I am trying to pass database authentication details dynamically when my Web application deploys into tomcat. This process succeeded when using Windows console, but when porting to Linux and executing startup.sh, Tomcat starts the deployed Web Application, but it is not prompting for password.
This isn't the way things are usually done.
The proper idiom is to set up a named JNDI connection pool. It has the credentials and URL at start up; the app server brings it up. See how to do it here.

I'm new to Spring Cloud Data Flow.Web dashboard seems so slow after deployed a stream or task.What's the reason?
I built the local machine on windows as the official guide.
https://dataflow.spring.io/getting-started/
I tried restart docker but it doesn't work
Apparently, there could be many reasons for the slow responsiveness of the SCDF dashboard. Here are some of the things you can check:
Check if you have sufficient resources in your docker setup (CPU & memory)
Check if the slowness is related to the backend doing some operation (downloading the application artifact etc., this is especially true for local setup)

I am creating a program that searches a folder and catalogs all the files it finds in a database. I know how to create a localhost database (or one hosted on a web) and connect to that. But that would require anyone who I give this app to, to have set up their own database.
I would like to be able to have a specific database created for only this application, that lives in the same root folder with the application and can be moved from computer to computer (preferably MySQL). Is this possible?
Turns out what I need is an Embedded database (Apache Derby, SQLite). Thanks guys in the comments!

I'm looking for an Java based Application server which should be controllable within an Java application. I want to be able to start/stop the server within the application.
So far most App servers I looked at Glassfish, JBoss, are all controlled from the OS instead of being able to integrate into an existing Java Application.
Get a look at Winstone or Jetty, they are easy to embed in an application:
