[Routing] problem for getting back result from postgres

[javad sadidi]

hi
I am working on FOSS4G 2010: FOSS4G routing with pgRouting tools,
OpenStreetMap road data and
GeoExt<http://www.pgrouting.org/docs/foss4g2010/index.html>workshop
I have my area to implement routing methods in ubuntu 10.04.
also I have the following packages: Mapserver, geoext, openlayer and
project4.js
I have copied all packages in mapserver root directory.
I can see my maps and can put the start and end destination points on the
map in browsers and till here every thing is ok but I cant see the result. I
mean there is nothing as routing result , what is the problem and the
solution.
do I need install Mapbinder inside root directory of mapserver I mean
var/www ?
do you think that the program cant connect to pgsql?
or it cant bring the result from pgsql in json format?
when I put points or change the algorithm nothing is happend.
I have waste my time 2 weeks for it and I get nothing.
please help me
best regards
