Unable to see Openshift application - openshift

I added a new openshift application. I followed the instructions and uploaded my code via git push.
The upload logs seem to be fine:
1)the ROOT.war got created:

However, when I hit the url(http://opinion-expertviews.rhcloud.com) I am still seeing the
"Welcome to your JBossEWS (Apache/Tomcat) application on OpenShift" screen
What am I missing?
Solved:
I was uploading my files incorrectly. Corrected way:
I compiled my projects into a war file, put it into the webapps
folder at root of the openshift git directory.
removed the pom.xml
file pushed the updated folder to my application
Application now available at:
http://app_name-namespace.rhcloud.com/app_name.
Thanks a lot for your help and guiding me, although it was stupid of me to miss these points

Since you are deploying your war file with a name other than ROOT.war, you will need to visit your application at the context that is the same as the name of the war file you deployed. For example, if your war file was named myapplication.war, your url would be http://app-domain.rhcloud.com/myapplication, to fix this, you can rename your war file ROOT.war, and your application would be available at http://app-domain.rhcloud.com/

SOLVED: Remote mercurial server fails in changegroup.notify with an exception

Pushing changes to a remote mercurial repo is reporting an error in my changegroup.notify hook. It worked with an old 2.7 release of mercurial, but is broken now.
My server has
Python 3.9, hg --version is
Mercurial Distributed SCM (version 6.3.1)
The relevant repo's hgrc has
changegroup.notify = python:hgext.notify.hook
The hook reports an exception:
>: hg --traceback push
pushing to https://[redacted]
searching for changes
remote: adding changesets
remote: adding manifests
remote: adding file changes
remote: added 1 changesets with 1 changes to 1 files
remote: error: changegroup.notify hook raised an exception: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
remote: (run with --traceback for stack trace)
Why the exception, when I am using what is supposed to just work
out of the box?
Update: Re-ran the test pushing from an account on the same machine as the server (thanks #LazyBadger), got the following traceback:
Traceback (most recent call last):
File "/usr/local/lib/python3.9/dist-packages/mercurial/hook.py", line 116, in pythonhook
r = obj(ui=ui, repo=repo, hooktype=htype, **pycompat.strkwargs(args))
File "/usr/local/lib/python3.9/dist-packages/hgext/notify.py", line 589, in hook
n = notifier(ui, repo, hooktype)
File "/usr/local/lib/python3.9/dist-packages/hgext/notify.py", line 326, in __init__
self.stripcount = int(self.ui.config(b'notify', b'strip'))
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
Solution:
Turns out this is the error you get if you haven't updated your hgrc in years. Used to be that adding the hook to your [.]hgrc was all that was required. Now you have to enable notify as well, so, e.g.
[extensions]
notify=
[hooks]
changegroup.notify = python:hgext.notify.hook
You also need some things to allow the email notication to work, for example if you have personal email support on the same server:
[reposubs]
* = [my email on the server]
[email]
from = Mercurial Notification <noreply#mydomain>
[smtp]
host = localhost

Maven / Fabric8 - build an OpenShift container image against a remote OpenShift installation

With Docker I need only provide DOCKER_HOST and appropriate credentials in order for the fabric8 plugin to be able to build my container image. As long as a Docker Registry is available - there is no need to install Docker-related infrastructure on the actual host which does the image build (e.g. my Bamboo agent).
With OpenShift I cannot seem to find a way to do this. It seems instead that I must run the maven goals on a host on which OpenShift has been installed, which must necessarily be a RedHat Linux host.
This seems far more complicated than it should be. Am I missing something here?
Is there a way to reference a remote OpenShift environment from the fabric8-maven-plugin when in openshift mode?
Thanks, Robin.
I'm from Fabric8 team. You don't need to run goals from host on which OpenShift has been install. Plugin reads your ~/.kube/config for information related to your OpenShift cluster and uses your API token in order to interact with OpenShift REST API.
Fabric8 Maven Plugin has been migrated to Eclipse JKube. Although Fabric8 Maven Plugin also works just fine with remote OpenShift Clusters. It's the same Fabric8 Maven Plugin but with a different name and targeted OpenShift Plugin. I would give this answer with Eclipse JKube's OpenShift Maven Plugin. You can have it in your pom.xml like this:
<dependency>
<groupId>org.eclipse.jkube</groupId>
<artifactId>openshift-maven-plugin</artifactId>
<version>1.0.0</version>
<type>maven-plugin</type>
</dependency>
Here is a demo using a simple Random generator application: https://github.com/rohanKanojia/eclipse-jkube-demo-project
Log into your OpenShift Cluster with credentials provided:
~ : $ oc login https://your-cluster.openshift.com--token=your-token
Logged into "https://your-cluster.openshift.com:443" as "rohanKanojia" using the token provided.
You have one project on this server: "rokumar"
Using project "rokumar".
Go to your project and Issue OpenShift Maven Plugin goals:

How to deploy Express 4 application with mysql database setup on openshift?

I am finding it difficult to deploy the Express4 app on Openshift.
The project is working fine on localhost but not being able to push on server

The express#3 version works fine on server.js(default they provide).
Any help for deploying express#4 version on openshift ???

I have my web.xml in webapp/WEB-INF/web.xml and in .openshift/config/web.xml
I'm also confused about webapp vs. WebContent.
The web.xml file must be placed under src/main/webapp/WEB-INF. The error you are getting is because Maven is not finding web.xml at this location.
Also, I will take a wild guess but I presume WebContent is the folder generated by Eclipse when you create a web-application. If this folder is present, then there is a issue with your Eclipse project configuration. You should follow Maven conventions through out your project (and add the Maven nature to your Eclipse project with the m2e plugin).

Maven mercurial extension constantly fails

After 2+ hours I was able to get the maven-scm-provider-hg extension (for pushing to mercurial repos from Maven) semi working, meaning that it was executing commands instead of just giving errors.
However I think I've run into a wall with this error

Any suggestions?
Firstly, not sure if deploying the project artifacts to an SCM is a normal practice. maven scm plugin is usually used for source code related operations like checkout/update/tag, etc.
Secondly, the cause of the error seems to be related to the fact that maven scm provider for hg does not support the list command as specified in this scm providers matrix. Not sure why and how mvn deploy uses this command though.
