GlassFish v3 gem on JRuby 1.1 RC2

1. 260 issues resolved
2. Large IO refactoring
3. Less memory than previous release
1. Control total number of JIT'd methods
2. Support a JIT cache between runtimes to return permgen
3. 50-70% reduction in generated methods

1. Download JRuby 1.1 RC2. 
2. Install Rails and create a simple Rails application as described in TOTD #24.
3. Install GlassFish v3 gem using the command as shown below:
   
   bin/jruby -S gem install glassfish             
JRuby limited openssl loaded. gem install jruby-openssl for full support.
http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL
Successfully installed glassfish-0.1.1-universal-java
1 gem installed
4. And now the simple application can be easily deployed on GlassFish gem as:
   
   jruby -S glassfish_rails hello
   
   Notice this command needs to be given from the parent directory of the application. The Applcation environment is as shown below:
   
   
   
   and the application output looks like exactly as expected:

• It's not clear to me how to add RC2 to netbeans 6.1 m1. It supports multiple ruby platform. It expect a file with a specific format to help it identify the platform. I don't see such a file in the zip.

  Thanks,
  Peter

• Arun,

  Two more related issues, what about jruby-complete I don't see a new
  version. Is it still needed to deploy to say Tomcat? Also as far as gem, when I am running in Tomcat, jruby points to this 'default user\.jruby' directory for all the gems even though they are included in the war.
  Does this explosion happen at deployment time?

• Ok, I figured out how to add new platform to netbeans by giving in the appropriate jruby or ruby bat file. And the new rc2 complete jar was uploaded on the 18th. Now I am still having this Tomcat issue because RC2 has a different scheme for finding gems than RC1. Help!

  Thanks,
  Peter
