Capistrano 1.4  
Source system: Win XP  
Target system: Red Hat 10.x

BACKGROUND:  
I recently added the following to my environment.rb file in order to use  
the Ruby-Java bridge (RJB):

require ‘rjb’  
gem ‘rjb’, ‘\>= 1.0.3’  
Rjb::load("#{RAILS\_ROOT}/lib/jxl.jar", [’-Xmx512M’])

PROBLEM:  
When I deploy to my remote system, when this line in deploy.rb:

run “cd #{current\_path}; rake db:migrate RAILS\_ENV=test;”

is executed, I see the following in the log:

executing “cd ~dusan/eSimplyTest/current; rake db:migrate  
RAILS\_ENV=test;”  
servers: [“192.168.1.102”]  
[192.168.1.102] executing command  
\*\* [out :: 192.168.1.102] /usr/bin/rake:17:Warning: require\_gem is  
obsolete. Use gem instead.  
\*\* [out :: 192.168.1.102] (in  
/home/dusan/eSimplyTest/releases/20070219185329)  
\*\* [out :: 192.168.1.102] rake aborted!  
\*\* [out :: 192.168.1.102] can’t create Java VM  
\*\* [out :: 192.168.1.102]  
\*\* [out :: 192.168.1.102] (See full trace by running task with --trace)

Notice the “can’t create Java VM” line, as though it’s attempting to run  
the code in environment.rb. I’ve verified that this is the problem by  
commenting out the Jrb setup lines in environment.rb and redeploying and  
not seeing the error anymore.

What’s going on here? Why is a rake db:migrate command attempting to  
run environment.rb?

If I run “cd ~dusan/eSimplyTest/current; rake db:migrate  
RAILS\_ENV=test;” on the target server by hand as the correct user, I  
don’t see any mention of Java VM, and the migrate proceeeds normally.  
Also, if I run a SSH session from my Windows box to the target server  
and issue this command, it works fine - I don’t see this error.

Does anyone understand why stuff in my environment.rb is affecting my  
deployment with Capistrano in this way?

Any insight is appreciated.

Thanks,  
Wes

As it turns out, this is due to the fact that the ssh calls do not  
execute the regular login script for the user on the remote host.

Adding some statements to set environment variables to allow Java stuff  
to work did the trick.
