Hello, Pinit.

Anyone please help me on how to pass option to tell jrubyc to compile
ruby code to .class which compatible with java 1.5 ?

jrubyc --javac some_ruby_file.rb

This will work best if you’ve added java_signature calls above the
Ruby methods you plan on invoking from Java.

Thank you Ian,

 Do I or How I pass option for javac ? Do I need to pass --target

1.5 to make it work I want ?

You can use the “-J” option to pass options to the underlying javac
instance, like so:

jrubyc --javac -Jtarget -J1.5 some_ruby_file.rb
