CS3 refuses to work

Author	Message
fyang15 Posts: 35	Posted 15:50 Mar 05, 2020 \| For CS 3220 labs, this is the third time I followed the exact instruction and uploaded all needed files and at the very last, web.xml. Yet, It still stubbornly gives me a 404. Any fix for this? It's really irritating to fix under the lab's tight time constraint and I'm losing a lot of points for it. I don't even know why getting it to work on CS3 should be such a huge portion of the grade when the code is clearly working, but CS3 isn't. Last edited by fyang15 at 15:51 Mar 05, 2020.

cysun Posts: 2935	Posted 16:02 Mar 05, 2020 \| You code doesn't work on CS3 because you have multiple classes on the server mapped to the same URL. See the screenshot below: Read the lecture notes on deployment, especially slide 6-8.

See the screenshot below: Read the lecture notes on deployment, especially slide 6-8. I just tried deleting all old assignments, still can't get it to show up. I am using WinSCP, still don't know how to use the "touch" command yet, but I'll try to figure it out. Thanks for the help. Last edited by fyang15 at 16:22 Mar 05, 2020.

Here's your home folder: and here's what's under www: BTW you are missing Logout

I did include invalidate() in Members' doPost. Last edited by fyang15 at 18:35 Mar 05, 2020.

I chose to delete the contents of the folder because I don't think you can put several web.xml on cs3 (unless I'm wrong). So you can't 'mix' 2 projects, only code the 2 servlets in the same project.

For us web.xml doesn't really matter because all the projects have pretty much the same web.xml (unless you manually add additional settings in web.xml). There can only be one web.xml on the server for each account because the server treats all the projects in an account as one project. With that said, if you want to deploy two projects, it's perfectly fine that the web.xml of the second project overwrites the first one.

So I remove the lab 11 when I put the lab 12. Can I put the lab 11 again?

qbriola Posts: 4	Posted 12:34 Mar 06, 2020 \| OK, so I added an issue to choose the deployment method (with / without deleting data). I will fix it soon https://github.com/gastbob40/cs3_lab_deploy/issues/1 EDIT The issue has been realized, and the script now takes an option to choose the method of deployment.
