scjson

scjson Java Package

This directory contains the Java implementation of scjson using Maven. It provides a command line interface to convert between .scxml and .scjson documents and validate them against the shared schema.

Build

cd java && mvn package -DskipTests

Command Line Usage

java -jar target/scjson.jar json path/to/machine.scxml
java -jar target/scjson.jar xml path/to/machine.scjson
java -jar target/scjson.jar validate path/to/dir -r
java -jar target/scjson.jar run path/to/machine.scxml -e events.json -o trace.json

Java Proxy Setup

The Java implementation uses Maven. If your environment requires an HTTP/HTTPS proxy, create ~/.m2/settings.xml with proxy settings before building:

<settings>
  <proxies>
    <proxy>
      <id>internal-proxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxy</host>
      <port>8080</port>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>s
    </proxy>
    <proxy>
      <id>internal-proxy-https</id>
      <active>true</active>
      <protocol>https</protocol>
      <host>proxy</host>
      <port>8080</port>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
  </proxies>
</settings>

Build the module with:

cd java && mvn clean install -DskipTests -B && cd ..

Running SCXML documents

You can execute a state machine using the CLI:

java -jar target/scjson.jar run examples/example.scxml -e examples/events.json -o trace.json

This uses ScxmlRunner under the hood and requires the Apache Commons SCXML library. Ensure Maven can download dependencies or has them cached locally.
