Subject RE: [vfs] - Problem with httpclient
Date Thu, 03 Feb 2011 16:09:36 GMT

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");
}

Saludos Cordiales,
