A Url Shortener using only pure Java.
Please change the value of storage.folder.path in the file src/main/config/config.properties. Is necessary to point to a folder where it's possible to read and write files.
Don't forget to use at the end of the given path / if you are running on Unix, Mac or Linux systems, or \ for Windows.
If desired, also change the value of url.root.
I tested locally using both Eclipse and Netbeans with Tomcat 9.
Running the tests will ensure that the changed settings are working.
Browser requests are handled primarily by these files:
This file displays the main user interface. This will call the HomeRequestManager class, which will handle the request, shortening the URL if it is informed, or returning errors if applicable.
This servlet, as its name implies, takes all requests where there is no page or file defined, waiting for URIs such as /abcd123 which would be the short keys to find the original URLs stored in the persistence layer. If a stored full URL is found, the user will be redirected to it, otherwise an 404 error will be displayed.
