This is a remote Python console allowing to manipulate your JVM application in runtime.

See my article in Russian for more details.

1. Add following repository definition to pom.xml:

    <repository>
      <id>Rjyc Repository</id>
      <url>http://siasia.github.com/maven2</url>
    </repository>
   

2. and a dependency itself:

    <dependency>
      <groupId>org.python</groupId>
      <artifactId>rjyc</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>
   

1. Inject the remote console server into the project:

    import net.rjyc.Server;
    import java.util.*;
   
    public class Test {
      public int test;
      public static void main(String [] args) {
        Map<String, Object> locals = new HashMap<String, Object>() { //create locals for your interpreter
          put("context", new Test());
        };
        /* start the server listening for localhost:8080 
         * with a context variable set to the instance of Test
         */
        new Server("localhost", 8080, locals).start(); 
      }
    }
   

2. Grab client.py and run it like this:

    siasia@siasia ~/projects/rjyc % python2 client.py localhost 8080
    >>> print 1
    1
    >>> for i in range(1, 5):
    ...     print i
    ... 
    1
    2
    3
    4
    >>> context
    Test@7c9586
    >>> context.test
    0
    >>> context.test = 1
    >>> context.test
    1
    >>> context.
    context.__class__         context.__hash__          context.__reduce_ex__     context.equals            context.notifyAll
    context.__delattr__       context.__init__          context.__repr__          context.getClass          context.test
    context.__doc__           context.__ne__            context.__setattr__       context.hashCode          context.toString
    context.__eq__            context.__new__           context.__str__           context.main              context.wait
    context.__getattribute__  context.__reduce__        context.class             context.notify            
    >>> import java
    >>> java.
    java.__name__  java.io        java.lang      java.net       java.nio        java.security  java.util      
    >>> java.io.FileOutputStream('/tmp/test.txt')
