Programmatically download file from servlet using form authentication on Tomcat

[Alec Swan <al...@gmail.com>]

Hello,

We have a servlet which generates a report and allows user to download
it as a CSV file. The servlet is deployed on Tomcat and secured using
form authentication.

We would like to to invoke the servlet and download the file
programmatically using Apache Commons HttpClient API. Could anybody
provide advice or code sample showing how to get HttpClient request
through form authentication?

Any help would be greatly appreciated.

Thanks

Commons HttpClient is legacy code - please consider using
HttpComponents HttpClient.

Have you had a look at the HttpComponents web-site?  http://hc.apache.org/
There's plenty of documentation there.

If you must use Commons HttpClient:

http://svn.apache.org/viewvc/httpcomponents/oac.hc3x/trunk/src/examples/

Otherwise, HC HttpClient:

http://hc.apache.org/httpcomponents-client-ga/examples.html

Both URLs have examples of form login.
