I am writing a script that references a few Java libraries that expect
some “.properties” files to be in the classpath. I can set the
classpath
in the shell before I run the jruby executable, but it would be much
nicer
if I could dynamically reference the “.properties” files from my script.
Does anyone know how you can add a file that isn’t a class or a jar to
your classpath dynamically?
Thanks in advance!

I just append to $CLASSPATH like so
$CLASSPATH << “path/to/properties”
or get fancier with something like
#!/usr/bin/env jruby
require ‘java’
[“#{File.dirname FILE}/…/build/”, “#{File.dirname
FILE}/…/lib/”].concat(Dir[“#{File.dirname
FILE}/…/lib/*.jar”]).each { |jar| $CLASSPATH << jar }
Hope this helps.
That should work.

Thanks Johnny! That worked like a charm. I’m now able to add all of
the properties files to my app at runtime.

#!/usr/bin/env jruby

Wow. That was a little scary I also found the following line for
importing all of your jar files:
Dir['lib/java/*.jar'].each { |jar| require jar }
Thanks again!
