Hi all

I have a ruby script that calls a web service which works just fine,  
However when i try to use the same code from a rails model I get the  
following error:

uninitialized constant SOAP::Mapping::EncodedRegistry

I have tried to load the gem soap4r from both the model and the  
config/environment.rb files but i still get the same error

Any ideas on what I’m doing wrong ???

Thanks

Hello,

It seems that when you ‘require’ soap4r, it conflicts with Ruby’s soap  
library and Rails tries to use Ruby’s soap library instead of soap4r.

Copy the folder \ruby\gems\1.8\gems\soap4r-1.5.5.20061022\lib\soap to  
\ruby\lib\ruby\1.8\soap and try again. It worked for me.

Hope this helps
