd ~/work
-$ git clone https://github.com/grpc/grpc-java.git
-$ cd ./grpc-java
-$ git checkout -b v1.4.0 v1.4.0
-$ cd ./all

-
-### Generate stub classes
-
-```bash
-$ cd $GOPATH/src/github.com/osrg/gobgp/tools/grpc
-$ mkdir -p java/src
-$ cd java
-$ GOBGP_API=$GOPATH/src/github.com/osrg/gobgp/api

-is an example to show neighbor information.
-
-Let's build and run it. However we need to download and copy some dependencies
-beforehand.
-
