I also face exactly the same problem:

Status code: 404 – Not Found
Description: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

@JTG2020: does it indicate that the /UserSignup is running? If I click the start command the first time nothing happens (application does not start). so i first click on the undeploy command and then the start command for the web application to start running. I don't know if you also faced this problem?

@Alfusainey
I think i faced same problem. I thought that probably i did not follow instructions correctly and hence followed same steps again. I also realized that after web-server start up it takes some time for DB to be available based on logs. I am not sure if that’s what causing the issue.

thanks! let's hope that this issue gets resolved soon

Answer 4 · 2018-07-30T22:17:05.000Z

Replaced mysql:latest to mysql:5.7 to enable username/password login. Edited pom.xml to compile using Java 1.7 to match tomcat container used in the example.

Answer 5 · 2018-07-30T22:58:48.000Z

works for me. i can also confirm that replacing mysql:latest to mysql:5.6 also works. thanks @spara

sorry about responding on closed issues. But looks like new issue cropped up now and throwing exception on submit. This issue is already open #415

The problem is still there. No files for UserSignup app are found in target container
root@4c7af6cb74d3:/usr/local/tomcat/webapps/UserSignup# ls -al
total 4
drwxr-xr-x 2 root root 40 Sep 6 22:24 .
drwxr-xr-x 8 root root 4096 Sep 7 00:03 ..
root@4c7af6cb74d3:/usr/local/tomcat/webapps/UserSignup#

Running docker on win10 host. seems like a windows integration problem?

Not sure if others are having this problem, but the issue for me was that there weren't any files in the UserSignup directory because the volume mount failed.

You can check this by doing this:

$ docker exec -ti javadebugging_webserver_1 bash
root@0e5b07c5c0b7:/usr/local/tomcat# ls
BUILDING.txt     LICENSE  README.md      RUNNING.txt  conf     lib   native-jni-lib  webapps
CONTRIBUTING.md  NOTICE   RELEASE-NOTES  bin          include  logs  temp            work
root@0e5b07c5c0b7:/usr/local/tomcat# cd webapps/
root@0e5b07c5c0b7:/usr/local/tomcat/webapps# ls
ROOT  UserSignup  docs  examples  host-manager  manager
root@0e5b07c5c0b7:/usr/local/tomcat/webapps# cd UserSignup/
root@0e5b07c5c0b7:/usr/local/tomcat/webapps/UserSignup# ls
META-INF  WEB-INF  assets  bootstrap  datepicker  index.jsp  jquery-1.8.3.js

If that last ls doesn't display anything in that folder, the volume mount failing is the issue.

In just a moment, the file disappeared again

Answer 11 · 2020-05-06T02:16:50.000Z

When I click on the /UserSignUp on the tomcat web application manager, I also get the HTTP Status 404 – Not Found.

I checked the docker file for registration-database and it is using mysql:5.7

Is this exercise working beyond this for the windows 10 home edition with linux o/s on virtual box case.

Thanks
