Can MongoDb be embedded in a Java program?
If it can't be embedded, is there any NoSQL database that can be embedded?
By embedded I mean packaged with a Java app so that a user will not need to set up a database, just install and start using.

I have a Java Spring MVC web application.
To run it, users have to install and configure a MySQL database for it to connect to (to load configuration and store user info and so on).
Is there a way to include an SQL database in the WAR file that is ready to use, so users don't have to set up the MySQL database?
You can try using SQLite by following this guide available on baeldung.
In-Memory Database like SQLite or HSQLDB or H2 should be used in case you want the data not to be persisted.
I want to run an Java EE application which uses Hibernate and a H2 database in the cloud, e.g. in EC2. The application offers a REST interface and modifys the (currently in local develop mode) in memory H2 database.
Is it possible to deploy the application in EC2 (e.g. with Tomcat server) with a H2 database in file mode, so that the database will not reset during restart of the server and persist the data?
Wikipedia states that derby database can be embedded in a java application. Does it mean that we do not need to install a database server separately as if we were using Mysql for the same application?
Does it mean that we can simply ship a jar file with the database embedded in it, and not worry about installing a database server separately?
Yes you are right, Derby is a database internally supported by Java. This database can be of particular use when creating desktop applications or creating applications in which we do not want to install a database server on target machine.
Derby libraries can directly read database files that are held in JAR archives, so no need to install Database servers for this. Derby has all of the features that you would expect from a modern SQL database.
I have a java web application which i'm developing using a local embedded HSQL database. Is there kind of a servlet which I can plug-in into my application and expose it /dbconsole, where I can fire sql statements, inspect tables, fields and table data?
I think you can try H2 Database which is a fast java opensource database. It can be easily embedded and it has a build-in servlet (org.h2.server.web.WebServlet) for db admin usage. We have used it in our production several years and it is very stable.
Here's its web console UI rendered by org.h2.server.web.WebServlet:
Is it possible to have a embedded database in a small web application? What I need is there should not be any need to install any database in the server machine. By just adding a jar in the folder the database should work.
I am using Java EE, and Netbeans as my IDE. If its possible, what are the open source databases that can be embedded.
Any pointers to some good tutorials will be more helpfull.
HSQLDB, a popular embedded database, is just one jar file that you can drop in your application.
SQLite is the big one. MySQL has an embedded server, but you need to purchase a commercial license for it. Firebird also has an embedded server which it's free.
I haven't tried that but thinking about it, I think you can. I have worked with HSQLDB before and all I had to do was to run the embedded db and then run my client. You can do this by creating a cmd script in Windows or .sh script in Linux.
