I expect my app to serve login module by default but base href

Also it would be of great help if some one helps me to figure out how to achieve this in a micro-services architecture.

How to remove duplicates in my WEB-INF/lib jar files?

I know there seems to be a lot of discussion on StackOverflow about the error I am getting, but I don't see exactly the same situation and I'd like to better understand the issue I am having.
I am getting the following failed to start error "Caused by: org.apache.catalina.LifecycleException: A child container failed during start"
After doing some research it seems like this is a WEB-INF/lib and/or a pom.xml dependency issue. It looks like people have been able to solve their issues by removing a variety of jar files or updating their pom file/removing a variety of certain dependencies.
When I look at my WEB-INF/lib jar files, it seems that mine are duplicating... Does any one know why I am getting double/2 versions of the same jar files, and could they tell me which dependency they are coming from in my pom.xml file? I think my project wont start on Tomcat & is getting this issue due to the duplicates, as things are already running once when it tries to start the other duplicate jar files.

Unable to run spring boot application on openshift

I have deployed a spring boot project on open shift stater gen 3. It was perfectly a few days ago. But yesterday I rebuilt it and it gave me this "Application is not available".I deployed it through this.

I cannot use the c taglib in my jsp using spring boot

I know this is very late to answer this question but it can help someone else who come across the same problem.
I removed
