Scripting Support in GFv3 Prelude - Full Version
- 1. Dynamic Languages in GlassFish v3 Prelude GlassFish Webinar Vivek Pandey Developer, Glassfish Team Sun Microsysems, Inc. 1
- 2. 2
- 3. GlassFish v3 - A Dynamic AppServer Productivity, performance • GlassFish v3 > Lightweight, Modular, Extensible, Embeddable • Reasonable and efficient deployment choice > Native, WAR style, embedded GlassFish • App Server feature for everyone > Database connection pooling > Native threading, non-blocking IO, ARP > Management – Monitor, Deploy, Troubleshooting > Access to enterprise stack – Metro, Jersey, JMS/MQ, Grizzly, JBI etc. 3
- 4. Overall Architecture 4
- 5. JRuby on Rails 5
- 6. Why Ruby on GlassFish? • GlassFish v3 server is tested platform > Co-host Java and Rails > Known Deployment and Management • “Green” alternative – One command, One instance, One process • Multiple Requests by a Single Application • Database Connection Pooling • Not just Rails – Merb, Sinatra... 6
- 7. More benefits... • No packaging, simple deployment > asadmin deploy depot/ • Deploy as WAR > warble #creates WAR file > asadmin deploy depot.war • Tested JRuby runtime at Updatecenter > bin/updatetool > No more config needed • Commercially supported by Sun • http://wiki.glassfish.java.net/Wiki.jsp?page=GettingStartedGuide 7
- 8. GlassFish v3 Runtime Grizzly Listener . Rails Web . XXX Adapter Adapter Adapter . Rails Runtime Pool JRuby 8
- 9. Runtime Pool Management • Automatic JRuby runtime pool management Gem Create JRuby Rails Startup Runtime JRuby Load Rails Environment Add to Rails Runtime Pool JRuby 9
- 10. Configuring JRuby Runtime Pool • On GlassFish v3 Prelude Server > System properties – -Djruby.runtime.min : Sets the fewest runtimes to have in the pool – -Djruby.runtime : Sets the initial number of runtimes to create – -Djruby.runtime.max : Sets the maximum number of runtimes to have active > Add these system properties as <jvm-options> elements inside domain.xml > Or, if using java CLI simply provide it using -D option – java -Djruby.home=... -Djruby.runtime.max=2 -jar modules/glassfish.jar 10
- 11. Configuring JRuby Runtime Pool • GlassFish gem > CLI options – -n, --runtimes – Number of JRuby runtimes to crete initially – --runtimes-min – Minimum JRuby runtimes to crete – --runtimes-max – Maximum number of JRuby runtimes to crete > glassfish -n 2 –runtimes-min 1 –runtimes-max 6 – Starts glassfish gem with 2 JRuby runtimes, the minimum pool size is 1 and maximum size it can grow up to is 6 11
- 12. JRuby Bundle - Updatecenter • glassfish-install/bin/updatetool 12
- 13. NetBeans Tooling • NetBeans support > Develop, deploy debug > Screencast – http://weblogs.java.net/blog/arungupta/archive/2008/11/screencast_26_d.html 13
- 14. GlassFish gem • Rails developer friendly • Based on GlassFish v3 nucleus • Distributed as ruby gem • Install > gem install glassfish • Run > cd myAp > glassfish • More info > http://glassfishgem.rubyforge.org/ 14
- 15. GlassFish Gem • Latest 0.9.0 released • Features > Rack based architecture – Pluggable ruby frameworks > Merb support – JRuby and Merb native extension issue $jruby -S gem install merb-core merb-more $merb-gen core hello $cd hello $glassfish • Framework auto-detection > Need just one command 'glassfish' • Details at: http://glassfishgems.rubyforge.org/ 15
- 16. Demo – GlassFish Gem • Demo screencast > http://mediacast.sun.com/users/vivek.pandey/media/gemdemo 16
- 17. Groovy on Grails 17
- 18. Groovy on Grails • An MVC frameworks • Based on Groovy, Spring, Hibernate, SiteMesh > But hides all the complexity • Adopts Rails paradigms 18
- 19. Grails – Setup and Installation • Install Grails IPS package using updatetool > Grails package is installed inside 'glassfish' directory • Grails IPS package > Provides the following benefits over Grails distributions found elsewhere – grails shaed-war – Lightweight, efficient application WAR – Less prone to OOM due to lack of PermGen space on hot deployments – grails run-app – Runs GlassFish v3 Prelude in embedded mode – Develop and test your grails app on the same server you would deploy during production • Set GRAILS_HOME environment variable > export GRAILS_HOME=glassfish-install/grails 19
- 20. Groovy on Grails - Updatecenter • glassfish-install/bin/updatetool 20
- 21. Groovy on Grails • Development and production on the same server > Develop using GlassFish v3 embedded server – grails run-app 21
- 22. Groovy on Grails • Development and production on the same server > Develop using GlassFish v3 embedded server – grails run-app > Production deployment – asadmin deploy grailsApp.war 22
- 23. Groovy on Grails • Development and production on the same server > Develop using GlassFish v3 embedded server – grails run-app > Production deployment – asadmin deploy grailsApp.war • Efficient WAR packaging > grails shared-war – Creates smaller WARs ~200KB vs 18MB – asadmin deploy –-libraries $GRAILS_HOME/lib/glassfish- grails.jar grailsApp.war 23
- 24. Groovy on Grails • Development and production on the same server > Develop using GlassFish v3 embedded server – grails run-app > Production deployment – asadmin deploy grailsApp.war • Efficient WAR packaging > grails shared-war – Creates smaller WARs ~200KB vs 18MB – asadmin deploy –-libraries $GRAILS_HOME/lib/glassfish- grails grailsApp.war • For details > http://wiki.glassfish.java.net/Wiki.jsp?page=GrailsGettingStarted 24
- 25. Groovy on Grails – Screencast • From Zero to Grails in 5 minutes with GlassFish v3 Prelude > https://slx.sun.com/1179271912 25
- 26. Jython on Django • Jython 2.5 nearing release > Jython 2.5 beta out > Being developed at – http://www.jython.org/Project/ • Currently WAR deployment approach > Using Django-Jython project – http://django-jython.googlecode.com/ • Native Django application deployment in works 26
- 27. PHP 27
- 28. PHP • Quercus (Caucho) > Open Source (GPL) PHP 5 implementation in Java > WAR packaging > WordPress, MediaWiki, phpBB, Joomla • PHP/Java Bridge > Open Source (LGPL) > XML based network protocol for native PHP > Faster, easier than JNI > Java native threads used for concurrent requests > PHP and JSP session sharing 28
- 29. Scala on Lift 29
- 30. Scala on Lift • Lifts apps packaged as WAR > asadmin deploy liftApp.war • For details on developing and deploying Lift applications see > http://wiki.glassfish.java.net/Wiki.jsp?page=GettingStartedWithLiftOnGlassFish 30
