Rjb heap size OR call ruby methods from java

Ruby
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)
