Trying to send back error json from Servlet filter instead of allowing the request to go through

I have implemented a Filter for a servlet(java). But there is a condition that in some cases i should not be allowing the request to go through( chain.doFilter() ) and allow access to Servlet.

Instead i need to send Error json object back to browser form filter itself. Please let me know how this can be implemented.

Each Filter has access to the ServletResponse. Simply get its OutputStream and use it to write the JSON content. (And don't follow the chain.)
