Hi,
  I am working on a J2EE project which is nearing completion and I would like to test it. I plan to use the apache grinder 3 test tool.

I have followed all the steps given in this very useful article to get the grinder started;
http://www.anticlue.net/archives/000395.htm

But when I type in the following command on the command prompt I get the following error:

C:\>java net.grinder.TCPProxy -httpplugin -console
Script will be generated to the files 'httpscript.py' and 'httpscript_tests.py'
4/21/05 1:06:49 PM (tcpproxy): Initialising as an HTTP/HTTPS proxy with the

parameters:

   Request filters: HTTPPluginTCPProxyFilter

   Response filters: HTTPPluginTCPProxyResponseFilter

   Local address: localhost:8001

4/21/05 1:06:49 PM (tcpproxy): Could not initialise engine:


As you can see it does not give me any indication of what exactly is wrong. Any help is extemely appreciated

Thanks,
Siva

Try to use the new http plugin the one you mentioned is depricated. The newest version should work pretty good.
