问题
I have created a JRuby desktop application. Now I need to install on different platforms(Windows, Linux, Mac). Can any one help me on this
Which is the painless method to create installation files OR executables with jruby. I googled and tried with RubyScript2exe, OCRA but none of these succeeded(really dont understood much). I am a noobie.. I really need it...
EDIT - TRYING A SIMPLE METHOD as jrubyc can create java equivalent class files(described here)
To start with packaging I created a HelloWorld.rb. Below is the file
require 'jruby/core_ext'
swingClasses = %w(JFrame JPanel JPopupMenu JMenuItem
BorderFactory JLabel JTree JTextField Box JList
JComboBox ImageIcon BoxLayout JPasswordField
JButton SwingConstants border.LineBorder
)
swingClasses.each {|swc| java_import "javax.swing.#{swc}"}
awtClasses = %w(Color Dimension EventQueue event.ActionListener
event.ActionEvent event.MouseAdapter)
awtClasses.each {|awc| java_import "java.awt.#{awc}"}
class HelloWorld < JFrame
def initialize
super "welcome"
main_panel = JPanel.new
main_panel.setLayout BoxLayout.new main_panel, BoxLayout::Y_AXIS
top_panel = JPanel.new
top_panel.setLayout nil
top_panel.setBackground Color.green
main_panel.add top_panel
self.add main_panel
self.pack
self.setDefaultCloseOperation JFrame::EXIT_ON_CLOSE
self.setSize 800,700
self.setVisible true
end
end
HelloWorld.new
The file is running fine with the command: jruby HelloWorld.rb
. Also I have managed to created .jar file using: jar cvfe HelloWorld.jar HelloWorld HelloWorld.class
with the .class file created using: jrubyc HelloWorld.rb
But when I run the jar using: java -jar HelloWorld.jar
, I am getting the below error.
Error: A JNI error has occurred, please check your installation and try again

... 7 more
Please throw me some lights on how to solve this...
EDIT This found to be becouse of the lack of additional files OR classfiles. Didn't find any file/jar named org.jruby.ParseResult in jruby installed. How we can know what all files need to be added for an application as I am not using any particular libraries. I am expecting it to run if JRE installed. Please guide me. Can some one share me what I can do here
