rjb heap size OR call ruby methods from java

Discussion in 'Ruby' started by Shashank Agarwal, Jun 29, 2008.

  1. I've been using rjb (ruby java bridge) to use a method from a Java
    library. Problem is, that I run out of heap while running that method.
    I'm on a Windows machine, and I increased the max heap size for Java
    from the Control Panel, but the problem continued. Is there a way to fix
    that?

    If not, is it possible to call Ruby methods from Java, something like
    Inline? Xruby might help, but I wonder if it could help (never used it,
    and the currently reported problems put me off).

    There is also jruby ... a Java implementation of the entire (or almost) Ruby language -- with this information on Java integration:

    I believe that when you load the jvm, you can pass along the max heap
    size as a parameter:

    Rjb::load(classpath = '.', jvmargs=[])

    I haven't used it myself but they should be similar to the command line
    arguments:

    - -Xms32m -Xmx128m

    (these are the defaults which you should increase)
