stack commented on HTRACE-247:
------------------------------
So, the webapp is from htrace-htraced. It is what it uses. If you start
htrace-htraced, it should be putting it up for you to query.
We broke out the webapp to be its own separate module though because the notion
was that it should be developed apart from htrace-htraced. The idea is that one
day this webapp could be deployed for htrace-htraced but also in other
containers; e.g. deployed in the hbase UI. A bit of config for the container
would point it at the span store it should query. The work to make it useable
for any store other than htrace-htraced has not yet been done. You are the
first to try the webapp running apart from htrace-htraced so there are likely
some issues.

> Right now I literally have no idea how to use the Web Application. This issue
> became apparent to me whilst trying to build the docker container and running
> into some Tomcat issues, then investigating the Web App locally only to find
> out that I couldn't package it. I then logged HTRACE-246.
> When I deployed the web app into Apache Tomcat and navigated to
> http://localhost:8080/htrace-webapp-4.1.0-incubating-SNAPSHOT/#about I am
> greeted with some concerning message the there is an error with regards to a
> REST service not being found!
> Please see the attached screenshot which shows you what I am seeing.
> I have tried starting up the REST server as per
> {code}

> However this does not resolve the issue and I still cannot bind to any RESt
> service at the /server/info endpoint.
> Can anyone help me to understand this?
> The issue describes the fact that we need to augment the documentation for
> the Web Application. Whether or not that happens in the webapp README I don't
> care. But the documentation should be easy to find.
> Thanks folks.
