Error: wrong number of arguments (1 for 0)

Ruby JRuby
1

Hi,

I am working on an application with Jruby and rails. I recently upgraded
Jruby version to 1.4 and rails (Jruby gem) version to 2.3.5.

I randomly get the following error. The error occurs before any of the
application code is called. I am not sure why rails or jruby is passing
some arguments to controller method. The problem only occurs when the
project is deployed in tomcat. It works fine with mongrel.

Any help will be greatly appreciated.

Error:

ArgumentError in Client/authController#login
wrong number of arguments (1 for 0)

After a few print statements in active_support/dependencies.rb class in
‘qualified_const_defined?’ method, I notice that this error occurs after
this method is trying to resolve a Java class named Client with some
package name. Could there be a conflict with resolving the package
Client of the controller Client::AuthController?

It certainly could be. Can you file a bug for it and try to reduce it
to a simple case? You may also want to try on JRuby 1.5, where some
class resolution/const_missing issues have been fixed.

Thanks Charles,

I’ll try to reduce the problem. I have filed a bug for it:
http://jira.codehaus.org/browse/JRUBY-4613

I thought the latest version of JRuby was 1.4. Where can I get version
1.5 from?

Hi,

I was finally able to resolve the problem. It was related to another
issue that I have posted:
http://www.ruby-forum.com/topic/205436#new

Upgrading jruby-rack jar file from 0.9.5 to 0.9.6, resolved the problem.

From what I understand, there is a problem with locking in jruby-rack
jar file, which was causing a deadlock. I was able to get around that by
removing a lock in action-pack gem reloader class (see the above post
for more info).
I didn’t get any deadlocks after that, but it removing the lock caused
problem with loading of the classes.

Thank you for all your help. I really appreciate it.

Regards,
Jas
