They are then run as well as managed by using the J2EE server. Web Clients Web clients generally consist of two distinctive parts. However, it does open a possibility to include a command-line interface. Servlets are smaller Java programs that essentially run within a web server.
The tough choice is while deciding which one they should use as it leads to trade-offs between two factors: Keeping the functionality intact with the user and client for the thick client Off-loading the necessary functionality that the server needs and can handle for the thin client When you off-load the server's necessary functionality, the distribution gets more straightforward, much seamless while deploying and governing the application.
