How to GZIP output from Tiles 2?

Hi!

I tried to write my own GZIPFilter that would do the trick of 
compressing HTML outputted from Tiles but I get the following exception 
when I try to get the OutputStream from HttpServletResponse for GZipping:

java.lang.IllegalStateException: getWriter() has already been called for 
this response

Is there any way enable compression in Tiles? Or some other solution(s) 
to circumvent this problem?

This is normal, every webapp writes in the output stream! It's not
dependent on Tiles.

You usually have to configure your application server. For example in Tomcat:
