Redmine on GlassFish - Ruby-on-Rails Project Management Application

Redmine is a flexible project management web application written using Ruby on Rails framework. The feature list is pretty comprehensive from the usual suspects like multiple projects, role-based control, forums/wikis/SCM for each project to enterprise level features such as LDAP-authentication and multiple languages. It is cross-platform and cross-database and deploys very nicely on GlassFish v3.

GlassFish v3 modularity and extensibility allows Rails applications to be deployed without any modification (no WARing). This blog explains the steps on how to deploy Redmine on GlassFish and shows some screenshots later. More documentation is available in Redmine Guide.

1. Check out the most stable release of Redmine by giving the command:
   
   

   ~/testbed/redmine >svn co http://redmine.rubyforge.org/svn/branches/0.7-stable redmine-0.7

2. Configure the database
1. Start your MySQL server 
   
   

   ~/testbed/redmine >sudo mysqld_safe --user root Starting mysqld daemon with databases from /usr/local/mysql/data

2. Create the database as:
   
   

   ~/testbed/redmine/redmine-0.7 >../jruby-1.1.1/bin/jruby -S rake db:create (in /Users/arungupta/testbed/redmine/redmine-0.7)

3. Migrate the database as:
   
   

   ~/testbed/redmine/redmine-0.7 >../jruby-1.1.1/bin/jruby -S rake db:migrate (in /Users/arungupta/testbed/redmine/redmine-0.7) == 1 Setup: migrating ========================================================= -- create_table("attachments", {:force=>true})    -> 0.2840s -- create_table("auth_sources", {:force=>true})    -> 0.0540s -- create_table("custom_fields", {:force=>true})    -> 0.0430s -- create_table("custom_fields_projects", {:id=>false, :force=>true})    -> 0.0080s -- create_table("custom_fields_trackers", {:id=>false, :force=>true})    -> 0.0500s . . . == 90 ChangeVersionsNameLimit: migrating ====================================== -- change_column(:versions, :name, :string, {:limit=>nil})    -> 0.0220s == 90 ChangeVersionsNameLimit: migrated (0.0220s) ============================= == 91 ChangeChangesetsRevisionToString: migrating ============================= -- change_column(:changesets, :revision, :string, {:null=>false})    -> 0.0210s == 91 ChangeChangesetsRevisionToString: migrated (0.0230s) ==================== == 92 ChangeChangesFromRevisionToString: migrating ============================ -- change_column(:changes, :from_revision, :string)    -> 0.0130s == 92 ChangeChangesFromRevisionToString: migrated (0.0150s) ===================

3. Download, Install and Configure GlassFish v3
1. Download GlassFish v3 from here.
2. Unzip the downloaded bundle.
3. Add the following fragment as the last line in "glassfishv3-tp2/glassfish/config/asenv.conf" file:
   
   

   JRUBY_HOME="/Users/arungupta/testbed/redmine/jruby-1.1.1"

4. Deploy Redmine as:
   
   

   ~/testbed/redmine >./glassfishv3-tp2/glassfish/bin/asadmin deploy redmine-0.7 Command deploy executed successfully.

   
   ... and the GlassFish console shows:
