Java classpath for yajb

Ruby
1

Hi,

I’m trying to use a java class via yajb in Ruby on Rails.
yajb works fine for calling Java library classes, but I can’t get my
own java classes to work.

I have:

  • a class file anon.example.ImportTest in directory
    /home/elmar/railswork/myapp/lib/java/anon/example
  • a controller with JBRIDGE_OPTIONS = { :classpath =>
    ‘/home/elmar/railswork/myapp/lib/java’ }

yet instantiating a ruby variable like
testvar = jnew :ImportTest
fails.

Is there anything obvious I’m doing wrong?

Thanks for any help,
Elmar

Hm, check out this YAJB presentation here:

I think Paul said something about CLASSPATH in there…

Here’s a direct link to the slides:

You have to configure YAJB with the JBRIDGE_OPTIONS constant. There’s
an example on page 9.

Feel free to e-mail me directly ([email protected]) if you have other
questions.

Good Luck,
Paul
