The major reason to make everythign use the SolrDispatchFilter is that we would have consistent error handling. Currently,
SolrServlet spits back errors using:
PrintWriter writer = response.getWriter();
and the SolrDispatchFilter spits them back using:
res.sendError( code, ex.getMessage() );
Using "sendError" lets the servlet container format the code so it shows up ok in a browser. Without it, you may have to view source to see the error.
Aditionaly, SolrDispatchFilter is more decerning about including stack trace. It only includes a stack trace of 500 or an unknown response code.
Eventually, the error should probably be formatted in the requested format -
