JRuby: create Java InputStream or byte [] from RubyString

Question

I have a Java method that I want to call from JRuby. The argument I want to pass is the usual string ( org.jruby.RubyString), but the Java method is overloaded to accept either:

• java.io.InputStream
• byte[]
• com.google.protobuf.ByteString

In what simple way can I convert my string to an instance of one of these classes?

Answer 1

Found: org.jruby.RubyString # to_java_bytes .
