+# Working with Picodata using native Java driver
+
+## Requirements
+
+- JDK 8+ (17 and higher is recommended)
+- Docker or Podman
+
+## Running this example
+
+1. Clone this repo and build it using the Maven wraper script:
+
+```shell
+git clone https://git.picodata.io/picodata/picodata/examples/-/tree/master/picodata-java-example
+```
+
+```shell
+./mvnw install
+```
+
+2. Go to `src/main/resources` directory and run the Docker containers with example Picodata cluster:
+
+```shell
+docker-compose up -d
+```
+
+3. Set up driver user authorization for Picodata in the container:
+
+```shell
+docker-compose exec picodata-1 bash -c "echo -ne \"\\set language sql\nALTER USER \\\"admin\\\" WITH PASSWORD 'P@ssw0rd';\" | picodata admin /home/picouser/picodata-1/admin.sock"
+```
+
+4. Return to the initial directory `picodata-java-example` and launch the example application.
+
+
+For JDK 17 and higher:
+
+```shell
+_JAVA_OPTIONS="--add-exports=java.base/sun.nio.ch=ALL-UNNAMED --add-exports=java.base/jdk.internal.misc=ALL-UNNAMED --add-opens=java.base/sun.nio.ch=ALL-UNNAMED" ./mvnw exec:java
+```
+
+For older JDKs:
+
+```shell
+./mvnw exec:java
+```
+
+In case of successful run you should see logs like the following in your console:
+
+```
+[nioEventLoopGroup-2-1] INFO i.p.d.c.c.AbstractTarantoolConnectionManager - Connected to Tarantool server at /127.0.0.1:3301
+Insert result:
+row_count 1
+Select all characters after insert:
+metadata [{name=id, type=integer}, {name=name, type=string}, {name=year, type=integer}]
+rows [[2, Vasya, 2000]]
+[io.picodata.PicodataExample.main()] INFO i.p.d.c.c.AbstractTarantoolConnectionManager - Disconnected from /127.0.0.1:3301
