My Java method is expecting DataInputstream as argument. I need to read file contents in ruby and call that Java method with these contents. contents = IO.read('filename') JavaObj.method(datainputstream) How to convert contents (string) to inputstream? Please help.

I would use something like java.io.DataInputStream.new(java.io.ByteArrayInputStream.new(content.to_java.bytes)) -christian

Hi, its not the same but i remenber to read about this and take this solution to read a image resource from a jar and write it to a profile dir. Basically i use a java class to read and other to content the readed image. I think code that can solve your problem can look similar to this. class ConfigWebResources def initialize @web_resource1_name = Dir.home.to_s + "/.rmldonkey/log6.png" if File.exists?(@web_resource1_name) puts @web_resource1_name + " resource readed..." else is = Java::BufferedImage.new is = javax.imageio.ImageIO.read(java.lang.Object.new.java_class.resource("/log6.png")) javax.imageio.ImageIO.write(is,"png".to_java, java.io.File.new(@web_resource1_name)) puts @web_resource1_name + " resource write..." end #if File.exists?(@web_resource1_name) end #def configWebResources end #class ConfigWebResources Manuel Ramos Caro.
