I am writing this jruby script for the SNMP management of the wireless 
equipment installed in my campus. The way i have my script has 3 java 
classes corresponding to the 3 main scripts that i have in ruby.Below i 
paste the code for the rum method of one of my class categories (it just 
calls the corresponding ruby script):


  public void run() {
      System.out.println(getName());
      try {
          ScriptEngineManager factory = new ScriptEngineManager();
      // Create a JRuby engine.
            ScriptEngine engine = factory.getEngineByName("jruby");
      // Enable the JRuby script engine to invoke a script in a file.
            Invocable inv = (Invocable) engine;
      // Open a file reader on the external JRuby script file.
            FileReader f = new 
FileReader("/root/NetBeansProjects/java_thread_script_test/src/java_thread_script_test/cpeping.rb");
      // Evaluate (execute) the script. Once evaluated, any functions
      // in the script can be called with the invokeFunction method.
            engine.eval(f);
      }//end of try

Now, the problem is that i have made 3 classes and each of these classes 
have to create 8 threads each (in java). so what i need is that i pass 
on the IP Address and and an integer to the ruby script so that each 
category (8 threads) can use the same ruby file instead of duplicating 
the ruby scripts for individual threads.

I guess this much detail will be enough to seek your help. Waiting for 
your reply.......

Thanks..
