Why JRuby• You can use java resources.• More easy to deploy to Windows.• True multithreading.• JRuby is just a .jar ﬁle. http://bit.ly/cPNg9f

Using Java Resources

Wrapping a Library(1)require java# create objectspdf = com.itextpdf.text.Document.newpara =com.itextpdf.text.Paragraph.newUsing Java resources from JRubyfile = java.io.FileOutputStream.newpdf_demo.pdf https://gist.github.com/e4b1d813394e58188e59

Wrapping a Library(2)# get_instance is an alias forgetInstancecom.itextpdf.text.pdf.PdfWriter.get_instance(pdf, file)pdf.openpdf.add parapdf.close https://gist.github.com/e4b1d813394e58188e59

Wrapping a Library(3)• Run • jruby -J-cp itextpdf-5.1.2.jar pdf_demo.rb

Classpath(1)• Environment Variable • set RUBYOPT=-IC:jrubyitext • set CLASSPATH=%CLASSPATH%C:jruby itext

Using Objects’ Static Methods(1)API: com.itextpdf.text.PageSize http://api.itextpdf.com/itext/com/itextpdf/text/PageSize.html

Data Type Conversionhttp://kenai.com/projects/jruby/pages/CallingJavaFromJRuby#Ruby_to_Java

JRoR on Windows Environment

Using MSSQL(1)Step1: add adapter#Gemfilegem activerecord-jdbc-adaptergem activerecord-jdbcmssql-adapter

Using MSSQL(2) Step2: Download sqljdbc4.jar Step3: add classpath#config/environment.rbrequire "#{Rails.root}/lib/java/sqljdbc4.jar"

Using MSSQL(3)Step4: conﬁg databasedevelopment: adapter: jdbc username: sa password: password driver: com.microsoft.sqlserver.jdbc.SQLServerDriver url: jdbc:sqlserver://hostname:1433;databaseName=myapp pool: 5 timeout: 5000

Application Server Trinidad• Simple library to run rails and rackup applications into an embedded Apache Tomcat• https://github.com/trinidad/trinidad• add gem ‘trinidad’ to Gemﬁle• jruby -S trinidad

Running Trinidad as Windows Service(1)• add gem ‘trinidad_init_services’ to Gemﬁle• https://github.com/trinidad/ trinidad_init_services• It’s base on Apache Commons Daemon

Running Trinidad as Windows Service(2)• If you are using 64-bit Server, you should replace procrun.exe to 64-bit version.• jruby -S trinidad_init_service

IIS Proxy to Trinidad• using ISAPI_Rewrite 3• conﬁg: RewriteEngine on RewriteBase / RewriteLog "C:myapplogrewrite.log" RewriteLogLevel 9 RewriteProxy (.*) http://localhost:3000/$1• Single server license: $99

Background Process Resque• redis: • https://github.com/dmajkic/redis/downloads• resque: • https://github.com/defunkt/resque• jruby" -S rake resque:workers VERBOSE=true COUNT=3 QUEUE=* RAILS_ENV=production

DeploymentUsing NSIS to Deploy Rails App

Steps• Install JRuby• Copy app to suitable folder• Batch file for install gems• Batch file for database setting• Batch files for running resque, redis

Install JRubySection -InstallJRuby SEC0000 SetOutPath $INSTDIR File /r jruby_windowsjre_1_6_3.exe ExecWait $INSTDIRjruby_windowsjre_1_6_3.exe -q -dir"$INSTDIRjruby"SectionEnd

Copy App to Suitable FolderSection -CopyMyapp SEC0001 SetOutPath $INSTDIRmyapp SetOverwrite on File /r Myapp*SectionEnd

Batch File for Install Gems(1)Section -CreateFileForGemInstall SEC0003 FileOpen $9 $INSTDIRMyappscriptinstall_gem.bat w FileWrite $9 @echo off$r$n FileWrite $9 CD /D "$INSTDIRMyapp"$r$n FileWrite $9 set PATH=$INSTDIRjrubybin$r$n FileWrite $9 "$INSTDIRjrubybinjruby" -S gem install"vendorcachebundler-1.0.18.gem"$r$n FileWrite $9 "$INSTDIRjrubybinjruby" -S bundleinstall --local$r$n FileClose $9SectionEnd

Batch File for Database SettingSection -CreateFileForDBConfig SEC0005 FileOpen $9 $INSTDIRMyappscriptconfig_db.bat w FileWrite $9 @echo off$r$n FileWrite $9 CD /D "$INSTDIRMyapp"$r$n FileWrite $9 "$INSTDIRjrubybinjruby" -S rakedb:migrate RAILS_ENV=production$r$n FileWrite $9 "$INSTDIRjrubybinjruby" -S rakedb:seed RAILS_ENV=production$r$n FileClose $9SectionEnd

Batch File for RedisSection -CreateFileForRedis SEC0007 FileOpen $9 $INSTDIRMyappscriptredis.bat w FileWrite $9 @echo off$r$n FileWrite $9 "$INSTDIRredisredis-server.exe"$r$n FileClose $9SectionEnd

Batch File for ResqueSection -CreateFileForResque SEC0008 FileOpen $9 $INSTDIRMyappscriptresque.bat w FileWrite $9 @echo off$r$n FileWrite $9 CD /D "$INSTDIRMyapp"$r$n FileWrite $9 "$INSTDIRjrubybinjruby" -S rake resque:workersVERBOSE=true COUNT=3 QUEUE=* RAILS_ENV=production$r$n FileClose $9SectionEnd

Redis and Resque are runningon the “Command Prompt”.hmm.....It’s not a good idea.
