Why the web page keeps saying 'Context Root Not Found'?

[t2833813]

I do exactly what the tutorial says but in the final step, when I enter the url, it keeps saying 'Context Root Not Found' on the web page and there is no web application appearing. Why did that happen? When I enter maven clean install, there are several WARNINGs, are those relevant to this issue?

Hello,

I just verified the steps on my side and it works fine.

Could you have a look to the Liberty logs under your Liberty installation, please ?

You should see these lines if you correctly copy miniloan-webapp.war under wlp-webProfile8-20.0.0.3\wlp\usr\servers\testGettingStarted\apps :

Thank you for your answer! Actually I didn't see the above lines in the log file. So what should I do to fix it? I think I have finished all the steps in the tutorial and don't know which part is wrong.

Hello,
If you don't see any trace in your messages.log (especially no trace related to the load of miniload-webapp), I would say that miniloan-webapp.war has not been added to folder :
wlp-webProfile8-20.0.0.3\wlp\usr\servers\testGettingStarted\apps
or you didn't add the following lines to your server.xml located at wlp-webProfile8-20.0.0.3\wlp\usr\servers\testGettingStarted

<!-- Miniloan application -->
 <webApplication id="miniloan-webapp"
 location="miniloan-webapp.war"
 name="miniloan-webapp"/>

Could you have a look, please ?
If the problem persists, could you provide me more information (Java version, Liberty version, logs, ...) ?
Hope this helps,
Christian

Hi, I have checked the miniloan-webapp.war as well as server.xml and all things should be all right. I will give you my java version and logs will be attached.

java version "1.8.0_141"
Java(TM) SE Runtime Environment (build 1.8.0_141-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.141-b15, mixed mode)

As for the Liberty version, I am not sure how to check them. May I have some clues on that one? Thanks a lot!
p.s. As my system runs in Chinese language, the log files are also written in Chinese. You may want to use Google translation to get the English version of those.
