Hi,

In my application a mobile device sends a request to tomcat servlet, and  
then the servlet needs to send a request to a rails controller method  
for some processing to be done. After the processing the rails will send  
a http request to another tomcat servlet to send the processed results  
back to the device.

I cannot avoid the tomcat route because the gateway to send/receive  
request to mobile device has the api in java only. I have to go through  
this route only.

But my problem is that from the ruby code, I can do the processing and  
send the request to tomcat also to send the response. But how do I tell  
the action in controller that there is no view associated to be shown,  
and after Net:HTTP call nothing needs to be done.

Thanks.

if you have nothing to render, you can write this:

render :text =\> “”, :layout =\> false

this will not render your layout nor any output
