- - ### Constructor Detail

    - #### CommandEnvironment

          public CommandEnvironment(String cmdpath,
                                    String[] argv)

      Create a CommandEnvironment with all the necessary information.
      Parameters:
        `cmdpath` - the name of the java executable, including the full path, or `null`, meaning "use rmid's default". The named program must be able to accept multiple `-Dpropname=value` options (as documented for the "java" tool)
        `argv` - extra options which will be used in creating the ActivationGroup. Null has the same effect as an empty list.
      Since:
        1.2

  - ### Method Detail

    - #### getCommandPath

          public String getCommandPath()

      Fetch the configured path-qualified java command name.
      Returns:

    - #### getCommandOptions

          public String[] getCommandOptions()

      Parameters:
        `obj` - the Object to compare with
      Returns:
        true if these Objects are equal; false otherwise.
