ssh username@magno (or whatever the IP is assigned to magno in hosts file)
>netstat -ab | grep 80
//if you do not have HTTPServer running on 80 you will get no results
//if you do have HTTPServer running on Port 80 you should see output
//also if your HttpClient executeMethod is declared as
public int executeMethod(HostConfiguration hostconfig, final HttpMethod method,
final HttpState state)
throws IOException, HttpException
//you should call executeMethod with all of the params initialised e.g.
try
{
int n=client.executeMethod(hostconfig,method,state)
}
catch(IOException ioe)
{
log.debug("Handle your IOException from client.executeMethod here");
}
catch(HttpException http_exception)
{
log.debug("Handle your HttpException from client.executeMethod here");
}
