Hello,

I’m using class RestClient for communication between server and client.  
One example is:

params = {:status =\> “finished”}  
resource = RestClient::Resource.new  
“[http://localhost:3000/BuildJob/220376999](http://localhost:3000/BuildJob/220376999)”  
begin  
resource.put params, :content\_type =\> ‘text/plain’  
rescue Exception =\> err  
puts err.to\_s  
end

where “status” is a string field in model class “BuildJob” and  
“220376999” is the id of the BuildJob.

What I want to do is updating the field “status” in the model  
“BuildJob”. I always get the error:

“HTTP status code 500”

I’m already using the following command to retrieve information about  
build jobs:

xml = RestClient.get “[http://localhost:3000/BuildJob?status=pending](http://localhost:3000/BuildJob?status=pending)”

This code is functioning without errors.

Any idea what’s wrong?

Thanks  
Martin
