sendRedirect is sending a response code like 302 or 304 (I assume 302 Temporary Redirect) to the browser and a Location header telling the client where to go instead. This is then handled transparently by the browser, without it ever having to display anything.

To see the HTTP response for yourself use curl -v http://yourendpoint, or use Postman if you prefer a browser based tool. Or you can look at the request/response in your browser dev tools, under the network tab (you might have to find an option that doesn't clear the inpector history on page load).

Alternatively you would pass the redirect url to the page and do the redirect later with javascript.

You could respond with something like this, to display the page and redirect after 3 seconds:

You need to add your configuration at the plugin level rather than the execution level.

So it should look more like:

As Piotr P. Karwasz said it, I misspelled dataSourceName in context.xml and server.xml file. I feel bad that I didn't notice it.

But I still have one question : In which document should I put the realm tag ?

I had the same issue while reproducing the problem reported at IntelliJ IDEA forums.

It didn't work with Tomcat 10 for the reasons described in the answer by Piotr P. Karwasz, but it works just fine with Tomcat 9.0.44 and earlier versions.

It is theoretically possible to store all keys and values from a ResourceBundle in a serializable object, but you don’t need to. You can just store the Locale and the name of the ResourceBundle in your session.

A web application has the same classpath for its entire lifetime, so the ResourceBundle will always be available by that name.

It's giving the error that "org.glassfish.jersey.servlet.ServletContainer" is missing in the Class path. Because of which the application is not starting.

See the version of Jersey that is compatible with WAS 8.5.5? (I think it's Jersey 1.x). The corresponding library needs to be used.

That is the way welcome resources are supposed to work:

The container may send the request to the welcome resource with a forward, a redirect, or a container specific mechanism that is indistinguishable from a direct request.

(Servlet 5.0 Specification)

Tomcat redirects the request internally. If you want to send a HTTP redirect, you need to do it yourself. You can check the original URI to see if the request was forwarded by the welcome files mechanism:

Remove the .class suffix

The UserDatabaseRealm (cf. documentation) requires a resource of type org.apache.catalina.UserDatabase (not to be confused with a database connection pool, which is of type javax.sql.DataSource).

In your configuration you provided the wrong object factory class name: you used org.apache.tomcat.jdbc.pool.DataSourceFactory, which creates Tomcat JDBC connection pools, instead of org.apache.catalina.users.MemoryUserDatabaseFactory.

Just use:
